Abstract Development of transgenic Bt crops with stable and high level of Bt protein
expression over generations under different environmental conditions is critical for …

A chimeric Bacillus thuringiensis toxin (Bt) gene, cry2AX1was cloned in a bi-selectable
marker free binary vector construct. The cry 2AX1 gene, driven by the Chrysanthemum rbc …

The global agricultural production needs to go up by 70% until 2050, to keep pace with ever-
increasing human population and is a major challenge of this century. Green revolution and …

Bacillus thuringiensis is a major source of insecticidal genes imparting insect resistance in
transgenic plants. Level of expression of transgenes in transgenic plants is important to …

Transgenic cotton plants expressing a novel cry2AX1 gene consisting of sequences from the
cry2Aa and cry2Ac genes, driven by the CaMV35S or the EnCaMV35S promoters, were …

The insecticidal cry genes of Bacillus thuringiensis (Bt) have been successfully used for
development of insect resistant transgenic rice plants. In this study, a novel cry2AX1 gene …

Resistance breeding programs resulted in the successful development of rice cultivars
expressing resistance to major insect pests of rice. However, the conventional breeding …

Embryogenic calli of cotton (Coker310) were cocultivated with the Agrobacterium
tumefaciens strain LBA4404 harbouring the codon-optimised, chimeric cry2AX1 gene …

Mutagenesis gives an avenue of possibilities for developing improved cultivars in crops with
limited or no variability in a specific trait. Mutagenesis has been used in plant breeding to …

Tomato (Solanum lycopersicum) is one of the world's most preferred vegetable crops. The
growth and productivity of tomato crop is often hampered by various biotic as well as abiotic …
