Factors influencing the sporulation and cyst formation of Aphanomyces invadans, etiological agent of ulcerative mycosis in Atlantic menhaden, Brevoortia tyrannus. (1/22)

Oomycete infections caused by Aphanomyces invadans occur in freshwater and estuarine fishes around the world. Along the east coast of the USA, skin ulcers caused by A. invadans are prevalent in Atlantic menhaden, Brevoortia tyrannus. From laboratory observations low salinities appear crucial to transmission of the pathogen. To better understand aspects of transmission, we characterized sporulation and cyst formation of secondary zoospores of two isolates of A. invadans at different salinities and temperatures. Sporulation occurred only at low salinities. At room temperature (ca. 20-22 C), using "pond water" augmented with artificial sea salts, the endemic strain WIC and the Thailand strain PA7 of A. invadans produced free-swimming secondary zoospores at salinities of 0, 1 and 2 psu (practical salinity unit = per thousand), but not at 4 psu or higher. Secondary zoospores of another species, ATCC-62427 (Aphanomyces sp.), were observed at 1, 2, 4 and 8 psu but not at 0 and 12 psu. Secondary zoospores of all three isolates, especially WIC, were abundant and motile 1-2 d postsporulation. Sporulation was temperature dependent and occurred over a relatively narrow range. No sporulation occurred at 4, 30 or 35 C for either WIC or PA7. For both strains zoospore production within 1-3 d after the initiation of sporulation was more prolific at 25 C than at 20 and 15 C. At 15 C production of zoospores was sustained over 11 d for WIC and 5 d for PA7. At room temperature single WIC secondary zoospores remained motile 12-18 h. Salinities exceeding 4 psu or vigorous shaking caused immediate cyst formation of WIC secondary zoospores. Exposure to menhaden tissue, but not tissues of other fishes to secondary zoospores (WIC), caused rapid (2 h) cyst formation. Cysts were capable of excysting when transferred to 1 psu water within 2-3 h of cyst formation. Cysts that had remained encysted in 6.5 psu for 24 h did not excyst when transferred to 1 psu water. Salinity and temperature requirements for sporulation indicate that juvenile menhaden must acquire infections during rain or in low salinity oligohaline waters.  (+info)

Molecular assays for detecting Aphanomyces invadans in ulcerative mycotic fish lesions. (2/22)

The pathogenic oomycete Aphanomyces invadans is the primary etiological agent in ulcerative mycosis, an ulcerative skin disease caused by a fungus-like agent of wild and cultured fish. We developed sensitive PCR and fluorescent peptide nucleic acid in situ hybridization (FISH) assays to detect A. invadans. Laboratory-challenged killifish (Fundulus heteroclitus) were first tested to optimize and validate the assays. Skin ulcers of Atlantic menhaden (Brevoortia tyrannus) from populations found in the Pamlico and Neuse River estuaries in North Carolina were then surveyed. Results from both assays indicated that all of the lesioned menhaden (n = 50) collected in September 2004 were positive for A. invadans. Neither the FISH assay nor the PCR assay cross-reacted with other closely related oomycetes. These results provided strong evidence that A. invadans is the primary oomycete pathogen in ulcerative mycosis and demonstrated the utility of the assays. The FISH assay is the first molecular assay to provide unambiguous visual confirmation that hyphae in the ulcerated lesions were exclusively A. invadans.  (+info)

Phenolic constituents of Celosia cristata L. susceptible to spinach root rot pathogen Aphanomyces cochlioides. (3/22)

Cochliophilin A (5-hydroxy-6,7-methylenedioxyflavone, 1), known as a host-specific attractant towards the zoospores of Aphanomyces cochlioides, a cause of root rot and damping-off diseases of Chenopodiaceae, was found in the Amaranthaceae plant, Celosia cristata, that is susceptible to the pathogen. The content of 1 in Celosia seedlings was quantified as 1.4 microg/g fresh weight. A new isoflavone, cristatein (5-hydroxy-6-hydroxymethyl-7,2'-dimethoxyisoflavone, 2), and five known flavonoids were also identified.  (+info)

Detection of Aphanomyces astaci in North American crayfish by polymerase chain reaction. (4/22)

