A system is described which uses an easily regenerated explant, the 3-to-4-day-old shoot apex, and Agrobacterium tumefaciens as the gene vector. Shoot apices were isolated, surface sterilized, and germinated on a Murashige and Skoog (MS) salts medium. Shoot apices were co-cultivated with different Agrobacterium tumefaciens strains, LBA4404, EHA101S and Z707S, containing genes for resistance to phosphinotricin (ppt) and hygromycin (hyg). After co-cultivation for 3 days in the light, shoot apices were transferred to the selective medium containing 10 mg/l ppt or 16 mg/l hyg formed roots on MS medium. The highest percentages of rooted plants on selective medium were obtained from shoots that were co-cultivated with Agrobacterium strain LBA4404. |
