Two strains of whitefly-transmitted cowpea mild mottle virus (CPMMV) causing severe (CPMMV-S) and mild (CPMMV-M) disease symptoms in groundnuts were collected from 2 distinct agro-ecological zones in India. The host-range of these strains was restricted to Leguminosae and Chenopodiaceae, and each could be distinguished on the basis of symptoms incited in different hosts. The 3'-terminal 2500 nucleotide sequence of the genomic RNA of both the strains was 70% identical and contained 5 open reading frames (ORFs). The first three (P25, P12 and P7) overlapped to form a triple gene block of proteins, P32 encoded the coat protein, followed by P12 protein located at the 3' end of the genome. Genome organization and pair-wise comparisons of amino acid sequences of proteins encoded by these ORFs with corresponding proteins of known carlaviruses and potexviruses suggested that CPMMV-S and CPMMV-M are closely related to viruses in the genus Carlavirus. Based on the data, it is concluded that CPMMV is a distinct species in the genus Carlavirus.
