Brassica yellows virus BrYV prevalently distributed throughout mainland China and South Korea while triggering serious diseases in cruciferous crops is proposed to be a new species in the genus Polerovirus within the family Luteoviridae. The virus was first identified in cruciferous crops in China and prevalently distributed throughout Mainland China and South Korea 6 7 8.

Brassica yellows virus. The NCBI taxonomy database is not an authoritative source for. Brassica yellows virus BrYV a newly identified polerovirus infects crucifer crops in China and causes yellowing or leaf-roll symptoms Xiang et al 2011. BrYV are widely spread in China as well 43 as in South Korea and Japan 41011.

BrYV isdistributed widely in mainland China as well as in South. This study isolated different poleroviruses from sugar beet spinach radish and brassica in Japan and identified them as BWYV-JP Beet leaf yellowing virus BLYV Brassica yellows virus BrYV and BrYV-R radish strain based on host range and molecular analysis. These three viruses occasionally cause significant economic loss but their occurrence is spasmodic.

A list of our current non-bibliographic LinkOut providers can be found here. Three viruses are recorded infecting vegetable brassica crops in Western Australia turnip mosaic virus cauliflower mosaic virus and beet western yellows virus also known as turnip yellows virus. Brassica yellows virus BrYV is a newly identified polerovirus 3 which has a vast range of hosts and is widespread in mainland China South Korea and Japan 3 4.

To date three distinct genotypes of BrYV BrYV-A -B and -C have been identified 3 5 6. Here we verified the pathogenicity of the polerovirus Brassica yellows virus BrYV by transforming its full-length amplicon into Arabidopsis thaliana which resulted in many abnormal phenotypes. Sequence analysis suggested that these isolates represent a new genotype referred to here as BrYV-C.

BrYV has a wide range of hosts which mainly infects the 44 Cabbage Brassica oleracea varcapitata Chinese cabbage Bpekinensis Cauliflower. Brassica yellows virus BrYV is an aphid-transmitted and phloem-limited virus as other poleroviruses do unpublished data. Brassica yellows virus is a newly identified species in the genus of Polerovirus within the family Luteoviridae.

Brassica yellows virus BrYV is prevalently distributed throughout Mainland China and South Korea is an important virus infecting cruciferous crops.

Brassica yellows virus TAX1046403 Lineage. For brassica yellows virus BrYV proposed to be a member of a new polerovirus species two clearly distinct genotypes BrYV-A and BrYV-B have been described. However the molecular mechanism behind these viral-induced symptoms is still unknown.

41 Brassica yellows virus BrYV is a tentative newly identified species in the genus of Polerovirus 42 which is closely related to TuYV Turnip yellows virus 89. Generally BrYV genome is composed of a single-strand positive-sense RNA of 57 kb. Brassica yellows virusBrYV is an aphid-transmitted and phloem-limited virusas other poleroviruses do unpublished data.

In this study the complete nucleotide sequences of two BrYV isolates from radish and Chinese cabbage were determined. Brassica yellows virus is a newly identified species in thegenus of Polerovirus which was closely related to butdistinct fromTunip yellows virusTuYV in terms of P0P3 P4 and P5 gene sequences. Brassica yellows virus is a newly identified species in the genus of Polerovirus which was closely related to but distinct from Tunip yellows virus TuYV in terms of P0 P3 P4 and P5 gene sequences.
