Complete genome sequence of melon yellowing-associated virus from melon plants with the severe yellowing disease in Brazil.
Here, we describe the complete genome sequence of melon yellowing-associated virus (MYaV), found in melon plants with severe yellowing disease, determined by high-throughput and Sanger sequencing. MYaV has an RNA genome of 9073 nucleotides plus a poly(A) tail. At least six open reading frames were predicted, with a typical carlavirus genomic organisation. Phylogenetic analysis of the complete genome sequence and the amino acid sequences of the RNA-dependent RNA polymerase confirmed that MYaV belongs to the genus Carlavirus, with the highest genome-wide nucleotide sequence identity of 59.8% to sweet potato yellow mottle virus.