We present a PCR based method to detect Aphanomyces astaci in North American crayfish. Primers were designed to specifically amplify parts of the internal transcribed spacer (ITS) regions and the 5.8 rRNA gene of A. astaci. A single round and a semi-nested assay were tested for their sensitivity and specificity. Specificity of the PCR assays was tested against several closely related Aphanomyces species, other Oomycetes and some non-A. astaci DNA that might be found in or on crayfish. The single round assay was fully specific against all DNA tested. In the semi-nested assay, cross-reaction was seen when the equivalent of 40,000 or more genomic units of A. invadans or A. frigidophilus were entered into the PCR reaction. The lower detection limit of both assays lies around 1 genomic unit of A. astaci. Investigation of various parts of the exoskeleton of 3 North American crayfish species revealed that for O. limosus and P. leniusculus the telson and soft abdominal cuticle yielded a positive PCR reaction most frequently. For the third species, Procambarus clarkii, only 1 individual tested positive, so no conclusion as to preferred infestation site(s) could be drawn.  (+info)

AphanoDB: a genomic resource for Aphanomyces pathogens. (5/22)

BACKGROUND: The Oomycete genus Aphanomyces comprises devastating plant and animal pathogens. However, little is known about the molecular mechanisms underlying pathogenicity of Aphanomyces species. In this study, we report on the development of a public database called AphanoDB which is dedicated to Aphanomyces genomic data. As a first step, a large collection of Expressed Sequence Tags was obtained from the legume pathogen A. euteiches, which was then processed and collected into AphanoDB. DESCRIPTION: Two cDNA libraries of A. euteiches were created: one from mycelium growing on synthetic medium and one from mycelium grown in contact to root tissues of the model legume Medicago truncatula. From these libraries, 18,684 expressed sequence tags were obtained and assembled into 7,977 unigenes which were compared to public databases for annotation. Queries on AphanoDB allow the users to retrieve information for each unigene including similarity to known protein sequences, protein domains and Gene Ontology classification. Statistical analysis of EST frequency from the two different growth conditions was also added to the database. CONCLUSION: AphanoDB is a public database with a user-friendly web interface. The sequence report pages are the main web interface which provides all annotation details for each unigene. These interactive sequence report pages are easily available through text, BLAST, Gene Ontology and expression profile search utilities. AphanoDB is available from URL: http://www.polebio.scsv.ups-tlse.fr/aphano/.  (+info)

Aphanomyces euteiches is an oomycete pathogen with a broad host-range on legumes that causes devastating root rot disease in many pea-growing countries and especially in France. Genetic resistance is a promising way to manage the disease since consistent QTL controlling partial resistance have been identified in near isogenic lines of pea. However, there are still no resistant pea varieties cultivated in France. This study aimed to evaluate the phenotypic and genetic diversity of A. euteiches populations from the major pea-growing regions in France. A collection of 205 isolates, from soil samples collected in infested pea fields located in five French regions, was established and genotyped using 20 SSR markers. Thirteen multilocus genotypes were found among the 205 isolates which displayed a low genotypic richness (ranged from 0 to 0.333). Two main clusters of isolates were identified using PCoA and STRUCTURE, including a predominant group comprising 88% of isolates and another group representing 12% of

Aphanomyces were initially known as parasites of plants, small invertebrates and crustaceans. Probably the first case reported of fish being infected by Aphanomyces species was from guppy (Poecilia reticulata), Maxican blind cave (Astyanax mexicanus), a hybrid of platy (Platypoecilus maculatus) and swordtail (Xiphophorus hellerii) [26]. Aphanomyces, along with other oomycetes, e.g. Saprolegnia species have caused severe losses to aquaculture industry till to-date. From an evolutionary point of view it seems that the pathogenesis of plant oomycetes is mediated by effectors, while host invasion by animal pathogenic oomycetes is facilitated by expansion of proteases [24]. Many infectious microorganisms require proteases for replication or use proteases as virulence factors to cross proteinaceous barrier within the host. Proteases secreted by the fish oomycete Saprolegnia parasitica are suggested to be involved in attacking the host tissue and paving the way for further penetration of the fungus ...

