New device and method for capture, reverse transcription and nested PCR in a single closed-tube. (1/117)

A device and improved method based on the use of a compartmentalized Eppendorf tube that allows capture, reverse transcription and nested-PCR in a single closed-tube has been developed and patented. The main advantages of the system are the high sensitivity obtained, the simplicity, the low risk of contamination and the easy establishment of adequate conditions for nested-PCR. The method has been successfully applied to the detection and characterization of citrus tristeza closterovirus and plum pox potyvirus isolates in plant tissues and single aphids squashed on paper. This device and methodology could be easily adapted to the detection of other targets.  (+info)

The haplotype distribution of two genes of citrus tristeza virus is altered after host change or aphid transmission. (2/117)

Genetic variability of citrus tristeza virus (CTV) was studied using the haplotypes detected by single-strand conformation polymorphism (SSCP) analysis of genes p18 and p20 in six virus populations of two origins. The Spanish group included a CTV isolate and subisolates obtained by graft-transmission to different host species. The other included two subisolates aphid-transmitted from a single Japanese isolate. The homozygosity observed for gene p20 was always significantly higher than that expected under neutral evolution, whereas only three populations showed high homozygosity for p18, suggesting stronger host constraints for p20 than for p18. Sequential transmissions of a Spanish isolate to new host species increased the difference between its population and that of the successive subisolates for gene p18, as estimated by the F statistic. Analysis of molecular variance indicated that variation between both groups of populations was not statistically significant, whereas variations between populations of the same group or within populations were significant for both genes studied. Our data indicate that selection affects the haplotype distribution and that adaptation to a new host can be as important or more as the geographical origin. Variation of the CTV populations after host change or aphid transmission may explain in part the wide biological variability observed among CTV isolates.  (+info)

The complete genome sequence of the major component of a mild citrus tristeza virus isolate. (3/117)

The genome of the Spanish mild isolate T385 of citrus tristeza virus (CTV) was completely sequenced and compared with the genomes of the severe isolates T36 (Florida), VT (Israel) and SY568 (California). The genome of T385 was 19,259 nt in length, 37 nt shorter than the genome of T36, and 33 and 10 nt longer than those of VT and SY568, respectively, but their organization was identical. T385 had mean nucleotide identities of 81.3, 89.3 and 94% with T36, VT and SY568, respectively. The 3' UTR had over 97% identity in all isolates, whereas the 5' UTR of T385 had 67% identity with VT, 66.3% with SY568 and only 42.5% with T36. In the coding regions, the nucleotide differences between T385 and VT were evenly distributed along the genome (around 90% identity); this was not observed between T385 and the other isolates. T385 and T36 had nucleotide identities around 90% in the eight 3'-terminal ORFs of the genome, but only 72.3% in ORF 1a, a divergence pattern similar to that reported previously for T36 and VT. T385 and SY568 had nucleotide identities close to 90% in the 5'- and 3'-terminal regions of the genome, whereas the central region had over 99% identity. Our data suggest that the central region in the SY568 genome results from RNA recombination between two CTV genomes, one of which was almost identical to T385.  (+info)

New defective RNAs from citrus tristeza virus: evidence for a replicase-driven template switching mechanism in their generation. (4/117)

Defective RNAs (D-RNAs) ranging in size from 1968 to 2759 nt were detected in four citrus tristeza virus (CTV) isolates by hybridization of electroblotted dsRNAs with two probes specific for the 5'- and 3'-terminal genomic regions. The RNAs that hybridized with both probes were eluted, cloned and sequenced. Comparison with the sequences of the corresponding genomic regions of the helper virus showed, in all cases, over 99% nucleotide identity and direct repeats of 4-5 nt flanking or in the vicinity of the junction sites. The presence of the repeats from two separate genome locations suggests a replicase-driven template switching mechanism for the generation of these CTV D-RNAs. Two of the CTV isolates that differed greatly in their pathogenicity contained an identical D-RNA, suggesting that it is unlikely that this D-RNA is involved in symptom modulation, which may be caused by another factor.  (+info)

Lettuce infectious yellows virus: in vitro acquisition analysis using partially purified virions and the whitefly Bemisia tabaci. (5/117)

