    The complete genome sequence of a Brazilian isolate of yambean mosaic virus (YBMV) is presented. High-throughput sequencing (Illumina HiSeq) and Sanger sequencing revealed the complete genome sequence of the YBMV-BRA-6 isolate, found in Canavalia ensiformis. The de novo contigs were assembled into a 9612 nucleotides (nt) long scaffold, excluding the 3'-terminal poly(A) tail, covering the complete genome. The genomic RNA contains an open reading frame (ORF) typical of members of the genus Potyvirus, family Potyviridae, encoding a large putative polyprotein of 3078 amino acids (aa) and a small overlapping PIPO ORF. Pairwise comparisons showed that the YBMV-BRA-6 isolate sequence shares 88.1% nt identity for the complete genome and 90.6% aa identity for the polyprotein with the YBMV-SR isolate. Phylogenetic analysis grouped both isolates together and close to bean common mosaic virus (BCMV). The polyprotein cleavage sites were predicted and a recombination event is described. © 2021.