Fifty-four isolates of various fish-pathogenic and saprophytic fungi were characterized in terms of their susceptibility to three antibiotics (penicillin, streptomycin and oxolinic acid), three fungicides (malachite green, hydrogen peroxide and sodium chloride) and three disinfectants (an iodophore, sodium hypochlorite and a solution of peracetic acid and hydrogen peroxide). Aphanomyces invaderis, the fungus associated with the Asian fish disease epizootic ulcerative syndrome (EUS); other Aphanomyces isolates from the similar conditions redspot disease (RSD) and mycotic granulomatosis (MG); and the crayfish plague fungus, Aphanomyces astaci, were more sensitive to most of the chemical agents than the other fungi tested. Two compounds currently being considered for use in aquaculture, hydrogen peroxide and Proxitane 0510, are shown here to have some potential for fungicidal treatments and disinfection, respectively. The implications of this study with respect to the isolation, treatment and ...

Some oomycetes species are severe pathogens of fish or crops. As such, they are responsible for important losses in the aquaculture industry as well as in agriculture. Saprolegnia parasitica is a major concern in aquaculture as there is currently no method available for controlling the diseases caused by this microorganism. The cell wall is an extracellular matrix composed essentially of polysaccharides, whose integrity is required for oomycete viability. Thus, the enzymes involved in the biosynthesis of cell wall components, such as cellulose and chitin synthases, represent ideal targets for disease control. However, the biochemical properties of these enzymes are poorly understood, which limits our capacity to develop specific inhibitors that can be used for blocking the growth of pathogenic oomycetes.. In our work, we have used Saprolegnia monoica as a model species for oomycetes to characterize two types of domains that occur specifically in oomycete carbohydrate synthases: the Pleckstrin ...
Parasite of the Day: September 28 - Aphanomyces invadansParasite of the Day: September 28 - Aphanomyces invadans
Aphanomyces invadans is a highly pathogenic oomycete fungi which infects the Atlantic menhaden Brevoortia tyrannus and many other species of fish from around the world. This water mould has been implicated in massive fish kills in North Carolina, resulting in hundreds of thousands of dead fish. On average, an infection resulting from less than 10 zoospores (the infective stage of this fungi) is enough to kill a fish, and even infection by just a single zoospore can result in ulcerous lesions that can lead to mortality. Fish infected with the fungi develops ulcerous lesions which ultimately lead to extensive tissue necrosis. This fungus develops extremely quicky, doubling its hyphal mass every ten days, and it is also highly invasive, extending its hyphae into various tissues including the liver, kidneys and spinal cord of the fish host. Interestingly, A. invadans outbreaks are associated with high rainfall. This is likely due to the fact that this water mould has a low salinity tolerance and ...

EN ISO 10273 method for the detection of pathogenic Yersinia enterocolitica in foods was validated in the project Mandate M/381 funded by European Commission. A total of 14 laboratories from five European countries participated in the interlaboratory study (ILS) organized during 2013 and 2014. Before the ILS, the method was revised by an international group of experts and the performance of the revised method was assessed in an ILS study. The results are published as a part of the standard EN ISO 10273 revision. The study included three rounds with different sample types; raw milk, iceberg lettuce and minced meat, inoculated with a low and high level of pathogenic Y. enterocolitica strains representing major pathogenic bioserotypes 4/O:3 and 2/O:9. The homogeneity and stability of the samples were verified before dispatching them to the laboratories. The results demonstrated the method sensitivity of 96% in raw milk, 97% in minced meat, and 98% in lettuce at high inoculation level of pathogenic ...

Recent studies on the root proteome of Medicago truncatula (Gaertn.) showed an induction of pathogenesis-related (PR) proteins of the class 10 after infection with the oomycete pathogen Aphanomyces euteiches (Drechs.). To get insights into the function of these proteins during the parasitic root-microbe association, a gene knockdown approach using RNAi was carried out. Agrobacterium rhizogenes-mediated transformation of M. truncatula roots led to a knockdown of the Medicago PR10-1 gene in transgenic in vitro root cultures. Proteomic analyses of the MtPr10-1i root cultures showed that MtPr10-1 was efficiently knocked down in two MtPr10-1i lines. Moreover, five additional PR-10-type proteins annotated as abscisic acid responsive proteins (ABR17s) revealed also an almost complete silencing in these two lines. Inoculation of the root cultures with the oomycete root pathogen A. euteiches resulted in a clearly reduced colonization and thus in a suppressed infection development in MtPr10-1i roots as ...

