Identification and molecular characterization of a novel totivirus from Mangifera indica.

Abstract

In this study, we determined the complete genome sequence of a novel totivirus, tentatively named "Mangifera indica totivirus 1" (MiTV1), identified in 'Apple' mango in China. The double-stranded RNA genome of MiTV1 is 4800 base pairs (bp) in length and contains two open reading frames (ORFs) encoding a putative coat protein (CP) and an RNA-dependent RNA polymerase (RdRp). Phylogenetic analysis based on RdRp and CP amino acid sequences showed that MiTV1 is closely related to members of the genus Totivirus in the family Totiviridae. To our knowledge, this is the first report of a totivirus found in Mangifera indica.
