title: Landscape epidemiology of bean pod mottle comovirus: molecular evidence of heterogeneous sources.
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.
