Genetic diversity and molecular evolution of sugarcane mosaic virus, comparing whole genome and coat protein sequence phylogenies.

ABSTRACT: Sugarcane mosaic virus (SCMV) is a widely distributed potyvirus that causes mosaic disease in sugarcane, maize, sorghum, canna, and other monocot species worldwide. This study used 139 SCMV full-length genome sequences to analyze the phylogenetic relatedness of geographically distinct isolates. The phylogenetic analysis revealed four major groups of SCMV isolates that relate to their primary host. The geographic locations for some isolates appear to be mismatched within the tree, suggesting either that convergent molecular evolution has occurred or that the tree reconstruction produces statistically significant incongruences that create uncertainty in the true evolutionary relationships of these virus isolates. Recombination analysis showed hot spots across most of the genome except in the
