In order to optimize genetic transformation system for Anthurium andraeanum, leaves of cultivar Arizona plantlets was used as explants and the recombinant plasmid p SN1301- HYG- Ph CHS was transferred to A. andraeanum cv.Arizona mediated by Agrobacterium tumefaciens GV3101. The efficient transformation system for A.andraeanum cultivar Arizona was described as follows: Leaves were cut and pre-cultured for 3d on the 1/3 MS cult...
