The physicochemical properties and structure of an insect-resistant rice, Liangyou Kefeng Nr. 6 (IRR), containing the sck and cryIAc genes were compared with those of its nontransgenic counterpart designated as Liangyou 2186 (control), considering their key role in determining commercial value. Basically the appearance of IRR was not affected in terms of size and shape after foreign gene transf...
Forty homolog-scanning (double-reciprocal-crossover) mutant proteins of two Bacillus thuringiensis delta-endotoxin genes (cryIAa and cryIAc) were examined for potential structural alterations by a series of proteolytic assays. Three groups of mutants could be identified. Group 1, consisting of 13 mutants, showed no delta-endotoxin present during overexpression conditions in Escherichia coli (48...
Efforts are being made to express toxin genes from the bacterium, Bacillus thuringiensis (Bt) in chickpea for minimizing the losses due to the pod borer, Helicoverpa armigera. However, there is an apprehension that acidic exudates in chickpea leaves may influence the protoxin-toxin conversion in the insect midgut, and thus, reduce the efficacy of Bt toxins. Therefore, we studied the influence o...
