We determined the complete genomic sequence of begonia flower breaking virus (BFBV), a novel putative member of the genus Potyvirus isolated from Begonia bowerae cv. ‘Tiger’ plants grown in Kunming. The genomic RNA comprises 9540 nucleotides (nt), excluding the 3’-terminal poly(A) tail, and contains a typical open reading frame (ORF) of potyviruses. The ORF consists of 9219 nucleotides and encodes a 3073-amino-acid polyprotein that is predicted to be proteolytically cleaved into 10 mature peptides. Sequence comparison indicated that BFBV shares 43.9–55.12% amino acid sequence identity with known potyviruses and that BFBV shares the highest amino acid sequence identity (55.12%) with beet mosaic virus. The results from the complete genomic sequence analysis further suggest that BFBV is a member of a novel species in the genus Potyvirus.

秋海棠断花病毒的完整基因组序列,该病毒是波多病毒属的新成员。

我们确定了秋海棠断花病毒(BFBV)的完整基因组序列,秋海棠花断开病毒是从海棠秋海棠中分离出来的一种新的假定的马铃薯病毒属成员。简历。在昆明种植的“老虎”植物。基因组RNA包含9540个核苷酸(nt),不包括3'末端的poly(A)尾部,并包含典型的马铃薯病毒开放阅读框(ORF)。ORF由9219个核苷酸组成,编码一个3073个氨基酸的多聚蛋白,该蛋白被蛋白水解切割为10个成熟的肽。序列比较表明,BFBV与已知的马铃薯病毒具有43.9–55.12%的氨基酸序列同一性,并且BFBV与甜菜花叶病毒具有最高的氨基酸序列同一性(55.12%)。从完整的基因组序列分析的结果进一步表明,BFBV是在属新颖的物种成员马铃薯Y病毒
