Exploitation of wild relatives of pigeonpea and chickpea for resistance to Helicoverpa armigera
Wild relatives continue to evolve in nature, and live by a different rule than the crop plants – which is survival of the fittest. Wild species have evolved to survive droughts, floods, extremes of heat and cold, and have the capability to withstand damage by insect pests and diseases that cause heavy damage to cultivated species. Many improved cultivars of crops are vulnerable to insect pests ...
متن کاملProtease Inhibitors in Wild Relatives of Pigeonpea against the Cotton Bollworm/Legume Pod Borer, Helicoverpa armigera
Cotton bollworm/legume pod borer, Helicoverpa armigera is one of the most damaging pests worldwide. Because of the difficulties associated with chemical control of this pest, emphasis has been placed on developing transgenic plants with resistance to H. armigera. Since toxin genes from the bacterium, Bacillus thuringiensis (Bt) have been deployed on a large scale, there is need to scout for alt...
متن کاملgenetic engineering for increasing resistance of chickpea (cicer arietinum l.) to pod borer (helicoverpa armigera)
pod borer is one of the main factors for yield decrease of chickpea. therefore, breeding of chickpea for resistance to this pest is important. modified cry1ac gene of bacillus thuringiensis in pcry1ac-nptii plasmid containing twin t-dna for cry1ac and nptii genes have been used for transformation of chickpea. at last 38 plants had nptii gene that 36 plants of them had cry1ac gene and two plants...
متن کاملUnderstanding Helicoverpa armigera Pest Population Dynamics related to Chickpea Crop Using Neural Networks
Insect pests are a major cause of crop loss globally. Pest management will be effective and efficient if we can predict the occurrence of peak activities of a given pest. Research efforts are going on to understand the pest dynamics by applying analytical and other techniques on pest surveillance data sets. In this study we make an effort to understand pest population dynamics using Neural Netw...
متن کاملDifferential Inhibition of Helicoverpa armigera (Hubner) Gut Proteinases by Proteinase Inhibitors of Okra and It's Wild Relatives
The seeds of ten genotypes and twenty-nine wild relatives of okra were analysed for the presence of trypsin, chymotrypsin, and Helicoverpa gut proteinases (HGPs) inhibitors (HGPIs), with the aim to identify potent inhibitors of H. armigera gut proteinases. Proteinase inhibitors (PIs) obtained from wild relatives of okra exhibited stronger inhibition of HGPs than the genotypes of okra. In in vit...
