| interactions of bacillus thuringiensis cry1ac toxin in genetically engineered cotton with predatory heteropterans. | a number of cotton varieties have been genetically transformed with genes from bacillus thuringiensis (bt) to continuously produce bt endotoxins, offering whole plant and season-long protection against many lepidopteran larvae. constant whole-plant toxin expression creates a significant opportunity for non-target herbivores to acquire and bio-accumulate the toxin for higher trophic levels. in the present study we investigated movement of cry1ac toxin from the transgenic cotton plant through spec ... | 2008 | 17570072 |
