Abstract

Soil-borne wheat mosaic virus (SBWMV) in the genus Furovirus is divided into Nebraska-like (NE) group and New York-like (NY) group on genomic sequences. Isolates Hk-Is and Hk-Tk showed more than 97% nucleotide identities to group NE and ca. 90% to group NY both in RNA1 and RNA2, and phylogenetic analyses revealed their affiliation to group NE. Another isolate Kgw, however, was closely and distantly related to the American groups in RNA1 and RNA2, respectively (95% and 88% nucleotide sequence identity to group NE). Consequently, it is concluded that the isolate Kgw is distantly related to the American group.

日本土传小麦花叶病毒属分离物的分子特征

根据基因组序列，呋喃病毒属中的土传小麦花叶病毒（SBWMV）被分为内布拉斯加样（NE）组和纽约样（NY）组。分离物 Hk-Is 和 Hk-Tk 在 RNA1 和 RNA2 中与 NE 组的核苷酸相同度超过 97%，与 NY 组的相同度约为 90%，系统进化分析表明它们属于 NE 组。然而，另一个分离物 Kgw 在 RNA1 和 RNA2 中分别与美洲组亲缘关系密切和疏远（与 NE 组的核苷酸序列同一性分别为 95% 和 88%）。因此，可以断定分离物 Kgw 与美洲组的亲缘关系较远。
