Abstract

An efficient and reproducible in vitro regeneration protocol was developed with high frequency regeneration of shoot buds from shoot-tip in MS medium + BAP (2.0 mg/l) in Brinjal cv. Utkal Anushree. Rooting was obtained on MS medium+ NAA (0.01 mg/l). The Agrobacterium tumefaciens strain GV3107 containing a binary vector pCAMBIA2300 carrying rd29A::DREB1A gene has been used for transformation. The shoot-tip from in vitro grown seedling was pre-cultured for 72 hrs and co-cultivated for 24 hrs. Shoot buds were produced on the regeneration medium containing kanamycin (100 mg/l) and cefotaxime (250 mg/l). A transformation frequency of 6.40% was achieved after PCR analysis with gene specific primer. The gene expression for moisture stress tolerance was assessed through morpho-physiological and biochemical analyses.
