Transgenic tobacco plants expressing synthetic CryIAc and Crylle genes are more toxic to cotton bollworm than those containing one gene 锕烟草中毒棉花螟蛉带Cry1Ac, Cry1Ie 或两基因的转基因的烟草植物被获得.在带两基因的转基因的植物的叶子, Cry1Ac 和 Cry1Ie 蛋白质的内容分别地是 0.173% 全部的蛋白...

We identify a cytochrome P450 gene (CYP6AE14) from cotton bollworm (Helicoverpa armigera), which permits this herbivore to tolerate otherwise inhibitory concentrations of the cotton metabolite, gossypol. CYP6AE14 is highly expressed in the midgut and its expression correlates with larval growth when...

coleopterans and dipterans. Bt cotton can resist cotton bollworm and produce higher yields. Cry gene produces cry protein or Bt toxin. It is an endotoxin which remains as protoxin in plants and converted to active toxin after getting ingested by the insects. Alkaline pH of the insect gut solu...

Gene encoding Bt protein specific for cotton bollworm is View Solution Study statement a-d (about organic farming) and find out the correct ones. (a) Utilises genetically modified crops like Bt cotton (b) Uses only naturally produced input like compost (c) Does not use pesticide and ...
quality (Mohan et al.2016). The polyphagus spotted bollworm is another serious pest and its internal feeding affects cotton bolls growth and development (Ahmed et al.2012). The severe invasion of army bollworm has drastic influence on cotton yield. Unfortunately, the effective control strategies ...
Further studies on the inserted point of bt gene may also provide valuable information. Most of varieties had similar Bt protein levels, with only a few showed higher expression. In recent years, some farmers found that the cotton transferred bt could not well resisted the cotton bollworm, ...
To gain new insights into these mechanisms, we performed multiple back-crossing from a 3000-fold Cry1Ac-resistant BtR strain from cotton bollworm (Helicoverpa armigera), isolating a 516-fold Cry1Ac-resistant strain (96CAD). Cry1Ac resistance in 96CAD was tightly linked to a mutant cadherin ...
