Genetic transformation of pigeonpea with rice chitinase gene uri icon

abstract

  • With a long-term plan to develop transgenic pigeonpea with resistance to fungal disease, the transfer of a rice chitinase gene to pigeonpea(Cajanus cajan (L.) Millsp.) is reported here. The rice chitinase geneharboured in the plasmid pCAMBIA 1302:RChit was delivered via the Agrobacterium-mediated method to the cotyledonary node explants followed by subsequent regeneration of complete plants on selection media containing hygromycin. Putative transformed pigeonpea plants were recovered with stringent selection pressure and confirmed usingmolecular techniques. Stable integration and expression of the chitinase gene has been confirmed in the T0 and T1 transgenics through molecular analysis
