Genetic engineering of soybean trypsin inhibitor gene in groundnut (Arachis hypogaea L.) for induced resistance to insect pestsTShashi RekhaauthorBy using various concentrations of auxins and cytokinins it was found that 3 mg/L BAP+lmg/L NAA is ideal for regeneration of the leaflet explants of groundnut.Transformation of the leaflet explants of groundnut with soybean trypsin inhibitor (SBTI) gene had been done through Agrobacteriwn.The leaflet explants of groundnut had also been transformed with SBTI gene through Biolistics.The putatively transformed leaflet explants were assayed histochemically for the presence of this gene in the transformants.Groundnut1999University of Calicut;Department BiotechnologyThesis
