Bacterial CAT gene .with the 35S promoter of CaMV was transferred into leaf discs of cultivar Lycopersicon esculentum 462 with the help of Ti plasmid of Agrobacterium turnefaciens. These leaf discs were placed on MS salt and B5 vitamine medium containing kanamycin and carbenicillin. Several kinds of phytohormones were chosen in the medium, and it was found that zeatin and NAA have great effects on shooting and rooting. Transgenic tomato plants showed their normal flowering and fruiting. Leaves of these transgenic tomato plants were used for assaying the gene expression. Resuits of Southern Blot showed that the CAT gene was stably integrated into the genome of transgenic plants, The bacterial CAT, proteins were also detected, in transgenic tomato leaves with immunoreaction of CAT antibody. The methods presented here for culturing transformed tomato ceils will be a great help for transfering economically important genes into cultivars of tomato plants in China.
