Identification of a novel domain shared by putative components of the endocytic and cytoskeletal machinery. (1/990)

We have identified a approximately 140 amino acid domain that is shared by a variety of proteins in budding and fission yeast, nematode, rat, mouse, frog, oat, and man. Typically, this domain is located within 20 residues of the N-terminus of the various proteins. The percent identity among the domains in the 12 proteins ranges from 42 to 93%, with 16 absolutely conserved residues: N-x(11-13)-V-x2-A-T-x(34-36)-R-x(7-8)-W-R-x3-K-x12-G-x-E-x15 -L-x11-12-D-x-G-R-x11-D-x7-R. Even though these proteins share little beyond their segment of homology, data are emerging that several of the proteins are involved in endocytosis and or regulation of cytoskeletal organization. We have named this protein segment the ENTH domain, for Epsin N-terminal Homology domain, and hypothesize that it is a candidate for binding specific ligands and/or enzymatic activity in the cell.  (+info)

Divergence time estimates for the early history of animal phyla and the origin of plants, animals and fungi. (2/990)

In the past, molecular clocks have been used to estimate divergence times among animal phyla, but those time estimates have varied widely (1200-670 million years ago, Ma). In order to obtain time estimates that are more robust, we have analysed a larger number of genes for divergences among three well-represented animal phyla, and among plants, animals and fungi. The time estimate for the chordate-arthropod divergence, using 50 genes, is 993 +/- 46 Ma. Nematodes were found to have diverged from the lineage leading to arthropods and chordates at 1177 +/- 79 Ma. Phylogenetic analyses also show that a basal position of nematodes has strong support (p > 99%) and is not the result of rate biases. The three-way split (relationships unresolved) of plants, animals and fungi was estimated at 1576 +/- 88 Ma. By inference, the basal animal phyla (Porifera, Cnidaria, Ctenophora) diverged between about 1200-1500 Ma. This suggests that at least six animal phyla originated deep in the Precambrian, more than 400 million years earlier than their first appearance in the fossil record.  (+info)

Isolation of the LEMMI9 gene and promoter analysis during a compatible plant-nematode interaction. (3/990)

Plant-endoparasitic root-knot nematodes feed on specialized giant cells that they induce in the vascular cylinder of susceptible plants. Although it has been established that a number of plant genes change their expression pattern during giant cell differentiation, virtually no data are available about the mechanisms involved in that change. One possibility is differential promoter recognition by the transcription factor(s) responsible for the expression of specific genes. We have isolated and characterized a genomic clone from tomato containing the promoter region of LEMMI9, one of the few plant genes that have been reported to be highly expressed in galls (predominantly in giant cells). The analysis of transgenic potato plants carrying a LEMMI9 promoter-beta glucuronidase (GUS) fusion has demonstrated that the tomato promoter was activated in Meloidogyne incognita-induced galls in a heterologous system. We have located putative regulatory sequences in the promoter and have found that nuclear proteins from the galls formed specific DNA-protein complexes with the proximal region of the LEMMI9 promoter. The nuclear protein-binding sequence mapped to a region of 111 bp immediately upstream from the TATA box. This region contains a 12-bp repeat possibly involved in the formation of DNA-protein complexes, which might be related to the LEMMI9 transcriptional activation in the giant cells.  (+info)

Polygalacturonase and polygalacturonase inhibitor protein: gene isolation and transcription in Glycine max-Heterodera glycines interactions. (4/990)

The cell wall acts as the first line of defense during pathogen invasion. Polygalacturonases (PGs) are a class of cell-wall-modifying enzymes with precise temporal and organ-specific expression. A 350-bp fragment with high homology to PGs was identified by differential display (DD) analysis of soybean cyst nematode (SCN) race 3 resistant PI 437654 and susceptible cultivar Essex. The fragment was strongly expressed in Essex, 2 days after inoculation (DAI). Complete coding sequences of two PG cDNAs, PG1 and PG2, were isolated by 3' and 5' rapid amplification of cDNA ends polymerase chain reaction (RACE PCR). PI 437654 and Essex had identical PG1 and PG2 sequences. A transversion from A to C created a PstI restriction site in the PG2 cDNA that was used to distinguish the two PG cDNAs by cleaved amplified polymorphic sequence (CAPS) analysis. A cDNA encoding a polygalacturonase-inhibitor protein (PGIP) that is 89% identical to the Phaseolus vulgaris PGIP was isolated from soybean roots by reverse transcription (RT)-PCR. Steady-state levels of PG and PGIP were investigated by RNA gel blot analysis in roots 1 to 5 DAI and in hypocotyls and leaves. Differences in the constitutive levels of PG mRNAs were observed in roots of different soybean genotypes. Steady-state levels of PG mRNAs were enhanced during compatible interactions with SCN and reduced in incompatible interactions and in mechanically wounded roots. Enhanced PGIP transcription was observed in response to mechanical wounding in both PI 437654 and Essex, but only in compatible interactions with SCN, suggesting uncoupling of PGIP functions in developmental and stress cues. Constitutive expression in incompatible interactions shows PGIP is not a factor in SCN resistance. Thus, the up-regulation of endogenous PG transcription in soybean roots early after SCN infection could facilitate successful parasitism by SCN.  (+info)

The planarian HOM/HOX homeobox genes (Plox) expressed along the anteroposterior axis. (5/990)

In the freshwater planarian Dugesia japonica, five cDNAs for HOM/HOX homeobox genes were cloned and sequenced. Together with sequence data on HOM/HOX homeobox genes of platyhelminthes deposited in databases, comparison of the deduced amino acid sequences revealed that planarians have at least seven HOM/HOX homeobox genes, Plox1 to Plox7 (planarian HOM/HOX homeobox genes). Whole-mount in situ hybridization and RT-PCR revealed that Plox4 and Plox5 were increasingly expressed along a spatial gradient in the posterior region of intact animals. During regeneration, Plox5 was expressed only in the posterior region of regenerating body pieces, suggesting that the gene is involved in the anteroposterior patterning in planarians. Plox5 was not found to be expressed in a blastema-specific manner, which contradicts a previous report (J. R. Bayascas, E. Castillo, A. M. Munos-Marmol, and E. Salo. Development 124, 141-148, 1997). X-ray irradiation experiments showed that Plox5 was expressed at least in some cells other than neoblasts, but that the induction of Plox5 expression during regeneration might require neoblasts.  (+info)

Apoptosis without caspases: an inefficient molecular guillotine? (6/990)

