A stable, efficient, and reliable selection system using bar and hpt as selectable markers for Agrobacterium mediatedco-transformation of rice with two separate vectors was developed. Two plasmids, pMJC-GB-IFS2 and pMJC-GH-CHR carryingbar or hpt gene as s

The coat protein (CP) gene of the G5H and G7H strains of Soybean mosaic virus (SMV) were cloned, sequenced and transformed into the tobacco plant (Nicotiana tabacum. cv. Havana SR1) via Agrobacterium-mediated transformation. Transformation was confirmed b