Virions of lettuce infectious yellows virus (LIYV; genus Crinivirus) were purified from LIYV-infected plants and their protein composition was analysed by SDS-PAGE and immunoblotting. Virion preparations contained the major capsid protein (CP), but the minor capsid protein (CPm), p59 and the HSP70 homologue were also identified by immunoblot analysis. Immunogold labelling analysis showed that CP constituted the majority of the LIYV virion capsid, but CPm was also part of the capsid and localized to one end of the virion, similar to the polar morphology seen for viruses in the genus Closterovirus. p59 and the HSP70 homologue were not detected on virions by immunogold labelling, but were always detected in virion preparations by immunoblot analysis. Purified LIYV virions were used for in vitro acquisition analysis with Bemisia tabaci whiteflies and were efficiently transmitted to plants. Infectivity neutralization analyses were done using antisera to the LIYV-encoded CP, CPm, p59 and HSP70 homologue. Only antiserum to the CPm effectively neutralized LIYV transmission by B. tabaci. These data suggest that the LIYV-B. tabaci transmission determinants are associated with purified virions, and that the LIYV virion structural protein CPm is involved in transmission by B. tobaci.  (+info)

An engineered closterovirus RNA replicon and analysis of heterologous terminal sequences for replication. (6/117)

Citrus tristeza virus (CTV) populations in citrus trees are unusually complex mixtures of viral genotypes and defective RNAs developed during the long-term vegetative propagation of the virus and by additional mixing by aphid transmission. The viral replication process allows the maintenance of minor amounts of disparate genotypes and defective RNAs in these populations. CTV is a member of the Closteroviridae possessing a positive-stranded RNA genome of approximately 20 kilobases that expresses the replicase-associated genes as an approximately 400-kDa polyprotein and the remaining 10 3' genes through subgenomic mRNAs. A full-length cDNA clone of CTV was generated from which RNA transcripts capable of replication in protoplasts were derived. The large size of cDNA hampered its use as a genetic system. Deletion of 10 3' genes resulted in an efficient RNA replicon that was easy to manipulate. To investigate the origin and maintenance of the genotypes in CTV populations, we tested the CTV replicase for its acceptance of divergent sequences by creating chimeric replicons with heterologous termini and examining their ability to replicate. Exchange of the similar 3' termini resulted in efficient replication whereas substitution of the divergent (up to 58% difference in sequence) 5' termini resulted in reduced but significant replication, generally in proportion to the extent of sequence divergence.  (+info)

Subcellular localization of the HSP70-homolog encoded by beet yellows closterovirus. (7/117)

Closteroviridae is the only viral family coding for a homolog of HSP70 (HSP70h). Polyclonal antiserum to recombinant beet yellows closterovirus (BYV) HSP70h was generated and used for immunogold labeling of the leaf samples derived from the infected Nicotiana benthamiana plants. Ultrastructural analysis revealed the preferential accumulation of BYV in phloem, although occasional infection of the leaf mesophyll cells was also observed. The strongest HSP70h-specific labeling was associated with virion aggregates and vesicles harboring scattered virions. HSP70h was also observed in close proximity of plasmodesmata and inside the plasmodesmatal channels. The possible role of the BYV HSP70h in RNA encapsidation was tested in tobacco protoplasts. A BYV mutant possessing an inactivated HSP70h gene exhibited no detectable encapsidation defects. Collectively, the obtained results suggested that closteroviral HSP70h escorts the virions to their destinations inside the infected cells and possibly participates in the intercellular translocation of BYV.  (+info)

Regulation of closterovirus gene expression examined by insertion of a self-processing reporter and by northern hybridization. (8/117)