Since the discovery that the cysteine protease CED-3 was essential for developmental death in the nematode C. elegans, the search has been on to identify homologous proteases governing mammalian apoptosis. Fourteen of these proteases, now called caspases, have been found to date, and studies with natural or chemical inhibitors, and more recently knock-out mice, confirmed the involvement of at least a subset of these proteases in various forms of mammalian apoptosis. However, there has been recent evidence that some apoptotic morphologies, such as cell shrinkage, membrane blebbing and nuclear condensation, are not blocked by caspase inhibitors and that the cells continue to die in a protracted and inefficient manner. This has led to the notion that caspases are not required for all aspects of apoptosis in mammals. Here we review the current knowledge about caspase-independent apoptosis, discuss the strengths and weaknesses of the reasoning that led to its proposition and provide insights into its possible regulation and physiological significance.  (+info)

Wild rodents as experimental intermediate hosts of Lagochilascaris minor Leiper, 1909. (7/990)

A total of 25 specimens of Cavia porcellus (guinea pig), 5 Dasyprocta agouti (agouti), and 22 Calomys callosus (vesper mice) were inoculated with infective eggs of Lagochilascaris minor. The inoculum was prepared with embryonated eggs and orally administered to each individual animal through an esophagus probe. In parallel, 100 specimens of Felis catus domesticus were individually fed with 55-70 nodules containing 3rd-stage larvae encysted in tissues of infected rodents. Animals were examined and necropsied at different time intervals. The migration and encystment of L3 larva was observed in viscera, skeletal muscle, adipose and subcutaneous tissues from all rodents. Adult worms localized at abscesses in the cervical region, rhino, and oropharynx were recovered from domestic cats inoculated with infected rodent tissues. Through this study we can conclude that: (1) wild rodents act as intermediate hosts, characterizing this ascarid heteroxenic cycle; (2) in natural conditions rodents could possibly act as either intermediate hosts or paratenic hosts of Lagochilascaris minor; (3) despite the occurrence of an auto-infecting cycle, in prime-infection of felines (definite hosts) the cycle is only completed when intermediate hosts are provided; and (4) in the wild, rodents could serve as a source of infection for humans as they are frequently used as food in regions with the highest incidence of human lagochilascariasis.  (+info)

Studies on Procamallanus (Spirocamallanus) Pereirai annereaux, 1946 (Nematoda: Camallanidae), with new host records and new morphological data on the larval stages. (8/990)

Larval stages and adults of Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 are described from naturally infected Paralonchurus brasiliensis (Steindachner) (Sciaenidae) from the coast of the State of Rio de Janeiro, Brazil. The translucent first-stage larvae have a denticulate process at the anterior end, no buccal capsule or esophagus undifferentiated into anterior muscular and posterior glandular parts and an elongate tail; third-stage larvae have a tail with three terminal projections, a buccal capsule divided into an anterior portion with 12-20 ridges running to the left and a posterior smooth portion, and an esophagus with muscular and glandular regions. Fourth-stage larvae exhibit a buccal capsule lacking a distinct basal ring with ridges running to the right and a tail with two terminal processes, as in adults. New host records are reported and their role in its life-cycle are discussed.  (+info)

Figure 4B shows the polarized SFS of clade C on a double-logarithmic scale such that power laws show as straight lines. At frequencies ,20%, the observed SFS is compatible with a 1/k decay as expected in neutrally evolving populations of constant size (Wakeley 2008). At higher frequencies, however, the SFS decreases much more rapidly, before increasing again for alleles close to fixation. Similar U-shaped SFS have been observed in plants (Cao et al. 2011). At intermediate derived allele frequencies between 20% and 40%, the slope of the SFS is compatible with 1/k2, indicated as a dashed line in Figure 4B. The 1/k2 behavior and the nonmonotonicity are expected if the dominant force changing allele frequencies is selection at linked (genetic draft) loci regardless of whether this variation is positively or negatively selected (Braverman et al. 1995; Neher and Shraiman 2011; Neher and Hallatschek 2013)..

Analysis of expressed sequence tags from the ectoparasitic nematode Xiphinema index » Brill OnlineAnalysis of expressed sequence tags from the ectoparasitic nematode Xiphinema index » Brill Online
We report the results of a small-scale expressed sequence tag project performed on the ectoparasitic nematode Xiphinema index. Approximately 1400 genes were sequenced, 70% from a cDNA library generated from dissected basal bulbs (containing the pharyngeal gland cells) and 30% from cDNA libraries generated from whole mixed stage nematodes. A large portion of the bulb library (48%) was composed of proteins with no matches in the database. Further analysis of these genes revealed that a total of 51 contigs were present, half of which encoded novel secreted proteins. By contrast, the whole nematode library contained more housekeeping and nematode-specific genes. Only one of the novel genes from the whole nematode library had a predicted signal peptide at the N-terminus. Genes encoding transthyretin-like proteins were abundant in the bulb library and in situ hybridisation confirmed that one of these is expressed in the basal bulb. Genes encoding a variety of proteases, which were shown using in situ

Soybean Cyst Nematode: Diagnosis and Management | MU ExtensionSoybean Cyst Nematode: Diagnosis and Management | MU Extension
Soybean cyst nematode (SCN) is the most devastating and yield limiting pest of soybean in the U.S. including Missouri. A recent three-year study done in the United States estimated that soybean cyst nematode (Heterodera glycines) caused annual losses of $1.286 billion (128.6 million bushels).. It is often difficult to identify fields with SCN infestations becauselow numbers of SCN will cause little damage to roots so above ground plant growth and appearance may be normal (Figure 1). Stunting of plant growth, visible changes in leaf color and wilting, and yield loss will increase as the infection of roots by SCN increases.Yields may decrease slowly for a number of years as the population of SCN increases in the soil and infection of roots increases. Suspect fields usually have plants of different heights, but environmental conditions may make stunting less obvious.. When SCN is present and plants are under stress, symptoms such as chlorosis (Figure 2), plant stunting, and (in extreme cases) plant ...

The efficiency with which the nematophagous fungus Arthrobotrys dasguptae attached to a range of plant parasitic nematodes was studied. Rotylenchus spp. and criconematid species retained many more detachable adhesive knobs than did other plant parasitic nematodes. More adhesive knobs were found on the anterior end of Rotylenchus robustus than on any other part of the body. The knobs attached only to one of the species tested in the genera Longidorus, Xiphinema, Trichodorus and Paratrichodorus. Tests with a range of fluorescent lectins indicated that only a restricted number of carbohydrate moieties were present on the cuticle of R. robustus whereas none were found on Xiphinema diversicaudatum. Saturating fungus and nematodes with these lectins or their specific carbohydrates did not affect the subsequent adhesion of A. dasguptae to the cuticle of R. robustus.