PDDC - Help in Identifying Plant DiseasesPDDC - Help in Identifying Plant Diseases
What is Aphanomyces root rot of alfalfa? Aphanomyces root rot (ARR) is a serious disease of both recently seeded alfalfa and established alfalfa stands. ARR can cause severe yield reductions in affected alfalfa fields. Variations of the disease also occur on many other legumes (including soybean, snap bean, faba bean, red kidney bean, pea, red clover, and white clover) and can cause significant losses in these crops as well.. What does Aphanomyces root rot look like? Typically alfalfa emergence is not dramatically affected by the ARR, but symptoms appear shortly after seedlings emerge. Young plants appear stunted and yellow and may eventually die. The root systems of affected seedlings are smaller than normal and what roots remain, appear gray and water-soaked. Older alfalfa plants suffering from ARR also tend to be stunted and yellow. They may have a well-developed tap root, but typically relatively few smaller, fine roots. Oftentimes growers realize they have a problem with ARR when they ...

Two alfalfa clones have been identified that differ in resistance to lodging. The lodging susceptible and lodging resistant clones and the F1 resulting from this cross was crossed with each parent to produce two different backcross populations. Replicated clones of each parent, F1 and backcross plants will be produced in the greenhouse. The replicated clones will be transplanted into three different field locations, two in WA and one in WI. DNA from the parents, F1 and BC1s will be screened for the presence of sequence related amplified polymorphisms (SRAPs) using protocols optimized for amplifying SRAP markers from alfalfa. Resistant and susceptible bulk DNA extracts will be subjected to bulk segregant analysis with SRAP primers to identify candidate polymorphic loci associated with resistance to lodging. Candidate markers will be clustered into a linkage group map. Molecular markers will be developed that discriminate unambiguously between Race 1 and Race 2 of Aphanomyces euteiches that cause ...

Aphanomyces astaci spreads by means of motile zoospores released from the mature filaments in infected crayfish. The zoospores are attracted to crayfish cuticle, and filaments penetrate immediately. Zoospores can remain motile for up to 3 days and cysts survive for 2 weeks (in distilled water).4 Zoospores can re-encyst three times if they do not encounter a host. It is recommended to wait three months before attempting to re-stock waters in which crayfish have been killed by crayfish plague to allow all zoospores to die out.. Historically, crayfish plague spread to Europe with infected American crayfish brought and then distributed for culture and fishery purposes. The American crayfish are tolerant of infection and can remain carriers for life. Crayfish plague is also spread via contaminated fishing equipment or zoospores in water.5. American crayfish, including red swamp crawfish (Procambarus clarkii) and signal crayfish (Pacifastacus leniusculus), can carry crayfish plague and may exhibit ...

Abstract Intra- and inter-specific competition for shelter, in relation to prior residence, sex differences, and body-size effects, was studied in the laboratory to assess the potential impact of the alien crayfish species Pacifastacus leniusculus on the endangered Japanese endemic crayfish species Cambaroides japonicus. The resident was placed in an aquarium, which contained a single shelter of preferred size for both C. japonicus and P. leniusculus. After 24 h, the intruder was introduced into the aquarium. In the experiments using different sex pairs of crayfish of approximately equal size, male residents had a significant prior residence effect against female intruders in both crayfish species in the intraspecific contests. However, residents of P. leniusculus dominated C. japonicus regardless of the sex in interspecific contests. In experiments using male crayfish pairs of different sizes, larger individuals had more successful possessions of the shelter against smaller individuals regardless of

Menhaden Fisheries Coalition Thanks ASMFC For Adopting Best Science on Menhaden Ecological Reference PointsMenhaden Fisheries Coalition Thanks ASMFC For Adopting Best Science on Menhaden Ecological Reference Points
WASHINGTON, Nov. 14, 2017 (GLOBE NEWSWIRE) -- The Menhaden Fisheries Coalition (MFC) thanks the Commissioners of the Atlantic States Marine Fisheries Commission (ASMFC) Atlantic Menhaden Management Board for following the best available science in setting reference points for Atlantic menhaden.. As part of Amendment 3 to the Atlantic Menhaden Intestate Fishery Management Plan (FMP), the Commission voted 16-2 to continue current management measures for Atlantic menhaden until its Biological Ecological Reference Points (BERP) Workgroup finishes developing menhaden-specific ecological reference points (ERPs). These ERPs are supported by the MFC, and would manage menhaden based on its role in the ecosystem as forage for predator species.. The best science shows that managing forage fish according to general biological principals, as advocated by various environmental and sportfishing groups, is not the correct approach. Earlier this year, Dr. Ray Hilborn and a team of top fishery scientists released ...

