Genetic Transformation of Crops for Insect Resistance: Potential and Limitations
|
Transgenic resistance to insects has been demonstrated in plants expressing insecticidal genes such as 5-endotoxins from Bacillus thuringiensis (Bt), protease inhibitors, enzymes, secondary plant metabolites, and plant lectins. While transgenic plants with introduced Btgenes have been deployed in several crops on a global scale, the alternative genes have received considerably less attention. The protease inhibitor and lectin genes largely affect insect growth and development and, in most ins...

Biotechnological Prospects for Engineering Insect-Resistant Plants1[C]
Plant Physiology
; Insect-resistant crops have been one of the major successes of applying plant genetic engineering technology to agriculture; cotton (Gossypium hirsutum) resistant to lepidopteran larvae (caterpillars) and maize (Zea mays) resistant to both lepidopteran and coleopteran larvae (rootworms) have become

Genetic Engineering with Bacillus thuringiensis and Conventional Approaches for Insect Resistance in Crops
Critical Reviews in Plant Sciences
; The aim of resistance management is to slow and ideally reverse the development of resistance in the pest population. Since 1996, million of acres of crops have been planted that are genetically engineered with Bacillus thuringiensis (Bt) for insect resistance. The novelty for resistance management