Infection Assay of Cyst Nematodes on Arabidopsis Roots -BIO-PROTOCOLInfection Assay of Cyst Nematodes on Arabidopsis Roots -BIO-PROTOCOL
Plant parasitic nematodes are devastating pests on many crops. Juveniles (J2) of cyst nematodes invade the roots to induce a syncytium. This feeding site is their only source of nutrients. Male nematodes leave the roots after the fourth molt to mate with females. The females stay attached to their syncytia throughout their life and produce hundreds of eggs, which are contained in their bodies. When the females die their bodies form the cysts, which protect the eggs. Cysts can survive for many years in the soil until favorable conditions induce hatching of the juveniles. The beet cyst nematode Heterodera schachtii is a pathogen of sugar beet (Beta vulgaris) but can also complete its life cycle on Arabidopsis roots growing on agar plates under sterile conditions. We present here protocols for a stock culture of H. schachtii and an infection assay on agar plates.

The promoter of a plant defensin gene directs specific expression in nematode-induced syncytia in Arabidopsis roots - WRAP:...The promoter of a plant defensin gene directs specific expression in nematode-induced syncytia in Arabidopsis roots - WRAP:...
The beet cyst nematode Heterodera schachtii induces a feeding site, called syncytium, in roots of host plants. In Arabidopsis, one of the genes whose expression is strongly induced in these structures is Pdf2.1 which codes for an antimicrobial plant defensin. Arabidopsis has 13 plant defensin genes. Besides Pdf2.1, the Pdf2.2 and Pdf2.3 genes were strongly expressed in syncytia and therefore the expression of all three Pdf genes was studied in detail. The promoter of the Pdf2.1 gene turned out to be an interesting candidate to drive a syncytium-specific expression of foreign genes as RT-PCR showed that apart from the feeding site it was only expressed in siliques (seeds). The Pdf2.2 and Pdf2.3 genes were in addition expressed in seedlings, roots, leaves, stems, and flowers. These results were supported by the analysis of promoter::GUS lines. After infection with H. schachtii all GUS lines showed a strong staining in syncytia at 5 and 15 dpi. This expression pattern was confirmed by in situ ...

N2 - Root-feeding nematodes are major soil-borne pests in agriculture. In natural ecosystems, their abundance can be strongly controlled by natural enemies. In coastal foredune soil, the abundance of the ectoparasitic nematode Tylenchorhynchus ventralis is controlled by local interactions with soil microorganisms. If not controlled, T. ventralis reduces growth and performance of the host plant Ammophila arenaria. In the present study, we examine if the nematodes may sense the presence of soil microorganisms and, if so, they are able to actively avoid their enemies. First, using Petri dishes with agar medium we examined if T. ventralis can choose between A. ...

Desiccation Survival in an Antarctic Nematode: Molecular Analysis Usin by Byron J. Adams, Bishwo N. Adhikari et al.Desiccation Survival in an Antarctic Nematode: Molecular Analysis Usin by Byron J. Adams, Bishwo N. Adhikari et al.
Background: Nematodes are the dominant soil animals in Antarctic Dry Valleys and are capable of surviving desiccation and freezing in an anhydrobiotic state. Genes induced by desiccation stress have been successfully enumerated in nematodes; however we have little knowledge of gene regulation by Antarctic nematodes which can survive multiple environmental stresses. To address this problem we investigated the genetic responses of a nematode species, Plectus murrayi, that is capable of tolerating Antarctic environmental extremes, in particular desiccation and freezing. In this study, we provide the first insight into the desiccation induced transcriptome of an Antarctic nematode through cDNA library construction and suppressive subtractive hybridization. Results: We obtained 2,486 expressed sequence tags (ESTs) from 2,586 clones derived from the cDNA library of desiccated P. murrayi. The 2,486 ESTs formed 1,387 putative unique transcripts of which 523 (38%) had matches in the model-nematode Caenorhabditis

New cyst nematode species on corn | Integrated Crop Management
Iowa crop producers and agronomists are well aware of soybean cyst nematode (SCN), the plant-parasitic nematode that is widespread through the Midwest and can seriously reduce soybean yields. And many people are aware of other plant-parasitic nematodes that can cause significant yield reductions on corn. But most crop professionals probably are unaware that there is a corn cyst nematode that has been in the northeastern United States since 1981. And just recently, a new cyst nematode species that reproduces on corn was discovered in Tennessee.

Coevolution of Xiphinema americanum plant parasitic nematodes and their bacterial endosymbionts
Symbiosis takes place across the domains of life. In the plant-parasitic nematode, Xiphinema americanum species complex, the bacterial endosymbiont, identified as Candidatus Xiphinematobacter americanum, lives in the gut epithelia of mature female nematodes and moves to the ovaries and uterus where it is transmitted to the eggs. This suggests that the symbiont may be vertically transmitted. PCR followed by DNA sequencing was conducted on three loci, using nematode samples from across North America. Two loci were sequenced from the symbiont and the third from the mitochondrial DNA of the nematode. Using these sequences, phylogenetic trees were constructed for the nematode and the symbiont to provide new insights into the taxonomy of the nematode species, and to shed light on the potential for coevolution between the worm and its endosymbiont. A mitochondrial tree was constructed to examine nematode evolution. Mitochondrial phylogenetic analysis for the nematode built from work that suggested ...

Plants mount defense responses during pathogen attacks, and robust host defense suppression by pathogen effector proteins is essential for infection success. 4E02 is an effector of the sugar beet cyst nematode Heterodera schachtii. Arabidopsis thaliana lines expressing the effector-coding sequence showed altered expression levels of defense response genes, as well as higher susceptibility to both the biotroph H. schachtii and the necrotroph Botrytis cinerea, indicating a potential suppression of defenses by 4E02. Yeast two-hybrid analyses showed that 4E02 targets A. thaliana vacuolar papain-like cysteine protease (PLCP) Responsive to Dehydration 21A (RD21A), which has been shown to function in the plant defense response. Activity-based protein profiling analyses documented that the in planta presence of 4E02 does not impede enzymatic activity of RD21A. Instead, 4E02 mediates a re-localization of this protease from the vacuole to the nucleus and cytoplasm, which is likely to prevent the ...

