Genetic modification 38 insecticides

ECPA is the pan-European voice of the crop protection industry. The membership includes both national associations and companies throughout Europe, including Central and Eastern Europe. In addition to traditional crop protection products such as herbicides, fungicides and insecticides, our members also provide biopesticides and genetically modif ied crops. [Pg.257]

It can be envisioned that besides the intended effects of a genetic modification, such as the expression of an insecticidal protein, the modification may also have brought about unintended effects. This may relate, for example, to the insertion of the newly introduced DNA into an intrinsic gene ofthe recipient organism. Also interactions of introduced enzymes with pre-existing biochemical pathways, such as competition for common precursors, can in some theoretical cases be envisioned. [Pg.367]

Acetylcholinesterase inhibition has been widely used for pesticide detection [88-94], but less exploited than protein phosphatase inhibition for cyanobacterial toxin detection. Nevertheless, the anatoxin-a(s) has more inhibition power than most insecticides, as demonstrated by the higher inhibition rates [95]. In order to detect toxin concentrations smaller than usually, mutant enzymes with increased sensitivity were obtained by genetic engineering strategies residue replacement, deletion, insertion and combination of mutations. Modifications close to the active site, located at the bottom of a narrow gorge, made the entrance of the toxin easier and enhanced the sensitivity of the enzyme. [Pg.344]
