Sorghum mosaic virus (SrMV), a causal agent of the destructive sugarcane mosaic disease, has a global presence. An isolate of SrMV infecting a commercially-grown sugarcane plant was recovered from the Hainan province of China. The virions were visualized by an electron microscope, and the coat proteins (CP) were sequenced by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and tandem mass spectrometry. Discrepancies between the CP predicted and actual amino acid sequences were noted, which confounded the phylogenetic assignment of the isolate. The apparent variations may have physiological effects on the pathogenicity and virulence of SrMV.