Heterodera schachtii - WikipediaHeterodera schachtii - Wikipedia
Heterodera schachtii (Beet cyst eelworm, Sugarbeet nematode) is a plant pathogenic nematode. It infects more than 200 different plants including economically important crops such as sugar beets, cabbage, broccoli, and radish. H. schachtii is found worldwide. Affected plants are marked by stunted growth, wilting, yellowing, decreased yields, and death. While there are many methods of control, crop rotation with non-susceptible plants is preferred. In the early 1800s, beet fatigue was used to describe the decreased sugar beet yields which occurred after repeated planting on the same field. At first, this decrease was believed to be the result of nutrient depletion, but in 1859 the botanist H. Schacht discovered nematode cysts on the roots of affected plants and hypothesized that they were responsible for the disease. It wasnt until 1871 that another researcher, Schmidt, created the genus Heterodera, and named the nematode H. schachtii in honor of its discoverer. Chemicals released from a ...

Potato Cyst Nematodes (or eelworms)
From: http://www.sasa.gov.uk/seed-ware-potatoes/nematology/potato-cyst-nematodes-pcn. To understand the importance of Potato Cyst Nematodes in potato cultivation it is helpful to know a little of the life history of these pests.. The nematodes (or eelworms) survive as cysts in the soil. Each cyst, about the size of a pinhead, will contain up to 400 juvenile nematodes each enclosed within a thin egg shell. When a potato crop is planted in infested soil, substances released from the growing roots stimulate a high percentage of juvenile nematodes to hatch. After hatching these juveniles swim through the moisture surrounding the soil particles and cut their way into the potato roots to feed. The damage they cause produces a stunted root system and the plant responds by producing many additional lateral roots. Severe root damage may result in patches of poor top growth but such damage is unlikely in seed crops.. The young nematodes develop in the roots, feeding on the growing plant. Males remain ...

Corn cyst nematode - WikipediaCorn cyst nematode - Wikipedia
The corn cyst nematode (CCN) Heterodera zeae is a plant parasitic nematode that feeds on corn Zea mays. The CCN has a limited economic impact worldwide due to its high soil temperature requirements. CCN was first described from a population in India in 1970. It was later reported in Egypt and Pakistan. In India the CCN is considered to be one of the four economically important cyst nematodes. The first report of the species in the Western hemisphere came in 1981 from four colonies in Maryland, Harford, Cecil, Kent, and Queen Annes counties. These four counties were placed under quarantine. The nematode was later identified from Cumberland Co., VA, over 170 miles from the nearest known infested field in Maryland. In Virginia the nematode was restricted to a 3 by 2.5 mile strip of land along the Appomattox River. The cysts of CCN are light brown in color and lemon shaped. The cysts also have a zig-zag pattern on the cyst wall with four prominent finger-like bullae below the underbridge. The ...

British Library EThOS: Mode of action studies on the nematicide fluensulfoneBritish Library EThOS: Mode of action studies on the nematicide fluensulfone
Plant parasitic nematodes (PPNs) place a heavy burden on agriculture throughout the world. This burden is accentuated by a lack of effective and safe methods for the control of these crop pests, with many nematicides having been banned due to unacceptable non-target toxicity. Few alternatives have emerged to fill this gap. Fluensulfone is a newly registered nematicide that has a favourable toxicity profile relative to previously used nematicides. Fluensulfone has proven efficacy in the field against a range of nematode species. The mode of action of fluensulfone is however currently unknown. The aim of this thesis was to investigate the effects of fluensulfone on nematodes and to gain insight into its mechanism of action. Caenorhabditis elegans is a model organism with well characterised genetics, neurophysiology and behaviour. C. elegans has proven useful in previous mechanism of action studies on anthelmintics. Fluensulfone was found to have nematicidal activity against C. elegans but at ...

Interpretive Summary: Plant-parasitic cyst nematodes are agriculturally-important pests causing significant yield losses on many crop plants. Recent studies revealed that cyst nematodes secret CLAVATA3/ESR (CLE)-like proteins that are required for successful nematode infection. However, the host receptors that interact with nematode-secreted CLE peptides have not been identified. In this study, we used the model plant Arabidopsis, a host for the sugarbeet cyst nematode, to investigate a role for CLV2 and CORYNE (CRN) in nematode CLE signaling. Our results revealed for the first time that CLV2 and CRN are required for perceiving nematode CLE signals to promote successful nematode parasitism. This study provides new knowledge in nematode CLE-mediated parasitism, suggesting new targets that may be useful for generating transgenic crops with novel resistance to cyst nematodes. Technical Abstract: Plant-parasitic cyst nematodes secrete CLAVATA3 (CLV3)/ESR(CLE)-like effector proteins. These proteins ...

Bioinformatic exploration of RIO protein kinases of parasitic and free-living nematodesBioinformatic exploration of RIO protein kinases of parasitic and free-living nematodes
Despite right open reading frame kinases (RIOKs) being essential for life, their functions, substrates and cellular pathways remain enigmatic. In the present study, gene structures were characterised for 26 RIOKs from draft genomes of parasitic and free-living nematodes. RNA-seq transcription profiles of riok genes were investigated for selected parasitic nematodes and showed that these kinases are transcribed in developmental stages that infect their mammalian host. Three-dimensional structural models of Caenorhabditis elegans RIOKs were predicted, and elucidated functional domains and conserved regions in nematode homologs. These findings provide prospects for functional studies of riok genes in C. elegans, and an opportunity for the design and validation of nematode-specific inhibitors of these enzymes in socioeconomic parasitic worms ...

MINT NEMATODE LIFE CYCLEMINT NEMATODE LIFE CYCLE
Mint nematodes (Longidorus elongatus) are also referred to as needle nematodes because of their long, slender stylet. The mint nematode was originally identified in 1956 as L. sylphus, but was later described as a new species, L. menthasolanus, (Konicek and Jensen, 1961), and then finally determined to be L. elongatus. In contrast to pin nematodes, mint nematodes are the largest (5 mm = 0.2 inch) plant-pathogenic nematodes found on any plant (Fig. 1). They are among the few nematodes which can be detected with the naked eye and can sometimes be seen coiled around rudimentary rhizomes or roots of mint when clods are broken open during July and August (Konicek, 1961, Pinkerton and Jensen, 1983). Mint nematodes belong to a different taxonomic class than other nematodes parasitizing mint and do not possess a muscular median bulb in their esophagus. Mint nematodes were the first nematodes associated with decline in mint when nearly 10% of peppermint acreage was estimated to be infested in 1958 ...

