Genetic Manipulation of Tomato (Solanum lycopersicum) cv. PKM-1 using cry2AX1 Gene for Insect Resistance

Study of Expression of Indigenous Bt cry2AX1 Gene in T3 Progeny of Cotton and its Efficacy Against Helicoverpa armigera (Hubner)

“…A synthetic cry2AX1 gene (NCBI accession number GQ332539.1) was codon optimized to express in plants and it was used to generate insect resistant transgenic cotton plants. Expression of Cry2AX1 protein in rice and tomato showed significant mortality of target insect species [17][18][19]. In T0 generation, the cry2AX1 transgenic cotton event, CH12 (one of the best performing event) showed 88 % mortality in H. armigera with the Cry2AX1 concentration of 1.0 µg/g of fresh leaf tissue [20].…”
