Transgenic in pulse crops: present scenario and future strategies uri icon

abstract

  • Transgenic techniques have made it possible to transfer any desirable gene from any organismto a plant species. Use of molecular biology techniques in combination with novel genetransfer technology has broadened the gene pool and crossed sexual crossability boundaries.Efforts are underway to produce transgenics having resistance genes to a variety of insectpestsand diseases using Agrobacrerium-mediated gene transfer or by direct DNA transfermethods. Transgenics possessing resistance to insect-pests have been demonstrated in plantsexpressing insecticidal genes such as S endotoxins from Bacillus thuringiensis (Bt), proteaseinhibitors, enzymes, secondary plant metabolites and plant leetins. Bt genes have been deployedin several crops on global basis while other alternative have received considerably lesspriority. While cereals, vegetables and commercial crops have received greater importance indeveloping transgenics, pulse crops like chickpea, pigeonpea, lentil, pea, cowpea, etc., havereceived considerably less attention. Keeping in view the regional importance of these crops,there is urgent need for development and deployment of transgenics for management ofHelicoverpa armigera. In this review current status of transgenics in pulses, particularlydealing with biotic has been discussed