A reporter open reading frame (ORF) coding for a fusion of bacterial beta-glucuronidase (GUS) with a proteinase domain (Pro) derived from tobacco etch potyvirus was utilized for tagging individual genes of beet yellows closterovirus (BYV). Insertion of this reporter ORF between the first and second codons of the BYV ORFs encoding the HSP70 homolog (HSP70h), a major capsid protein (CP), and a 20-kDa protein (p20) resulted in the expression of the processed GUS-Pro reporter from corresponding subgenomic RNAs. The high sensitivity of GUS assays permitted temporal analysis of reporter accumulation, revealing early expression from the HSP70h promoter, followed by the CP promoter and later the p20 promoter. The kinetics of transcription of the remaining BYV genes encoding a 64-kDa protein (p64), a minor capsid protein (CPm), and a 21-kDa protein (p21) were examined via Northern blot analysis. Taken together, the data indicated that the temporal regulation of BYV gene expression includes early (HSP70h, CPm, CP, and p21 promoters) and late (p64 and p20 promoters) phases. It was also demonstrated that the deletion of six viral genes that are nonessential for RNA amplification resulted in a dramatic increase in the level of transcription from one of the two remaining subgenomic promoters. Comparison with other positive-strand RNA viruses producing multiple subgenomic RNAs showed the uniqueness of the pattern of closterovirus transcriptional regulation.  (+info)

Citrus tristeza virus (CTV), a member of the Closteroviridae, has a 19.3-kb positive-stranded RNA genome that is organized into 12 open reading frames (ORFs) with the 10 3 genes expressed via a nested set of nine or ten 3-coterminal subgenomic mRNAs (sgRNAs). Relatively large amounts of negative-stranded RNAs complementary to both genomic and sgRNAs accumulate in infected cells. As is characteristic of RNA viruses, wild-type CTV produced more positive than negative strands, with the plus-to-minus ratios of genomic and sgRNAs estimated at 10 to 20:1 and 40 to 50:1, respectively. However, a mutant with all of the 3 genes deleted replicated efficiently, but produced plus to minus strands at a markedly decreased ratio of 1 to 2:1. Deletion analysis of 3-end genes revealed that the p23 ORF was involved in asymmetric RNA accumulation. A mutation which caused a frameshift after the fifth codon resulted in nearly symmetrical RNA accumulation, suggesting that the p23 protein, not a cis-acting element within

Survival analysis of the spatio-temporal spread of citrus tristeza virus. 9th Biennial Meeting of the Florida Phytopathological Society, 2-4 May, 2005, University of Florida/IFAS, Mid-Florida Research and Education Center, Apopka, FL. Interpretive Summary: Citrus Tristeza Virus (CTV) remains one of the most severe pathogens of citrus worldwide, causing large production losses and has caused the death of over 50 million trees. Understanding the disease dynamics is key to developing control measures. One aspect that is poorly understood is the interaction of various strains of CTV under field conditions. An analytical method called survival analysis, originating from the medical and engineering disciplines, was used for the first time to investigate the interaction of two field strains of the CTV virus and how they interact. The method was modified to be able to examine the effect of diseased trees within a near vicinity on the probability of a tree remaining disease ...

Five isolates of a new putative member of the genus Closterovirus, tentatively named blackcurrant leafroll associated virus 1 (BcLRaV-1), were identified in currant. The 17 kb long genome of BcLRaV-1 contained 10 open reading frames (ORFs). The replication associated polyprotein has two papain-like leader proteases, a methyltransferase, a helicase and an RNA-dependent RNA polymerase domain. Additional ORFs coded for heat shock protein 70 homolog, heat shock protein 90 homolog, two divergent copies of coat protein, and three accessory proteins without identifiable functions. Phylogenetic analysis showed that BcLRaV-1 is related to members of the genus Closterovirus and recombination analysis of the isolates showed clear evidences of intraspecies recombination.
Citrus Diseases Exotic to Florida: Citrus Tristeza Virus Stem Pitting (CTV-SP) 3 Vein chlorosis caused by Citrus tristeza virus-Stem Pitting (CTV-SP). As with decline isolates, CTV-SP isolates can be transmitted by budding and grafting. Long distance movement of CTV-SP to different countries or different areas within a region is usually via the movement of the infected budwood or nursery stock. CTV-SP is also transmitted by several species of aphids. The brown citrus aphid (Toxoptera citricida) is considered the most efficient vector, but the melon aphid (Aphis gossypii) and the spirea aphid (A. spiraecola) can also transmit the CTV-SP virus. The patterns of spread vary according to the type of aphids involved. CTV-SP problem often increases rapidly after the brown citrus aphid becomes established in a new area and it seems that CTV-SP isolates are transmitted more often by brown citrus aphid as compared to other aphids. CTV can be transmitted experimentally by stem slash inoculation of citrus ...
New cultivars are obtained from the discovery of mutations in orchards, the breeding programme at the Institute for Tropical and Subtropical Crops (ITSC) (previously known as the CSFRI) and the importation of promising cultivars from other countries. Since the deregulation of the citrus industry in 1997 private cultivar agents have also become involved in this process and the Citrus Growers Association now has their own Cultivar Company for cultivar development. The ITSC and the CRI facility in Nelspruit are responsible for shoot-tip grafting and pre-immunisation of material with a mild strain of Citrus Tristeza Virus. The Citrus Foundation Block is responsible for increase and release of propagation material to the citrus industry. All promising cultivars are planted in suitable trial sites and evaluated by CRI Cultivar Specialists. The CIS Advisory Committee is responsible for the co-ordination of these processes.. ...

