A tobamovirus was isolated from leaves of a Scopolia japonica plant showing mild yellowing. Back-inoculation of healthy Scopolia japonica with the isolated virus induced mild mottle on upper leaves. Phylogenetic analysis based on coat protein and replicase protein sequences revealed that the newly isolated tobamovirus was most closely related to yellow tailflower mild mottle virus (YTMMV). The newly isolated tobamovirus shared the highest nucleotide sequence identity (71%) with YTMMV, which is lower than the cutoff (90%) set for species demarcation in the genus Tobamovirus. Thus, our result suggested that scopolia mild mottle virus (SMMoV) is a new tobamovirus that infects Scopolia japonica plants in Japan.