Stalactites (CaCO3 and salt) from water seeps are frequently encountered in ceilings of mine tunnels whenever they intersect water-bearing faults or fractures. To determine whether stalactites could be mineralized traps for indigenous fracture water microorganisms, we analyzed stalactites collected from three different mines ranging in depth from 1.3 to 3.1 km. During sampling in Beatrix gold mine (1.4 km beneath the surface), central South Africa, CaCO3 stalactites growing on the mine tunnel ceiling were collected and observed, in two cases, to contain a living obligate brackish water/marine nematode species, Monhystrella parvella. After sterilization of the outer surface, mineral layers were physically removed from the outside to the interior, and DNA extracted. Based upon 16S and 18S rRNA gene sequencing, Archaea, Bacteria, and Eukarya in different combinations were detected for each layer. Using CT scan and electron microscopy the inner structure of CaCO3 and salt stalactites were analyzed. CaCO3

Unravelling of soil nematode biodiversity is an essential task in order to increase the knowledge about ecological phenomenon from the evolutionary, biogeographical and physical processes in soil ecosystems. In a phytopathological context, deciphering the diversity of plant-parasitic nematodes (PPN) infesting soils from an agricultural ecosystem is an essential task in order to design useful management practices for controlling potential nematode diseases. Overall, most of PPN have a broad range of host plants, natural plants or crops including annual, biannual or perennial plants. Similarity to their wide host range as generalist nematodes, there are plants that can host a wide range of PPN, as is the case for olive trees. In fact, olives, both in wild and cultivated forms, serve as hosts to a wide diversity of PPN, including endoparasitic, semiendoparasitc and ectoparasitic species. Approximately 50% of the total surface area of Andalusia region is covered with natural and forest vegetation, ...

www.diark.org. Arthrobotrys oligospora (syn. Didymozoophaga oligospora) is a predacious fungus from the family Orbiliaceae. An adaptable fungus, strains have been found in a diverse range of soils where they can act as saprophytes, fungal pathogens and colonise plant roots to obtain nutrients. In the presence of nematodes they can also form complex three-dimensional network traps making them a biocontrol candidate for parasitic plant and animal nematodes, and in 2011 it was the first nematode-trapping fungi to have its genome sequenced.. The sequenced genome of A. oligospora is 40 Mb and contains 11,479 predicted genes. Comparative analyses revealed that it shares more genes with pathogenic fungi than non-pathogenic fungi. A combination of genomic, proteomic and qPCR data led to a hypothesis of trap formation involving the activation of multiple signal transduction pathways by the presence of the nematodes which regulate downstream genes involved in energy metabolism, biosynthesis of the cell ...

Nematode-trapping fungi have fascinated scientists for decades, and many earlier workers have observed the way in which the presence of nematodes alters the morphology and metabolism of trap-forming species. Although earlier studies detected attractant and nematocidal metabolites by their activities, the compounds were never chemically identified (21-27, 30). Therefore, we hypothesized that these signaling molecules might be volatile in nature. In our analyses, we used GC-MS and were able to separate and chemically characterize the metabolites, as well as elucidate their biological activities in attracting nematodes, in inducing trap formation, or in killing nematodes.. Under direct physical contact with nematodes, fungi grown on CMA produced more 3D traps than those grown on PDA and did so at a higher rate. Similar results were obtained in the non-direct-contact bioassay; however, instead of 3D trap formation, fungal hyphal fusions were observed in the nondirect assay. The fungi grown on CMA ...

All major crops are thought to be infected by at least one species of plant-parasitic nematode, which causes damage valued at over $80 billion each year [1]. The majority of these economic losses are attributable to the sedentary endoparasitic nematodes of the genus Meloidogyne (root-knot nematodes) and the genera Heterodera and Globodera (cyst nematodes). These sedentary endoparasites have complex biotrophic interactions with their hosts that include induction of specific feeding sites and long residence times within or on their host(s).. Potato cyst nematodes (PCN) are economically important pathogens of potato, with two major species: the white PCN Globodera pallida and the yellow PCN G. rostochiensis. These nematodes originate in South America [2, 3] and have subsequently been introduced into all major potato-growing regions of the world. Europe has acted as a secondary distribution hub for PCN; worldwide populations outside South America reflect subsequent introductions from Europe [4, 5]. ...

Parasitic nematodes produce at least two structurally novel classes of small helix-rich retinol- and fatty-acid-binding proteins that have no counterparts in their plant or animal hosts and thus represent potential targets for new nematicides. Here we describe a protein (Gp-FAR-1) from the plant-parasitic nematode Globodera pallida, which is a member of the nematode-specific fatty-acid- and retinol-binding (FAR) family of proteins but localizes to the surface of this species, placing it in a strategic position for interaction with the host. Recombinant Gp-FAR-1 was found to bind retinol, cis-parinaric acid and the fluorophore-tagged lipids 11-(dansylamino)undecanoic acid and dansyl-D,L-alpha-amino-octanoic acid. The fluorescence emission characteristics of the dansylated analogues indicated that the entire ligand enters the binding cavity. Fluorescence competition experiments showed that Gp-FAR-1 binds fatty acids in the range C(11) to C(24), with optimal binding at C(15). Intrinsic fluorescence ...

Cyst and root-knot nematodes show high levels of gross morphological similarity. This presents difficulties for the study of their ecology in natural ecosystems. In this study, cyst and root-knot nematode species, as well as some ectoparasitic nematode species, were identified using the second internal transcribed spacer (ITS2) sequence variation detected by polymerase chain reaction-single-strand conformational polymorphism (PCR-SSCP). The ITS2 region was sufficiently variable within the taxa investigated to allow species to be separated on the basis of minor sequence variation. The PCR primers used in this study were effective for 12 species with three genera within the Heteroderinae (Globodera pallida, G. rostochiensis, Heterodera arenaria/avenae, H. ciceri, H. daverti, H. hordecalis, PI. mani, PI. schachtii, H. trifolii, Meloidogyne ardenensis, M. duytsi and M. maritima). However, pathotypes of Globodera pallida and G. rostochiensis could not be distinguished. The method was tested at two ...

We characterized soil communities in the Mojave Desert across an elevation gradient. Our goal was to test the hypothesis that as soil quality improved with increasing elevation (due to increased productivity), the diversity of soil prokaryotes and nematodes would also increase. Soil organic matter and soil moisture content increased with elevation as predicted. Soil salinity did not correlate to elevation, but was highest at a mid-gradient, alluvial site. Soil nematode density, community trophic structure, and diversity did not show patterns related to elevation. Similar results were obtained for diversity of bacteria and archaea. Relationships between soil properties, nematode communities, and prokaryotic diversity were site-specific. For example, at the lowest elevation site, nematode communities contained a high proportion of fungal-feeding species and diversity of bacteria was lowest. At a high-salinity site, nematode density was highest, and overall, nematode density showed an unexpected, positive

In a PCR with degenerate primers encoding highly conserved amino acids within ornithine decarboxylases (ODCs) of several organisms, a fragment of the ODC gene of the free-living nematode Panagrellus redivivus was isolated. Northern blot analysis revealed a single 1.7 kb transcript in a mixed-stage population of animals. From this RNA source, a cDNA library was constructed and screened with the PCR fragment. Several cDNA clones were isolated, one of which encodes the complete 435-amino-acid ODC enzyme with a calculated molecular mass of 47.1 kDa. The P. redivivus ODC possesses 126 of the 136 highly conserved amino acids in the enzymes from fungi, invertebrates and vertebrates. Functional amino acids are conserved, suggesting that the two active sites of the P. redivivus ODC are formed at the interface of a homodimer, as described for mammalian ODCs. ...

