Biological and Molecular Characterization of Two Distinct Tomato Strains of Cucumber mosaic virus Based on Complete RNA-3 Genome and Subgroup Specific Diagnosis.

ABSTRACT: Cucumber mosaic virus (CMV) is one of the most important viral pathogen infecting several plant species in India. Five isolates of CMV obtained from cucumber, muskmelon, tobacco and tomato from distinct geographical locations in India were analysed based on host-reactions and genome sequence. The majority of the isolates were very similar and only two isolates, Tfr-In and Tss-In showed distinct symptoms in tomato and high sequence diversity (77.8%) in coat protein (CP) gene. Tfr-In was isolated from tomato fruit showing grey patches in Aurangabad and Tss-In from tomato plant showing shoe-string symptoms in New Delhi. The RNA-3 genomes of Tfr-In (2,214 nt; JF279606), shared only 70.3% nucleotide sequence identity with Tss-In (2,178 nt; JF279605. The complete RNA-3 genome of Tss-In and Tfr-I
