CHARACTERIZATION OF AN INDIAN ISOLATE OF COWPEA APHIDBORNE MOSAIC VIRUS
R. Mishra, R.K. Verma, R.K. Gaur
Cowpea aphid-borne mosaic virus (CABMV) infects cowpea and some non-legume plant species (Chenopodium amaranticolor) worldwide, including India. The genome of CABMV RR4, an Indian viral isolate, consists of a positive-sense RNA molecule 9,159 nucleotide in size encoding a single polyprotein of 3,053 amino acids. The nucleotide sequence of CABMV RR4 genome showed the highest identity of 73% and 95% with CABMV-Z isolate from Zimbabwe at the nucleotide and polyprotein level, respectively. The phylogenetic analysis of CABMV RR4 showed the ancestry and evolutionary relationship with CABMV-Z and CABMV-A132 isolates.
