Abstract

We determined the complete genomic sequence of begonia flower breaking virus (BFBV), a novel putative member of the genus Potyvirus isolated from Begonia bowerae cv. ‘Tiger’ plants grown in Kunming. The genomic RNA comprises 9540 nucleotides (nt), excluding the 3’-terminal poly(A) tail, and contains a typical open reading frame (ORF) of potyviruses. The ORF consists of 9219 nucleotides and encodes a 3073-amino-acid polyprotein that is predicted to be proteolytically cleaved into 10 mature peptides. Sequence comparison indicated that BFBV shares 43.9–55.12% amino acid sequence identity with known potyviruses and that BFBV shares the highest amino acid sequence identity (55.12%) with beet mosaic virus. The results from the complete genomic sequence analysis further suggest that BFBV is a member of a novel species in the genus Potyvirus.
