Abstract

The Potyviridae family has been divided into four genera on the basis of vector transmission, as follows: Potyvirus genus (aphid), Rymovirus genus (mite), Bymovirus genus (fungus) and Ipomovirus genus (whitefly). However recent sequence comparisons of the coat protein and 3' NCR regions of the potyviruses have demonstrated that the rymoviruses appear to be a group of two unrelated clusters namely Ryegrass Mosaic Virus (RGMV), Agropyron Mosaic Virus (AgMV) and Hordeum Mosaic Virus (HoMV) in one group and Wheat Streak Mosaic Virus (WSMV) and Brome Streak Mosaic Virus (BrSMV) in the second group. We therefore propose that RGMV, AgMV and HoMV remain in the genus Rymovirus and WSMV and BrSMV form a separate genus, possibly the Whestrevirus genus.

摘要

根据传毒介体，马铃薯Y病毒科已被分为四个属，如下：马铃薯Y病毒属（蚜虫传播）、黑麦草花叶病毒属（叶螨传播）、大麦花叶病毒属（真菌传播）和甘薯褪绿斑驳病毒属（粉虱传播）。然而，最近对马铃薯Y病毒属病毒外壳蛋白和3'非编码区的序列比较表明，黑麦草花叶病毒属病毒似乎是两个不相关的簇群，即第一组中的黑麦草花叶病毒（RGMV）、冰草花叶病毒（AgMV）和大麦花叶病毒（HoMV），以及第二组中的小麦线条花叶病毒（WSMV）和雀麦线条花叶病毒（BrSMV）。因此，我们建议将RGMV、AgMV和HoMV保留在黑麦草花叶病毒属中，而WSMV和BrSMV组成一个单独的属，可能是小麦线条病毒属。