Hybridization analysis showed a p27 gene region, which exhibits different patterns with two probes derived from two biological distinct CTV isolates. In an attempt to screen whether that gene region differs in mild and severe strains, six CTV isolates belonging to different biogroups were compared for variations in their p27 gene by analysis of single-strand conformation polymorphism (SSCP). The p27 gene was reverse transcribed and amplified by PCR and thirty clones of each isolate were obtained. From each clone, two fragments of the gene were amplified by PCR: fragment (a), 459 bp long, and fragment (b), 281 bp long. Sequence variations in both gene fragments were studied by SSCP analysis. A variety of SSCP patterns was obtained from each isolate, being isolates belonging to the groups II-IV and III those with the higher and lower number of them. Moreover, SSCP analysis provided a rapid procedure to screen the genetic heterogeneity of the viral isolate reducing considerably the amount of ...

THE precepts of the eleventh class are enumerated in the Section on Divine Service (Sefer abodah) and the Section on Sacrifices (Sefer ha-korbanot). We have described their use in general terms (chap. xxxii.). I will now proceed to give the reason of each precept separately. Scripture tells us, according to the Version of Onkelos, that the Egyptians worshipped Aries, and therefore abstained from killing sheep, and held shepherds in contempt. Comp. Behold we shall sacrifice the abomination of the Egyptians, etc. (Exod. viii. 26); For every shepherd is an abomination to the Egyptians (Gen. xlvi. 34). Some sects among the Sabeans worshipped demons, and imagined that these assumed the form of goats, and called them therefore goats This worship was widespread. Comp. And they shall no more offer their sacrifices unto demons, after whom they have gone a whoring (Lev. xvii. 7). For this reason those sects abstained from eating goats flesh. Most idolaters objected to killing cattle, holding ...

