Tobacco ringspot virus (TRSV) is an important plant pathogen that causes severe diseases in tobacco plants. In recent years, this virus has been reported in a number of ornamental plants. However, it has never been reported from Japanese iris, a famous traditional ornamental plant distributed in Asian countries. In this study, the near-complete bipartite genome of a nepovirus (TRSV-Iris) infecting Japanese iris from Taiwan of China was determined. The RNA1 and RNA2 are 7512 and 3899 nucleotides in length, and encodes a polyprotein of 2303 and 1078 amino acids, respectively. Sequence analysis indicates that TRSV-Iris shares more than 80% amino acid sequence identity, the threshold values of the species demarcation for the genus Nepovirus, with known TRSV isolates either in the conserved Pro-Pol or CP regions, respectively. Phylogenetic analysis indicates that TRSV-Iris is a TRSV isolate.
