Agrobacterium rhizogenes-mediated Transformation and Regeneration of the Apocynum venetum
چکیده انگلیسی
A system for the Agrobacterium rhizogenes-mediated transformation and plant regeneration of A. venetum has been developed. The highest transformation frequency was 100%, achieved using strain LBA9402 with root explants. The highest density of hairy roots reached 22 when root explants transformed by R1000 cultured in the dark. Adventitious shoots were obtained from profusely branched, fast-growing (type PBF) hairy roots, and the adventitious shoot induction frequency was 20%. Regenerated shoots rooted easily on hormone-free ½ MS solid medium in 2 weeks. Approximately 1/3 regenerated plants derived from hairy roots exhibited prolific roots with shortened internodes, whereas other regenerated plants showed another phenotype: long internodes, strong stems, and fleshy blades. However, all regenerated plants displayed a relatively fast development procedure and stronger than the aseptic seedlings. Polymerase chain reaction (PCR) analyses confirmed that the hairy root lines and regenerated plants were induced by A. rhizogenes.