Atlantic menhaden (Brevoortia tyrannus) plays an important role in linking production from lower trophic levels to diverse marine predators and supporting the largest commercial fishery on the U.S. east coast. A significant management controversy has arisen because of uncertainties over their movement into and out of the Chesapeake Bay and the size or age-dependent vulnerability of fish to the commercial fishery. A landmark mark-recapture study of Atlantic menhaden was conducted during the 1960s-70s, which allows estimation of movement rates. Over one million menhaden were tagged, and over 200,000 tags were recovered, but the data were never fully analyzed. Using these data, this study will obtain estimates of migration rates and selectivity patterns, develop maps of the menhadens range, and obtain estimates of the impact of the spatial distribution of the fishery on menhaden. These results will substantially improve our knowledge of menhaden population dynamics (migration and mortality rates), ...

Purpose and background informationPurpose and background information
These root-rotting oomycetes (Pythium, Phytophthora, Aphanomyces) are the reason we use sterile potting mixes for houseplants and for starting vegetable and flower transplants, rather than taking soil directly from our yards or gardens. Since oomycetes like water-logged soils, we also use pots with holes in the bottom to promote good drainage and healthy plant roots.. Other important plant diseases caused by oomycetes include downy mildews and the white rusts, which are diseases of aboveground plant parts, e.g., leaves, shoots, and fruits. Both downy mildews (e.g., Peronospora, Plasmopara) and white rusts (Albugo) are caused by obligate parasites, that cannot be grown in culture.. ...

Fish oil made from menhaden (Brevoortia tyrannus) can be used as a dietary supplement for the presence of high levels of the long-chained omega-3 fatty acids, viz. epentaenoic and docosahexanoic. In this work, for the first time, two different multidimensional approaches were developed and compared, in terms of peak capacity, for triacylglycerol characterization. In particular, silver ion chromatography with a silver-ion column and non-aqueous reverse-phase liquid chromatography with a C18 column were tested in both comprehensive (stop-flow) and off-line modes. The use of mass spectra attained by atmospheric pressure chemical ionization for both LC approaches, and the fatty acids methyl esters profile of menhaden oil obtained by gas chromatography analysis, greatly supported the elucidation of the triacylglycerol content in menhaden oil. The off-line approach afforded a better separation and, thus, higher peak capacity to allow identifying and semiquantifying more than 250 triacylglycerols. Such a huge

1. The closer and opener muscles in the third walking legs of the three crayfish Pacifastacus leniusculus, Procambarus clarkii and Astacus leptodactylus are composed of fibres which differ in histochemistry, electrophysiology and morphology. Three major groups of fibres (A, B and C) were distinguished. 2. Group A fibres react weakly to histochemical stains for myofibrillar ATPase (mATPase) activity characteristic of fibres with slow shortening speeds. In the opener muscle, they are innervated by the opener excitor (OE) and the specific opener inhibitor (OI). In the closer muscle, group A fibres are innervated by the common inhibitory neurone (CI) in addition to single (slow closer excitor, SCE) or double excitatory (SCE and fast closer excitor, FCE) innervation. Group A fibres have the largest excitatory junction potentials (EJPs), the longest membrane time constants (tau) and the longest sarcomeres. They are located at the very distal and proximal ends of both muscles. 3. Group B fibres show ...

