Genomic evidence of intraspecific recombination in sugarcane mosaic virus

Virus Genes volume 42, pages 282–285 (2011)Cite this article

Abstract

The sugarcane mosaic virus (SCMV) of the genus potyvirus, which primarily affects maize, sugarcane, sorghum, abaca, and grasses, occurs worldwide and causes significant economic loss. Using the full genome sequences of SCMV and several recombination detection methods, in this study we report that recombination is the major driving force in the evolution and emergence of several new variants of SCMV. We reported eight highly significant (P < 0.001) recombination break points, majority of which are located within 6K1-VPg-NIaPro-NIb region, thus indicating a region for recombination hotspot. The observation of commonalities of same recombination events among the SCMV isolates between the countries (Spain and Mexico), and within the country (within China, and within Mexico), suggests common origin of the isolates in respective regions.
