摘要: Tryptophan decarboxylase (TDC) from Catharanthus roseus (periwinkle) converts tryptophan to the indole-alkaloid tryptamine. When TDC gene was expressed in transgenic tobacco, 55-kD enzyme and tryptamine accumulated. Bemisia tabaci (sweetpotato whitefly) reproduction on plants decreased up 97% relative controls. Production of tryptamine, its derivatives, or other products resulting activity may discourage whitefly provide a single-gene-based plant protection strategy.