Fish Shrinking as Ocean Temperatures RiseFish Shrinking as Ocean Temperatures Rise
Menhaden make up about one-half of the Atlantic and Gulf of Mexico fish harvest and had a dockside value of about $129 million in 2013. They are coastal species that spawn offshore and move to estuaries where juveniles grow to one- and two-year old fish. The air and sea surface temperature off the Atlantic coast and the Gulf of Mexico has steadily increased, especially in estuaries, where heat exchange occurs efficiently between air and sea. Adult menhaden return offshore where they are harvested with purse seine nets. Menhaden are a significant food source for birds, seals, whales, striped bass and other animals. Therefore, the consequences of Menhaden shrinking in body size extend throughout the food web. Turner calculated the weight and length changes of these fish using data collected by the National Marine Fisheries Service. From 1955 to 2008, about 495,000 Atlantic menhaden were collected by the agency. From 1964 to 2010, about 510,000 Gulf of Mexico menhaden were collected. The data shows ...
Interdisciplinary, My Dear Watson | apricotpieInterdisciplinary, My Dear Watson | apricotpie
When I enrolled in a course in Fishery Biology, I was under the impression that it would exclusively study, well, fish. While it might emphasize fish populations and their environments, I assumed ichthyology would be the subject of focus.. I was mistaken. But not in a bad way. While the first two chapters outlined the biology and diversity of fish, the rest of the course dealt with fish as an economic resource and environmental player. I distinctly recall spending time considering different styles of fish hooks, their effects on bycatch, and whether they reduced the amount of target species the fisherman actually wanted to catch.. It turns out that Fishery Biology is the study of fish stocks - fishes caught for purposes of human consumption. Everyone picked a different species to study throughout, and we got to evaluate each others work. One such student project was on the Atlantic Menhaden - a small, oily-fleshed type of fish caught to be sold as bait or as an ingredient in dog food. However, ...

Out of a total of fifty-three fragments he located twenty-nine; the twenty-four which he left unlocated are mere scraps, averaging six-and-a-half letters (maximum twelve, minimum two), with about a third of their letters represented by ambiguous and sometimes minimal remains. This chapter summarizes the following: (a) hitherto unknown, and possibly true: 524, 528; (b) hitherto unknown, and evidently false: 109, 438; (c) agreeing with a true variant against a false: 294, 461, 525; (d) agreeing with the medieval tradition in a reading which is commonly corrected: 200.

Dangerous lung worms found in people who eat raw crayfishDangerous lung worms found in people who eat raw crayfish
The recent infections, which occurred in patients ages 10-32, have prompted the Missouri Department of Health & Senior Services to issue a health advisory alerting doctors across the state. The department also printed posters warning people not to eat raw crayfish and placed them in campgrounds and canoe rental businesses near popular Missouri streams. Thoroughly cooking crayfish kills the parasite and does not pose a health risk.. Paragonimiasis is far more common in East Asia, where many thousands of cases are diagnosed annually in people who consume raw or undercooked crab that contain Paragonimus westermani, a cousin to the parasite in North American crayfish.. While the U.S. Centers for Disease Control and Prevention has an antibody test to identify Paragonimus westermani infection, the test is not sensitive for patients with P. kellicotti parasite, and this makes diagnosis a real challenge. Diagnostic clues include elevated levels of white blood cells called eosinophils. These cells ...

Hemocytes (blood cells) are important in the immune defense against pathogens in invertebrates. In crusteacean, the hemocytes and plasma components mount a strong innate immune response against different pathogens including bacteria and virus. This thesis is aimed to identify marker proteins associated with development of different hemocyte types, and to find a protein involved in the phenoloxidase-induced melanization and other innate immune reactions in freshwater crayfish Pacifastacus leniusculus. In crustaceans, the hemocytes are produced and partly differentiated in the hematopoietic tissue (Hpt) before they are released into the hemolymph circulation. To investigate the connection between semigranular cells, granular cells and precursor cells in Hpt of P. leniusculus and possibly also in other crustaceans, two-dimensional gel electrophoresis (2-DE) coupled with mass spectrometry (MS) analysis was used to identify specific proteins expressed in different hemocytes. The specific expression ...

Atlantic menhaden are found in estuarine and coastal waters from northern Florida to Nova Scotia, and serve as prey ( food ) for many fish, sea birds and marine mammals. Adult and juvenile menhaden form large, near-surface schools, primarily in estuaries and near-shore ocean waters from early spring through early winter. By summer, menhaden schools stratify by size and age along the coast, with older and larger menhaden found farther north. During fall through early winter, menhaden of all sizes and ages migrate south around the North Carolina capes to spawn.. Sexual maturity begins just before age three, with major spawning areas from the Carolinas to New Jersey; the majority of spawning occurs primarily offshore ( 20-30 miles ) during winter. Buoyant eggs hatch at sea, and larvae are carried into estuarine nursery areas by ocean currents. Larvae change into juveniles in estuaries where they spend most of their first year of life, migrating to the ocean in late fall. Adult and juvenile menhaden ...

