Erratum to: Genome analysis of a severe and a mild isolate of Papaya ringspot virus-type W found in Brazil

Papaya ringspot virus (PRSV) has a single-stranded RNA genome and causes severe economic losses both in cucurbits and papaya worldwide. The extent to which the genome of PRSV is shaped by recombination provides an understanding of the molecular evolution of PRSV and helps in studying features such as host specificity, geographic distribution, and its emergence as new epidemics. The PRSV-P-Indian isolate was completely sequenced and compared with 14 other isolates reported from the rest of the world for their phylogenetic survey of recombination events. Cistron-by-cistron sequence comparison and phylogenetic analysis based on full-genome polyprotein showed two distinct groupings of Asian and American isolates, although PRSV-P and W-India clustered along with the American isolates. Recombination sites were found throughout the genomes, except in the small 6K1 protein gene. A significant proportion of recombination hotspots was found in the P1 gene, followed by P3, cylindrical inclusion (CI), and helper component proteinase (HcPro). Correlations between the presence of recombination sites, geographic distribution, and phylogenetic relationship provide an opportunity to establish the molecular evolution and geographic route of PRSV.