Caenorhabditis elegans has been used as a host for the study of bacteria that cause disease in mammals. However, a significant limitation of the model is that C elegans is not viable at 37 degrees C. We report that the gonochoristic nematode Panagrellus redivivus survives at 37 degrees C and maintains its life cycle at temperatures up to and including 31.5 degrees C. The C elegans pathogens Pseudomonas aeruginosa, Salmonella enterica, Staphylococcus aureus, but not Yersinia pseudo tuberculosis, reduced P. redivivus lifespan. Of four strains of Burkholderia multivorans tested, one reduced P. redivivus lifespan at both temperatures, one was avirulent at both temperatures and two strains reduced P. redivivus lifespan only at 37 degrees C. The mechanism by which one of these strains killed P. redivivus at 37 degrees C, but not at 25 degrees C, was investigated further. Killing required viable bacteria, did not involve bacterial invasion of tissues, is unlikely to be due to a diffusible, bacterial ...

Root-knot nematodes transform vascular host cells into permanent feeding structures to withdraw nutrients from the host plant. Ecotypes of Arabidopsis thaliana can display large quantitative variation in susceptibility to the root-knot nematode Meloidogyne incognita, which is thought to be independent of dominant major resistance genes. However, in an earlier genome-wide association study of the interaction between Arabidopsis and M. incognita we identified a quantitative trait locus harboring homologs of dominant resistance genes but with minor effect on susceptibility to the M. incognita population tested. Here, we report on the characterization of two of these genes encoding the TIR-NB-LRR immune receptor DSC1 (DOMINANT SUPPRESSOR OF Camta 3 NUMBER 1) and the TIR-NB-LRR-WRKY-MAPx protein WRKY19 in nematode-infected Arabidopsis roots. Nematode infection studies and whole transcriptome analyses using the Arabidopsis mutants showed that DSC1 and WRKY19 co-regulate susceptibility of Arabidopsis to M.

What determines host specificity in hyperspecialized plant parasitic nematodes? | BMC Genomics | Full TextWhat determines host specificity in hyperspecialized plant parasitic nematodes? | BMC Genomics | Full Text
In hyperspecialized parasites, the ability to grow on a particular host relies on specific virulence factors called effectors. These excreted proteins are involved in the molecular mechanisms of parasitism and distinguish virulent pathogens from non-virulent related species. The potato cyst nematodes (PCN) Globodera rostochiensis and G. pallida are major plant-parasitic nematodes developing on numerous solanaceous species including potato. Their close relatives, G. tabacum and G. mexicana are stimulated by potato root diffusate but unable to establish a feeding site on this plant host. RNA sequencing was used to characterize transcriptomic differences among these four Globodera species and to identify genes associated with host specificity. We identified seven transcripts that were unique to PCN species, including a protein involved in ubiquitination. We also found 545 genes that were differentially expressed between PCN and non-PCN species, including 78 genes coding for effector proteins, which

Coupling Soybean Cyst Nematode Damage to CROPGRO-Soybean by J. Fallick, W. D. Batchelor et al.Coupling Soybean Cyst Nematode Damage to CROPGRO-Soybean by J. Fallick, W. D. Batchelor et al.
The soybean cyst nematode (SCN) Heterodera glycines Ichinohe is responsible for substantial economic losses in soybean (Glycine max L. Merr.) production throughout the U.S. Results from past efforts to quantify the severity of crop damage resulting from SCN are often subject to variable experimental conditions resulting from differences in weather, soil type, and cultivar. Because of the difficulty in accounting for these variables, a process-oriented crop growth simulation model was chosen as a platform for studying the dynamics of SCN damage and for transferring knowledge between crop production scenarios. The objective of this study was to develop and evaluate hypotheses for coupling SCN damage to the process-oriented crop growth model CROPGRO-Soybean. A monomolecular function was used to relate daily SCN damage to initial population density of SCN eggs. The equation was incorporated into the crop model in order to test two hypotheses of how SCN damage occurs. The first hypothesis was that SCN reduce

Infection by plant-parasitic nematodes (PPN) reduces global agricultural output by 10-15%. For rice alone this loss represents a commercial value of $35bn. All crops are affected to some degree, and the impact on subsistence farmers can be especially dire. The most pernicious PPN are highly adapted for life within plant roots. Some, such as the cyst (Globodera and Heterodera spp.) and root-knot nematodes (RKN: Meloidogyne spp.) establish a permanent feeding site by usurping host developmental circuitry. Others, including the lesion nematode (Pratylenchus spp.) function essentially as migratory herbivores. Understanding the molecular basis underpinning these distinct plant-nematode interactions is a key objective of the PPN research community.. The development of genetic tools for helminths has proven a challenge, largely because of the obligate, parasitic life stages within the host. For ethical and technical reasons, such barriers are much lower for PPN. Thus, we exploited M. haplas small ...

Soybean Cyst Nematodes are a recurring parasite that can drastically afflict yield. Further understanding of the interaction between the pest and its soybean host is essential to working towards increased plant resistance. Utilizing current molecular biology techniques, the plant response to parasitical exposure was analyzed, focusing on the effect on gene expression due to the presence and damage caused by the nematode, homozygous screening and western blot was also used to determine the genetic change in the samples. Through observing the stages of growth of the plant in conjunction with exposure to nematodes, affected phenotype of the plant samples was also observed in progressive stages.

Root-Knot Nematode | Plant Disease Diagnostics ClinicRoot-Knot Nematode | Plant Disease Diagnostics Clinic
Appearance: Root-knot nematodes are about one-tenth the size of a pinhead and are typically embedded inside roots. They are impossible to see with the naked eye. Juvenile root-knot nematodes (both males and females), as well as adult males, are vermiform (i.e., worm-shaped) and live in the soil. Adult females are spherical in shape and live inside roots. Both males and females possess a thin, tube-like structure called a stylet that they use for penetrating root tissue.. Symptoms and Effects: When root-knot nematodes enter roots, they release chemicals that cause nearby root cells to enlarge. This leads to the formation of swollen, distorted areas in roots known as galls or knots. The number and size of galls varies depending on plant species and cultivar, and the number of root-knot nematodes in the soil. On some hosts (e.g., grasses) root swelling can be very difficult to detect. Nematode feeding interferes with proper root function (e.g., water and nutrient movement). Thus infected plants may ...

