Abstract:
The leaf sample from soybean plants showing the yellow vein mosaic disease symptoms was collected in New Delhi, India. The genome of the virus was amplified, cloned and sequenced. Sequence analysis revealed that the viral genome is 2747 nucleotides in length and genome is similar to that of monopartite begomoviruses originating from the Old World, with seven conserved ORFs. Further nucleotide (nts) sequence comparisons showed that the genome has the highest sequence identities of 99% the same as the sequence that had already been reported. These results suggested that the isolates are a strain of MYMIV also strongly associated with the whitefly population emerging during Kharif season in the year 2018. The isolates have obtained from sources like plant and whitefly having closely related with each other in isolated during initial period of Kharif from whiteflies and final period being considered for isolating from soybean tissue. In the study we have proved that insect vector bringing primary inoculum.
