The complete sequence of two Cowpea aphid-borne mosaic virus (CABMV) isolates (RR3 and RR4) from India was determined. Phylogenetic analysis showed that both isolates showed different closeness with other isolates of CABMV. CABMV-RR3 showed maximum identity of 99 % with CABMV-BR1 from Brazil at nucleotide and protein levels, whereas CABMV-RR4 showed identity of 73 and 95 % with CABMV-Z isolate from Zimbabwe at nucleotide and protein levels respectively. Similarity identity matrix revealed 69 % identity at nucleotide level and 91 % at protein level with each other. Recombination breakpoint detection showed that CABMV-MG-Avr from Brazil and CABMV-Z from Zimbabwe act as major parents in our isolates RR3 and RR4, respectively.
