Calli were induced from leaves of tea cultivar 'Nongkangzao',and those growing vigorously with compact tissue were chosen for agrobacterium-mediated transformation by EHA105.The transgenic callus was screened using hygromycin.The resistant callus was confirmed by RT-PCR and GUS dyeing.The results showed that transgenic callus was obtained using this method,and the conversion rate was about 10% after adding 100 μmol·L-1 acetosyringone(AS).The results also showed that the efficiency of agrobacterium-mediated ...