There is firstly an analysis of the Adept, which enables him to calculate his course of action. He can decide what must be banished, what purified, what concentrated. He can then concentrate his will upon its one essential element, over-coming its resistance - which is automatic, like a physiological reflex - by destroying inhibitions through his ego-overwhelming enthusiasm. 1 The other half of the work needs no such complex effort; for his Angel is simple and unperplexed, ready at all times to respond to rightly ordered approach. It is impossible to overcome ones inhibitions by conscious effort; their existence justifies them. God is on their side, as on that of the victim in Brownings Instans Tyrannus.

DNA from feces and museum specimens confirms a first state record bird by Alec R. Lindsay Ph. D. and Skye C. Haas"DNA from feces and museum specimens confirms a first state record bird" by Alec R. Lindsay Ph. D. and Skye C. Haas
In October 2005, a vagrant kingbird (Aves: Tyrannus sp.) appeared in Michigans Upper Peninsula, nearly 2000 km from the northern limit of its usual range. Using mitochondrial DNA obtained from a fecal sample deposited by the bird and mitochondrial DNA isolated from museum reference specimens, the species iden- tity of this bird was definitively confirmed as a Tropical Kingbird (T. melancholicus) rather than a Couchs Kingbird (T. couchii). This is the first time DNA evidence has been used to establish a state bird record, and one of the few studies of any type to successfully use avian feces for DNA analysis. Circumstantial evidence indicates that this bird was possibly displaced from its original range by Hurricane Wilma in October, 2005. Identification of vagrant birds is important for studying avian populations, and non-invasive genetic sampling techniques should be considered when traditional means of identification fail to provide definitive evidence of identity.

Pacifastin - WikipediaPacifastin - Wikipedia
Pacifastin is a family of serine proteinase inhibitors found in arthropods. Pacifastin inhibits the serine peptidases trypsin and chymotrypsin. All pacifastin members that have been characterized at the molecular level are precursor peptides composed of an N-terminal signal sequence followed by a precursor domain and a variable number of inhibitor domains. Each of these inhibitor domains carries a six-cysteine motif - see below. The first family members to be identified were isolated from Locusta migratoria migratoria(migratory locust) which were HI, LMCI-1 (PMP-D2) and LMCI-2 (PMP-C). A further five members, SGPI-1 to 5, were then isolated from Schistocerca gregaria (desert locust), and a heterodimeric serine protease inhibitor was isolated from the haemolymph of Pacifastacus leniusculus (Signal crayfish), and named pacifastin. Peptide proteinase inhibitors are in many cases synthesised as part of a larger precursor protein, referred to as a propeptide or zymogen, which remains inactive until ...

The phylogenetic position of the four East Asian freshwater crayfish species of the genus Cambaroides is not settled. Morphological phylogenetic analyses suggest close affinities of Cambaroides with North American Cambaridae. This view is based mainly on characters of the male and female reproductive organs. In contrast, the only molecular phylogenetic analysis so far available leaves the phylogenetic position of Cambaroides unresolved. The question of whether Cambaroides is monophyletic or paraphyletic has so far been neither addressed morphologically nor with molecular data sets. Here we present the first comprehensive phylogenetic analysis of all four currently described species of Cambaroides in the framework of Northern Hemisphere freshwater crayfish (Astacoidea) relationships based on partial sequences of two mitochondrial genes (CO1 and 12S rRNA). Despite some evidence in favour of a monophyletic Cambaroides more data is needed to resolve this question. Our ...

