%X Excised cotyledons of Orychophragmus violaceus, were used as explants for tissue culture. They were cultured on MS medium supplemented with BA 3 mg/L and NAA 0. 2mg/L. When the regenerated buds were 2cm long, they were excised and transferred onto 1/2MS medium with IBA 0. 03mg/L, then the whole planticts were regenerated . The frequency of plant regenration was 100%. Then we began to study the genetic transformation of O. violaceus, After 2-3 days of cocultivation with Agrobacteri-um tumefaciens strain A208se (pTiT37 pROA93), the cotyledons were transferred onto the selection medium containing 25mg/L Km and 250mg/L Ap. After shoots emerged, they were excised and transferred onto the root medium containing 25mg/L Km and 100mg/L Cef, the roots were formed within 4-5 weeks. The whole plants were transplanted into pots and grew well. The frequency of plant regeneration was about 51%. The regenerated plants showed high enzymatic activities of B-glucuronidase and neomycine phosphotransferase I . Southern blot analysis confirmed that NPT I gene had been stably integrated into the chomosomal genome of O. violaceus. The transformation frequency was 5. 6%. In this paper, the first transgenic plant of O. violaceus is being reported.
