Abstract

Bean pod mottle virus (BPMV) RNAs are grouped into subgroups (sgI and sgII). A BPMV partial diploid reassortant (IA-Di1) from the perennial Desmodium illinoense contained both RNA1 subgroups and an RNA1 recombinant. The RNA2 of IA-Di1 was characteristic of sgII. Additionally, ten BPMV isolates from a soybean field adjacent to the locality of IA-Di1 shared >98.5% nucleotide identity with RNA1 sgII of IA-Di1. The data demonstrate the co-existence of two differing consensus BPMV RNA1 subgroups in adjacent habitats and illustrate variation in virus genetic structure that can occur in a contiguous plant community.

摘要

豇豆花叶病毒（BPMV）RNA 分为亚组（sgI 和 sgII）。一种来自多年生鸡眼草的 BPMV 部分二倍体重组体（IA-Di1）同时包含了 RNA1 亚组和一个 RNA1 重组体。IA-Di1 的 RNA2 具有 sgII 的特征。此外，IA-Di1 所在地附近大豆田的 10 个 BPMV 分离株与 IA-Di1 的 RNA1 sgII 具有 >98.5%的核苷酸同一性。这些数据表明，在相邻生境中同时存在两种不同的 BPMV RNA1 共有亚组，并说明了在连续的植物群落中可能发生的病毒遗传结构变异。
