摘要
Cucumber mosaic virus (CMV) is a type member of the genus Cucumovirus, which has a tripartite RNA virus and has been divided into three subgroups, designated as IA, IB, and II. At the present time, almost all reported CMV strains belong to subgroups IA and IB. In our present work, a CMV strain, designated CMV-Mb, was obtained from a Musa basjoo plant. The complete sequence of CMV-Mb genomic RNAs has been determined and analyzed. The results of sequence comparison and phylogenetic analysis revealed that CMV-Mb is a unique natural subgroup II strain in the Musa plant and can serve as an additional reference strain for the molecular epidemiology of subgroup II Cucumovirus. The present work is the first report of a natural homozygote subgroup II from Musa basjoo in China.