Rhizobial-Legume Symbiosis and Root Knot Nematode Parasitism: Common Signal Transduction Pathways in LegumesRhizobial-Legume Symbiosis and Root Knot Nematode Parasitism: Common Signal Transduction Pathways in Legumes
Nodulation is an ecologically and economically important plant phenomenon, in which the symbiosis between plants from the family Fabaceae and the bacterial genera rhizobia results in the development of nitrogen fixing nodules on host plant roots. The rhizobia-plant interaction is initiated by Nod factors, which are produced by species-specific rhizobia; Nod factor alone is necessary and sufficient to produce many of the initial responses including ionic fluxes, root hair deformation, changes in gene expression, cortical cell differentiation and generation of a pseudo nodule. Giant cell formation by plant pathogenic root knot nematodes (RKN) invokes host genes necessary for nitrogen-nodule formation. Specific transcription regulators, cytokinin response pathways and early nodulation genes are induced in the nematode feeding site and rhizobia induced nodules. This suggests that nodulation by rhizobia and RKN infection may share host signal transduction and/or developmental pathways. The presence ...

Field resistance to cyst nematode (SCN) race 3 (Heterodera glycines I.) in soybean [Glycine max (L.) Merr.] cv Forrest is conditioned by two QTLs: the underlying genes are presumed to include Rhg1 on linkage group G and Rhg4 on linkage group A2. A population of recombinant inbred lines (RILs) and two populations of near-isogenic lines (NILs) derived from a cross of Forrest × Essex were used to map the loci affecting resistance to SCN. Bulked segregant analysis, with 512 AFLP primer combinations and microsatellite markers, produced a high-density genetic map for the intervals carrying Rhg1 and Rhg4. The two QTLs involved in resistance to SCN were strongly associated with the AFLP marker EATGMCGA87 (P = 0.0001, R2 = 24.5%) on linkage group G, and the AFLP marker ECCGMAAC405 (P = 0.0001, R2 = 26.2%) on linkage group A2. Two-way analysis of variance showed epistasic interaction (P = 0.0001, R2 =16%) between the two loci controlling SCN resistance in Essex × Forrest recombinant inbred lines. Considering

Anderson et al. [51,52] reported that the presence of localized bacterial food source (Escherichia coli) acting as a chemo-attractant caused the movements of the nematode Caenorhabditis elegans on a homogeneous layer of nutrient agar in a Petri dish to become straighter and more directed. These movements approximate to a straight line, which is, of course, the shortest possible route to the source of the chemo-attractant. The results of our numerical simulations build upon the study of Anderson et al. [51,52] and provide a provocative answer to the question of how plant-parasitic nematodes locate distant sources of chemo-attractant. They indicate that chemotaxis can take a nematode to the source of a pure chemo-attractant by the shortest, most direct route through the labyrinth of air-filled or water-filled channels within a soil through which the attractant diffuses. Previously, this remarkable consequence of chemotaxis had gone unnoticed. Searching strategies and maze-solving algorithms are ...

The researches on the biological control of nematodes with nematophagous fungi has been intensified in recent years. The knowledge of the ecological conditions for the growth and sporulation of these fungi is a prerequisite for attainment of pure cultures needed to attend the demand for formulation of these organisms. With the objective to evaluate the micelial growth and sporulation of Arthrobotrys musiformis and A. oligospora in two environments (B.O.D at 25 +/- 1 degrees C and the environment of the Laboratory), 20 cultures media prepared with common materials found in the communities and industrialized media such as mycological agar, PDA and CMA were evaluated. The media were tested in Petri dishes, being the micelial growth of the fungi evaluated daily, during six days. The measured sporulation at the end of the experiment was done by estimation of the number of conidia/Petri dish. The experiment was carried out in a random design following a factorial arrangement of 20 x 2 x 2, ...

Crop Sci 2006 46:2325-2326. Interpretive Summary: Technical Abstract: Soybean germplasm line D99-2065 was released in October 2003. The objective was to provide private and public soybean breeders with a parent to develop high yielding, multiple pest resistant cultivars. Phytophthora rot (PR) and soybean cyst nematode (SCN) continue to be serious yield-limiting diseases of soybean. D99-2065 is a product of a backcrossing program to transfer the Rps1-b gene into a Bedford background. This line has value as a parent because of its resistance to PR and races 3 and 14 of the soybean cyst nematode. It also has value to the research community because it will expand the set of previous releases of PR-resistant lines which are near-isogenic to the cultivar Bedford. The reaction of 12 F3 plants was used to ...

Western corn rootworm, Diabrotica virgifera virgifera, is a pest that needs to be controlled with chemicals in the maize monoculture. The aim of this study was to examine the influence of insecticides on nematode communities in a maize field. Four soil treatments were used in this experiment: variant 1 - a granular application with tefluthrin (199.5 g a.i./ha); variant 2 - a granular application with clothianidin (110 g a.i./ha); variant 3 - a seed treatment with clothianidin (1.25 μg a.i/seed); and control - a maize field without insecticides.. During the investigated period, a total of 19 117 soil nematode individuals were captured and 9 orders, 33 genera and 37 species were identified. Acrobeloides nanus, Cephalobus persegnis, Eucephalobus striatus and Basiria gracilis were the dominant species, accounting for 48 % of the total number of individuals. The mean abundance and species diversity index were significantly lower for variant 2. Bacterial feeders were the dominant trophic group for ...

Above: A nematode seen under a microscope. UF/IFAS photo by Tyler Jones.. A parasite is an organism that lives on or inside of another organism, weakening its host but usually not killing it. This feature distinguishes it from a parasitoid, which typically does kill its host.. Words related to parasite include parasitic (adjective), parasitism (noun) and parasitize (verb). Obligate parasitism occurs when an organism can only survive by its parasitic relationships with another organism.. Plant-parasitic nematodes are one example of a parasitic bug. These nematodes are very small and may only be visible with a microscope. Like other nematodes, plant-parasitic nematodes live in the soil, where they feed on plants.. Many of these parasitic nematodes attack plants from the outside with a spear-like body part called a stylet. Because of this behavior we call them ectoparasites, parasites that live on the outside of their host.. Other nematodes live inside a plant, making them endoparasites. Root-knot ...

