An efficient in vitro plant regeneration and Agrobacterium tumefaciens mediated genetic transformation protocol was described for castor (Ricinus communis L.) using meristem as explants. Shoot apex containing apical meristems were excised from 5-7 days old in vitro grown seedlings and cultured on Murashige and Skoog (MS) medium supplemented with different concentrations of cytokinins singly or in combination. Kinetin (0.50 mg/l) in combination with BAP (0.25 mg/l) produced maximum number of shoot (10.33) and shoot length (5.20 cm). For root induction, in vitro produced shoots were transferred to rooting media containing ? MS basal media with NAA. In Agrobacterium tumefaciens mediated genetic transformation, Agrobacterium tumefaciens strain containing construct pBIN1F harboring nptII and cry1F gene was used. The integration of the gene was confirmed by using PCR. The transformation experiment was performed by optimizing age of the seedlings and co-cultivation duration with...
