Abstract
In this study, the full-length components of mungbean yellow mosaic India virus (MYMIV) DNA-A (MW590720 & MW600934) and DNA-B (MW659819 & MW659820) from a soybean isolate were cloned and sequenced. Nucleotide sequence analysis of both MYMIV components revealed > 96% identity and close ancestry with MYMIV isolates from legumes in Southeast Asia. Furthermore, dimeric infectious clones of MYMIV were generated in the pCAMBIA1302 vector, and a seed infiltration protocol was established for mungbean, soybean, and Nicotiana tabacum. Agroinfiltration induced yellow mosaic symptoms in mungbean and N. tabacum plants 3 weeks post-infiltration, which were further confirmed by PCR using MYMIV-specific DNA primers.
