Establishment of an efficient transformation system is a prerequisite for genetic improvement of Jatropha curcas, a promising biodiesel feedstock plant, by transgenic approach. In this study an efficient Agrobacterium-mediated transformation protocol using cotyledon explants from J. curcas seeds was developed. The integration and expression of the transgenes in the putatively transformed J. curcas plants was confirmed by polymerase chain reaction (PCR), Southern blot analysis and β-glucuronidase (GUS) activity staining. In the protocol used, the critical step for successful transformation is that the selective agent kanamycin (20 mg/L) is not included in the callus-inducing medium within the first 4 weeks after co-cultivation with Agrobacterium.
