The Gram-positive bacterium Bacillus thuringiensis produces proteins which are specifically toxic to a variety of insect species. Modified genes have been derived from bt2, a toxin gene cloned from one Bacillus strain. Transgenic tobacco plants expressing these genes synthesize insecticidal proteins which protect them from feeding damage by larvae of the tobacco hornworm. 
Transgenic Cabbage Plants with Insect Tolerance
An insecticidal crystal gene of Bacilllus thuringiensis fused to a modified CaMV 35S promoter was used to construct a binary vector which was transferred into Agrobacterum tumefacueus with disarmed
Can Insect Pest Problems in Rice be Approached by Using Bacillus Thuringiensis Crystal Protein Genes
During recent years several procedures have been developed to introduce foreign genes into plant cells and to subsequently regenerate fertile plants, one example being the engineering of plants resistant to insect attack through the expression of insecticidal proteins.
Managing Insect Resistance to Bacillus thuringiensis Toxins
Bacillus thuringiensis δ-endotoxins provide an alternative to chemical insecticides for controlling many species of pest insects and the discovery that insects can adapt to these toxins raises concerns about the long-term usefulness of B.t. toxins.
Transforming Plants as a Means of Crop Protection against Insects
The progress which is being made towards producing crops which naturally resist their insect pests by introducing insect control genes into crops by plant genetic engineering is reviewed.
Transgenic sugarcane plants resistant to stem borer attack
A truncated cryIA(b) gene encoding the active region of the Bacillus thuringiensis δ-endotoxin was expressed in transgenic sugarcane plants under the control of the CaMV 35S promoter and showed significant larvicidal activity despite the low expression of CryIA( b).
