Comparative analysis of the genomes of two isolates of cowpea aphid-borne mosaic virus (CABMV) obtained from different hosts

The complete genomic sequences of two cowpea aphid-borne mosaic virus (CABMV) isolates from Brazil, MG-Avr from passion fruit (which also infects cowpea), and BR1 from peanut (which also infects cowpea, but not passion fruit), were determined. Their nucleotide sequences are 89% identical and display...

Description
Summary:The complete genomic sequences of two cowpea aphid-borne mosaic virus (CABMV) isolates from Brazil, MG-Avr from passion fruit (which also infects cowpea), and BR1 from peanut (which also infects cowpea, but not passion fruit), were determined. Their nucleotide sequences are 89% identical and display 85% identity to that of CABMV-Z. Both isolates have the typical potyvirus genome features. P3 and VPg are the most conserved proteins, with 99% amino acid sequence identity between the two isolates, and P1 is the most variable, with 50% identity. A significant variation exists at the 5’-end of the genome between the Brazilian isolates and CABMV-Z. However, this variation does not correlate with the biological properties of these three isolates.
