Phylogeny and Genetic Divergence among Sorghum Mosaic Virus Isolates Infecting Sugarcane.

Sorghum mosaic virus (SrMV, the genus of the family ) is a causal agent of common mosaic in sugarcane and poses a threat to the global sugar industry. In this study, a total of 901 sugarcane leaf samples with mosaic symptom were collected from eight provinces in China and were detected via RT-PCR using a primer pair specific to the SrMV coat protein (). These leaf samples included 839 samples from modern cultivars ( spp.