In Brazil, as the soybean crop expands the losses caused by nematodes as well as its incidence in producing areas have increased. Therefore, this work aimed to develop a non-genetically modified soybean which combines desirable traits as the root-knot nematode resistance, early-maturity, high seed yielding, and high oil and protein contents. Consequently, seeds (F2) derived from the double-crossing between (Guarani x Sambaiba) x (M Soy 6101 x Conquista) were bulked to grow the F3 generation. Following generations were advanced by the SSD method of breeding until F6. Thus, plants showing superior characteristics were planted separately to perform progeny tests and then advanced breeding lines were thoroughly tested and compared to standards in representative environments across several locations in the Midwestern region in Brazil. As a result, we developed an early-soybean with cycle-length of 107 days; usually cycles range from 90 to 160 days. It presents desirable traits as high yield (3677 kg ...

SOY006 - Disease Resistance in Selected Soybean Varieties
Soybean cyst nematode (SCN) is the most serious soybean pathogen in North Carolina. Since its discovery in North Carolina (and the United States) in 1954, it has spread to all counties in the Coastal Plain, Tidewater, and some Piedmont counties with large soybean acreages. Severe yield loss caused by this pest is especially common in sandy coastal plain soils. SCN, however, is not restricted to any soil type and often causes significant soybean yield losses which may go unnoticed. Races of Soybean Cyst Nematode Field populations of SCN are characterized as races (numbered 1 through 16). A race designation of cyst nematode is an indication of a field populations ability to reproduce on each of several soybean varieties or lines. Knowing the race of cyst nematode in a given field can assist the grower in making decisions about which resistant varieties should be used. For example, if a field has race 1 or 3, then selection of a variety resistant to these races would be the appropriate choice. ...

Model Organisms in Molecular Biology and Biomedical Research - Biokemisk Forening
Nematode models in evolution and development.. Ralf J. Sommer, Max-Planck Institute for Developmental Biology, Tübingen, Germany. [email protected] Nematodes are the largest animal phylum that is best characterized by species richness, numerical abundance and ecological omnipresence. Comprising of free-living as well as parasitic species, several nematodes became important model systems in modern biology. Most importantly, Caenorhabditis elegans has been at the forefront of research in modern developmental biology, genetics, neurobiology and genomics. After reviewing the state of the art research platforms in C. elegans I will expand to the possibility to develop other nematode species as comparative models for development and evolution. We have developed the distantly related Pristionchus pacificus as a model system in development, but also ecology and evolutionary biology. Among other topics, comparative evolutionary developmental biology (evo-devo) can indicate the conservation ...

Nematode Genome Announcement: A Draft Genome for Rice Root-Knot Nematode, Meloidogyne graminicolaNematode Genome Announcement: A Draft Genome for Rice Root-Knot Nematode, Meloidogyne graminicola
Rice is the second most important food crop in the world after corn based on the total production. In 2016, rice was cultivated in 161.1 million ha area, and the global production was 482 million metric tons (World Rice Statistics, International Rice Research Institute, Manila, Philipines, http://ricestat.irri.org:8080/wrsv3/entrypoint.htm). The rice root-knot nematode, Meloidogyne graminicola, has emerged as a devastating pest of rice in South-East Asia (Dutta et al., 2012; Mantelin et al., 2016), where it is highly damaging under upland, rainfed lowland (Prot et al., 1994) and irrigated (Netscher and Erlan, 1993) cultivation conditions. Severe M. graminicola infection is known to cause 100% damage to the rice nursery. Here, we report the sequencing and assembly of the genome of M. graminicola IARI strain. This resource would help researchers investigate and understand the unique biology of this nematode and discover new strategies for its management.. Considering the ~30 Mb genome size of M. ...

Supplementary MaterialsTable S1: Gene Ontology mappings for clusters. expansin proteins. Introduction Expressed sequence tags (ESTs) have proven to be one of the most rapid routes to gene discovery of any organism for which a cDNA library is available [1]. In addition, large-scale EST analysis can be used to estimate gene expression levels in specific life stages or tissues and are useful tools for annotation of genome sequences [1], [2]. EST analysis has been widely applied to study the biology of nematodes. Over 1.5 million ESTs from more than 63 species, including free-living nematodes, animal-parasitic and plant-parasitic species are available in dbEST (GenBank, 1 October 2012). To date, over 125,000 EST sequences from twenty different plant-parasitic nematodes are in dbEST. This information is of great significance for studying nematode biology, especially for the identification of effectors. Plant-parasitic nematode effectors, defined Maraviroc distributor here as proteins secreted by the ...

Family Report for: Carb B Nematoda
The ges-1 gene codes for a non-specific carboxylesterase that is normally expressed only in the intestine of the nematode Caenorhabditis elegans. In the current paper, we describe the cloning and characterization of the ges-1 gene from C. elegans, as well as the homologous gene from the nematode Caenorhabditis briggsae. The ges-1 esterases from the two nematodes are 83% identical at the amino acid level and contain regions of significant similarity to insect and mammalian esterases; these conserved regions can be identified with residues believed to be necessary for esterase function. The ges-1 mRNAs from both C. elegans and C. briggsae are trans-spliced. The coding regions, the codon bias and the splicing signals of the two ges-1 genes are quite similar and most (6/7) of the intron positions are retained precisely. Yet, the flanking sequences of the two ges-1 genes appear to have diverged almost completely. For example, the C. elegans ges-1 5-flanking region (as well as several introns) ...

Some nematodes of the genus Rhabdias Stiles et Hassall, 1905 (Nematoda: Rhabdiasidae) parasitising amphibians in French GuianaSome nematodes of the genus Rhabdias Stiles et Hassall, 1905 (Nematoda: Rhabdiasidae) parasitising amphibians in French Guiana
Based on material collected from Rhinella cf. margaritifera (Laurenti) and Rhi. marina (Linnaeus) (Anura: Bufonidae) during a parasite survey of the herpetofauna of French Guiana, updated descriptions of Rhabdias androgyna Kloss, 1971 and R. fuelleborni Travassos, 1926 are presented. In addition to metrical data, which may overlap in closely related species, emphasis is placed on qualitative characters. Rhabdias androgyna is distinguished by the unique presence of an outer and inner cephalic cuticular inflation, a shoulder-like broadening of the body at the anterior end, a wide and shallow buccal capsule (average buccal ratio 0.36) with serrated lumen in apical view, a prominent anterior dilatation of the oesophagus, and the presence of an additional posterior dilatation anterior to the oesophageal bulb. Characters that may help to differentiate R. fuelleborni from closely related species parasitising the Rhi. marina species group are the presence of six relatively uniform lips, and the division ...
