The genomic RNA sequences of two genotypes of a brassica-infecting polerovirus from China were determined. Sequence analysis revealed that the virus was closely related to but significantly different from turnip yellows virus (TuYV). This virus and other poleroviruses, including TuYV, had less than 90% amino acid sequence identity in all gene products except the coat protein. Based on the molecular criterion (>10% amino acid sequence difference) for species demarcation in the genus Polerovirus, the virus represents a distinct species for which the name Brassica yellows virus (BrYV) is proposed. Interestingly, there were two genotypes of BrYV, which mainly differed in the 5'-terminal half of the genome.
从中国的两种甘蓝类作物侵染的马铃薯 Y 病毒属病毒中分离到了基因组 RNA 序列。序列分析表明，该病毒与芜菁黄花叶病毒（TuYV）密切相关，但存在显著差异。该病毒与其他马铃薯 Y 病毒属病毒，包括 TuYV，除外壳蛋白外，所有基因产物的氨基酸序列同一性均低于 90%。根据马铃薯 Y 病毒属物种划分的分子标准（>10%氨基酸序列差异），该病毒代表了一个独特的种，建议命名为甘蓝黄花叶病毒（BrYV）。有趣的是，BrYV 存在两种基因型，主要差异在于基因组 5' 端的一半。
