| the genome sequence of pepper vein yellows virus (family luteoviridae, genus polerovirus). | the complete genome of pepper vein yellows virus (pevyv) was sequenced using random amplification of rna samples isolated from vector insects (aphis gossypii) that had been given access to pevyv-infected plants. the pevyv genome consisted of 6244 nucleotides and had a genomic organization characteristic of members of the genus polerovirus. pevyv had highest amino acid sequence identities in orf0 to orf3 (75.9 - 91.9%) with tobacco vein distorting polerovirus, with which it was only 25.1% identic ... | 2011 | 21400195 |
| high prevalence of poleroviruses in field-grown pepper in turkey and tunisia. | open-field pepper crops were sampled in 2011 in turkey and tunisia and surveyed for the major pepper-infecting viruses. as expected, potato virus y and cucumber mosaic virus (in both countries), and tobacco etch virus (in turkey only) were quite frequent. however, poleroviruses were the most common viruses, with prevalences above 70 %. partial sequence analyses revealed the occurrence of poleroviruses resembling either beet western yellows virus (bwyv) or pepper vein yellows virus in the sampled ... | 2013 | 23183831 |
| first complete genome sequence of pepper vein yellows virus from australia. | we present here the first complete genomic rna sequence of the polerovirus pepper vein yellows virus (pevyv) obtained from a pepper plant in australia. we compare it with complete pevyv genomes from japan and china. the australian genome was more closely related to the japanese than the chinese genome. | 2016 | 27231375 |
| insights into the etiology of polerovirus-induced pepper yellows disease. | the study of an emerging yellows disease of pepper crops (pepper yellows disease [pyd]) in greece led to the identification of a polerovirus closely related to pepper vein yellows virus (pevyv). recovery of its full genome sequence by next-generation sequencing of small interfering rnas allowed its characterization as a new poleroviruses, which was provisionally named pepper yellows virus (peyv). transmission experiments revealed its association with the disease. sequence similarity and phylogen ... | 2017 | 28786341 |
| evidence for a complex of emergent poleroviruses affecting pepper worldwide. | in recent years, symptoms of vein yellowing and leaf roll in pepper crops associated with the presence of poleroviruses (genus polerovirus, family luteoviridae) have been emerging in many countries worldwide. spain was the first country in europe where the yellowing disease of pepper was observed. in this work, a polerovirus isolate from spain that infects pepper and has been shown to be transmitted by the aphid aphis gossyppii (spain-almería 2-2013) was sequenced and compared with isolates from ... | 2018 | 29372406 |
| complete genome sequence of a chinese isolate of pepper vein yellows virus and evolutionary analysis based on the cp, mp and rdrp coding regions. | the genome sequence of pepper vein yellows virus (pevyv) (pevyv-hn, accession number kp326573), isolated from pepper plants (capsicum annuum l.) grown at the hunan vegetables institute (changsha, hunan, china), was determined by deep sequencing of small rnas. the pevyv-hn genome consists of 6244 nucleotides, contains six open reading frames (orfs), and is similar to that of an isolate (ab594828) from japan. its genomic organization is similar to that of members of the genus polerovirus. sequence ... | 2016 | 26620586 |
| analysis of sequences from field samples reveals the presence of the recently described pepper vein yellows virus (genus polerovirus) in six additional countries. | polerovirus infection was detected by reverse transcription polymerase chain reaction (rt-pcr) in 29 pepper plants (capsicum spp.) and one black nightshade plant (solanum nigrum) sample collected from fields in india, indonesia, mali, philippines, thailand and taiwan. at least two representative samples for each country were selected to generate a general polerovirus rt-pcr product of 1.4 kb length for sequencing. sequence analysis of the partial genome sequences revealed the presence of pepper ... | 2013 | 23307365 |
| virus surveys of capsicum spp. in the republic of benin reveal the prevalence of pepper vein yellows virus and the identification of a previously uncharacterised polerovirus species. | surveys were conducted in 2014 and 2015 in southern and northern benin, respectively, to identify the viruses infecting peppers (capsicum spp.). the samples were screened by elisa for cucumber mosaic virus (cmv), pepper veinal mottle virus (pvmv), potato virus y (pvy) and tomato yellow leaf curl virus (tylcv). a generic reverse transcription pcr (rt-pcr) was used to test for the presence of poleroviruses. elisa tests confirmed the prevalence of all viruses, while the rt-pcr detected pepper vein ... | 2017 | 28220324 |