Grapevine leafroll disease is widely accepted to be the most damaging grapevine virus disease in South Africa, with grapevine leafroll-associated virus 3 (GLRaV-3) the most prevalent leafroll-associated virus (Pietersen, 2006). The vine mealybug, Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae), is the most common and efficient vector of GLRaV-3 in South Africa (Walton & Pringle, 2004; Douglas & Krüger, 2008). Currently, the industry strategy to limit leafroll infection in newly planted, leafroll-free vineyards in South Africa is based on a multi-pronged approach that includes treating young grapevines with a systemic insecticide like imidacloprid shortly after planting; monitoring for leafroll symptoms in these vineyards over two seasons, and removing all leafroll-infected grapevines, known as rogueing (Pietersen, 2006); monitoring and controlling mealybug in adjacent leafroll-infected vineyards where rogueing is not feasible; and ensuring that workers and equipment do ...
Citrus plants are very liable to infestation by aphids, whitefly and scale insects (e.g. California red scale). Also rather important are the viral infections to which some of these ectoparasites serve as vectors such as the aphid-transmitted Citrus tristeza virus which when unchecked by proper methods of control is devastating to citrine plantations. The newest threat to citrus groves in the United States is the Asian citrus psyllid.. The Asian citrus psyllid is an aphid-like insect that feeds on the leaves and stems of citrus trees and other citrus-like plants - but the real danger lies in that it can carry a deadly, bacterial tree disease called Huanglongbing (HLB), also known as citrus greening disease.[25]. In August 2005 citrus greening disease was discovered in the south Florida region around Homestead and Florida City. It has since spread to every commercial citrus grove in Florida. In 2004-2005 USDA Ag statistics reported the total Florida citrus production to be 169.1 million boxes of ...
El sureste español se encuentra localizado en un área que destaca por su importante sector agrícola, reconocido por su alta producción de cultivos como el pimiento y el melón, los cuales se ven afectados por enfermedades causadas por patógenos del suelo, como la tristeza y la fusariosis vascular respectivamente. Una detección temprana de los agentes causantes de estas enfermedades es de gran importancia, para evitar su expansión a nuevos terrenos y mejorar su control mediante una gestión integrada. Por esta razón, desarrollamos un sistema TaqMan para detectar y cuantificar Phytophthora nicotianae específicamente mediante PCR a tiempo real (qPCR) en cultivo puro y en matrices ambientales como suelo, compost y tejido vegetal. Con este sistema se identificó P. nicotianae como el actual causante de la tristeza del pimiento en el Campo de Cartagena y su población fue caracterizada mediante el uso de marcadores moleculares y un estudio fenotípico. Además, la aplicación del sistema ...
Hibiscus latent Singapore virus (HLSV) is a member of Tobamovirus and its full-length cDNA clones were constructed. The in vitro transcripts from two HLSV full-length cDNA clones, which contain a hepta-adenosine stretch (pHLSV-7A) and an octo-adenosine stretch (pHLSV-8A), are both infectious. The replication level of HLSV-7A in Nicotiana benthamiana protoplasts was 5-fold lower, as compared to that of HLSV-8A. The replicase proteins of HLSV-7A were produced through programmed -1 ribosomal frameshift (-1 PRF) and the 7A stretch was a slippery sequence for -1 PRF. Mutations to the downstream pseudoknot of 7A stretch showed that the pseudoknot was not required for the frameshift in vitro. The stretch was found to be extended to 8A after subsequent replication cycles in vivo. It is envisaged that HLSV employs the monotonous runs of A and -1 PRF to convert its 7A to 8A to reach higher replication for its survival in plants. © 2013 Elsevier Inc ...
This publication is part of a series about understanding nutrient requirements for citrus trees. For the rest of the series, visit http://edis.ifas.ufl.edu/topic_series_citrus_tree_nutrients.. To maintain a viable citrus industry, Florida growers must consistently and economically produce large, high-quality fruit crops from year to year. Efficiently producing maximum yields of high-quality fruit is difficult without understanding soil and nutrient requirements of bearing citrus trees. Most Florida citrus is grown on soils inherently low in fertility with low cation exchange capacity (CEC) and low water-holding capacity, thus soils are unable to retain sufficient quantities of available plant nutrients against leaching caused by rainfall or excessive irrigation.. Seventeen elements are considered necessary for the growth of green plants: carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), sulfur (S), manganese (Mn), zinc (Zn), iron ...
Oil sprays on the trunks of citrus trees prevent infestation by aphids, mites and mealybugs. These pests will eat a trees young leaves and buds, preventing it from fruiting. Oil sprays can also be used on infested areas of citrus trees to remove the insects without harming any of the delicate growth.
Cold weather is on its way, and many people are concerned about their citrus trees. One of the most common questions I get from gardeners is, How much cold can citrus trees tolerate? Because there are a number of variables, its difficult to pin point a threshold temperature at which it becomes necessary to protect your trees.
As citrus have a low tolerance to heat, autumn and winter are ideal for focusing on the care of these trees. Treatments performed now will help keep citrus trees healthy year-round.
Citrus trees start to bloom early in the winter months and they continue to develop throughout the springtime producing minute, green fruits. The fruit grow larger as the seasons progress into summer and fall. The term citrus is a familiar term and type of blossoming plants that belong to the Rutaceae plant ...

