Protease 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 کاملExploitation 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 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 کاملUse of indices based on consumption and utilization of food as a criterion to evaluate putative transgenic pigeonpea plants for resistance to pod borer Helicoverpa armigera
The increasing need for food can be met through an increase in crop productivity and reduction in pest associated losses. Recombinant DNA technology has created new avenues for genetic enhancement of crops through the development of transgenic plants with resistance to insects. Bacillus thuringiensis (Bt) genes have been widely used as candidate genes for genetic transformation of crop plants f...
متن کاملA geometric morphometric study on geographical Iranian populations of the pod borer, Helicoverpa armigera (Lepidoptera: Noctuidae)
تصاویر بال جلو و عقب (به ترتیب دارای 15 و 12 لندمارک) 5 جمعیت جغرافیایی پروانه‌ی کرم غوزه‌ی پنبه، Helicoverpa armigera (Hübner)، از مناطق مختلف شمال و شمال غرب کشور مورد تجزیه و تحلیل چند متغیره قرار گرفت. تعداد 287 تصویر متعلق به بال جلو و 277 تصویر متعلق به بال عقب با استفاده از 26 متغیر ریخت‌سنجی هندسی در بال جلو و 20 کاراکتر در بال عقب با یکدیگر مقایسه شدند. آنالیز فاکتورهای مربوطه نشان داد...
