The structural similarity of all members of the family of three-domain Bt toxins and the separate roles of the domains in the processes of receptor binding and channel formation suggested that combining domains from different proteins could generate active toxins with novel specificities. Protein engineering not only reveals the mechanism by which endotoxins work, but it can generate toxins with enhanced toxicity/introduce a specific activity into a toxin that does not possess it. Evolution of resistance to more than one toxin is associated with the alteration of a common binding site in...

Plant yield and quality are complex characters depending upon a number of genetic factors interacting with the environment. The development of superior variety is based on magnitude of genetic variability in the base population and extent of heritability of desired character. The limited variability in durum wheat owing to its evolutionary history is of great concern in improving its yield potential. Yield enhancement could be obtained indirectly by improving yield components which are controlled by a number of genes with small additive effect which are called as Quantitative Trait Loci...