The International Committee on the Taxonomy of Viruses (ITCV) has divided the BYDVs into two viruses, BYDV (PAV and MAV) and cereal yellow dwarf polero-virus, CYDV (RPV) (DArcy et al., 1999), according to the previous grouping based on cytopathology (Gill and Chong, 1979), serology and nucleic acid sequences (Martin and DArcy, 1990).. Barley yellow dwarf luteoviruses are restricted to the Poaceae (Gramineae). Cultivated hosts include all the major cereal crops: barley, maize, oat, rice, rye and wheat, as well as many annual and perennial cultivated and wild grasses. BYD has been reported from over 50 countries (Lister and Ranieri, 1995). Symptoms caused by BYDVs differ with the host species and cultivar, the age and the physiological condition of the host plant at the time of infection, the strain and the environmental conditions; and they can be easily confused with nutritional and abiotic disorders. In wheat, one symptom includes leaf discoloration from tip to base and from margin to centre, ...

  • To facilitate studies of the function of HSP70 homolog (HSP70h) in viral infection, the beet yellows closterovirus (BYV) was modified to express green fluorescent protein. (pnas.org)
  • Putative 65 kDa protein of beet yellows closterovirus is a homologue of HSP70 heat shock proteins. (expasy.org)
  • HSP70-related 65 kDa protein of beet yellows closterovirus is a microtubule-binding protein. (termsreign.ga)
  • In vitro transcripts from cloned cDNAs of the lettuce infectious yellows closterovirus bipartite genomic RNAs are competent for replication in Nico. (nih.gov)
  • In vitro transcripts from cloned cDNAs of the lettuce infectious yellows closterovirus bipartite genomic RNAs are competent for replication in Nicotiana benthamiana protoplasts. (nih.gov)
  • Viruses in Closterovirus are non-enveloped, with flexuous and Filamentous geometries. (wikipedia.org)
  • Thus, organization of the BYSV genome is intermediate between that of BYV and CTV, suggesting that these three viruses might represent three distinct stages in closterovirus evolution. (ictvonline.org)
  • These data also indicated that the C-terminally truncated PVX CP lacked a movement function which could be provided in trans by the CPs of other filamentous viruses, whereas another movement determinant specified by some region outside the most C-terminal part of the PVX CP could not be complemented either by potyvirus or closterovirus CPs. (microbiologyresearch.org)
  • CTV is a member of the closterovirus group of plant viruses with long flexuous rod-shaped particles. (ufl.edu)
  • Full-length cloned cDNAs of lettuce infectious yellows closterovirus (LIYV) RNAs 1 and 2 were constructed and fused to the bacteriophage T3 RNA polymerase promoter. (nih.gov)
  • These data demonstrate that LIYV genomic RNAs are competent for replication in mesophyll protoplasts and that infectious in vitro transcripts can be derived from the cloned cDNAs of a closterovirus genome. (nih.gov)
  • The development of this protoplast system is significant for studies of closterovirus replication. (apsnet.org)
  • Closterovirus coat protein (IPR002679) This family consist of coat proteins from closterovirus, which belong to the Closteroviridae, which have a positive strand ssRNA genome with no DNA stage during replication. (ebi.ac.uk)

  • En este trabajo se estimó la estructura poblacional y variación genética del virus del amarillamiento de las venas de la papa (PYVV) infectando cultivos en Colombia por medio del análisis de 69 secuencias nucleotídicas y aminoácidos deducidos de la proteína mayor de la cápside (CP) reportados en el banco de genes (GenBank). (scielo.org.co)
  • This closterovirus penetrates the host cell and proceeds to release the viral genomic RNA into the cell's cytoplasm. (tsusinvasives.org)
  • Closterovirus infection and mealybug exposure are necessary for the development of mealybug wilt of pineapple disease. (thefreedictionary.com)
  • Furthermore, we suggest that sequencing one million reads will provide sufficient genome coverage specifically for closterovirus detection. (biomedcentral.com)
  • These data demonstrated that the potyvirus CPs and both the major and minor CPs of beet yellows closterovirus could complement cell-to-cell movement of PVX.CP-Xho but not PVX.ΔCP. (microbiologyresearch.org)
  • In Iran, a survey was carried out in central Mazandaran (near the Caspian Sea) in 1996, to determine the possible spread of citrus tristeza closterovirus (EPPO A2 quarantine pest) from the initial infested foci (Mahdasht orchards in Sari). (eppo.int)