Pathogens4
  • 1997), even though efforts have been made to breed for resistance to a wide variety of major pathogens of alfalfa such as Verticillium , Phytophthora , and Aphanomyces . (uwex.edu)
  • Roots and hypocotyls develop light to dark brown lesions, but unlike other root-rot pathogens which cause seedling collapse, hypocotyls infected with Aphanomyces tend to remain rigid, resulting in stunted but upright seedlings (Grau 1990). (uwex.edu)
  • Aphanomyces is an economically important genus of Oomycete pathogens that affect a wide range of hosts including crops such as alfalfa, bean, lentil, pea and sugarbeet. (usda.gov)
  • This proceeding summarizes scientific contributions from a recently held workshop on the genus Aphanomyces that emphasized the importance of these pathogens on legumes and sugarbeet. (usda.gov)
Root rot7
Isolates3
Soil2
  • Aphanomyces survives as oospores (sexual spores) in the soil or in infected plant tissues. (uwex.edu)
  • Soils infested with Aphanomyces inoculum can be detected by planting bait plants into pots containing the field soil of interest and maintaining flooded conditions for 5 days. (uwex.edu)
Control1
  • Apron) are not active against Aphanomyces and therefore, avoiding poorly drained soils and using resistant varieties are the main methods useful for control. (uwex.edu)

Phytophthora1
  • I think this point was made in the entry for _Phytophthora_, so I'm a little surprised by the repeated references to _Aphanomyces_ as a fungus. (blogspot.com)
Euteiches root rot1
Oomycete Aphanomyces euteiches1
Infection2
Root8
  • The disease that manifests in plants infected with these water moulds is sometimes known simply as Aphanomyces root rot or common root rot. (wikipedia.org)
  • Our work provides the first evidence for the potential of OGs in the defense induction in pea against Aphanomyces root rot. (mdpi.com)
  • Effect of seed dressing fungicide and inoculum density on Aphanomyces root rot of field pea in Alberta. (gc.ca)
  • Recently, root rot caused by Aphanomyces euteiches was reported to be a concern where above-normal spring rainfall occurred. (gc.ca)
  • Experiments were conducted to determine effects of seed treatment and inoculum density on Aphanomyces root rot of field pea under greenhouse and field conditions. (gc.ca)
  • However the sterile growth-chamber experiments could be used to study the effect of S. meliloti inoculation on the development of Aphanomyces root rot. (wsu.edu)
  • The soil bacterium Bacillus mycoides MW 27 has excellent potential for development as a biological control agent of Aphanomyces root rot of pea. (lincoln.ac.nz)
  • In this study, we performed a meta-analysis of Aphanomyces root rot resistance QTL in the four main sources of resistance in pea and compared their genomic localization with genes/QTL controlling morphological or phenological traits and with putative candidate genes. (beds.ac.uk)
Diseases3
  • Aphanomyces causes two notifyable diseases: crayfish plague (J. Invertebr. (uis.no)
  • Highly resistant to all major alfalfa diseases, it's resistant to aphanomyces race 2 and has early season resistance to wet soil diseases. (beefmagazine.com)
  • It was the first fish diseases laboratory in Europe accredited for quality standards ISO 9001 and 17025 (EN 45001). (wur.nl)
Resistant3
  • Interestingly, tilapia are resistant to Aphanomyces infections. (vims.edu)
  • Apron) are not active against Aphanomyces and therefore, avoiding poorly drained soils and using resistant varieties are the main methods useful for control. (uwex.edu)
  • A pea-Aphanomyces collection of 175 pea lines, enriched in germplasm derived from previously studied resistant sources, was evaluated for resistance to A. euteiches in field infested nurseries in nine environments and with two strains in climatic chambers. (beds.ac.uk)
Resistance2
Pathogenic1
  • Antibodies cross-reacted with non-pathogenic Aphanomyces spp. (bl.uk)
Inoculum1
  • Soils infested with Aphanomyces inoculum can be detected by planting bait plants into pots containing the field soil of interest and maintaining flooded conditions for 5 days. (uwex.edu)
Drechs1
Skin lesions1
  • Isolation of Aphanomyces sp(p). associated with skin lesions and morta" by AA Shaheen, E Elsayed et al. (wm.edu)
Vitro2
Bacterium1
  • A formulation of the bacterium could be marketed on both its ability to increase yields under Aphanomyces disease pressure, and to limit oospore development, thereby limiting disease in continuous cropping situations. (lincoln.ac.nz)
Roots1
Water2
  • Aphanomyces water moulds are "one of the most important yield-limiting factors in production of legumes and sugarbeet. (wikipedia.org)
  • 2001). A fatal oomycotic disease of the fresh water fish Aplocheilus panchax in India caused by Aphanomyces laevis. (wikipedia.org)
Peas1
  • Taking a break from peas or lentils for six years is a tall order for fields where aphanomyces has been a problem. (realagriculture.com)
