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. In this study, the complete nucleotide sequences of two BrYV isolates from radish and Chinese cabbage were determined. Sequence analysis suggested that these isolates represent a new genotype, referred to here as BrYV-C. The full-length sequences of the two BrYV-C isolates shared 93.4-94.8 % identity with BrYV-A and BrYV-B. Further phylogenetic analysis showed that the BrYV-C isolates formed a subgroup that was distinct from the BrYV-A and BrYV-B isolates based on all of the proteins except P5.
对于被提议为新的杆状病毒属成员的芸薹黄花叶病毒（BrYV），已经描述了两种明显不同的基因型（BrYV-A 和 BrYV-B）。在这项研究中，确定了来自萝卜和白菜的两种 BrYV 分离物的完整核苷酸序列。序列分析表明，这些分离物代表了一种新的基因型，这里称为 BrYV-C。这两个 BrYV-C 分离物的全长序列与 BrYV-A 和 BrYV-B 分别具有 93.4-94.8%的同一性。进一步的系统发育分析表明，BrYV-C 分离物基于除 P5 以外的所有蛋白形成了一个与 BrYV-A 和 BrYV-B 分离物不同的亚群。
