Specific Incorporation of L-Glutamine into Volicitin in the Regurgitant of Spodoptera litura(Organic Chemistry)

概要

Volicitin, [N- (17-hydroxylinolenoyl) -L-glutamine], was identified as an elicitor of plant volatiles from a Spodoptera exigua regurgitant. It has been proposed that gut microbes synthesize volicitin from glutamine, a predominant amino acid component in the insect gut. However, we found that glutamine was not a major component in the regurgitant of Spodoptera litura, although L-glutamine was exclusively incorporated into volicitin by S. litura fed on diets enriched with various amino acids. This selectivity of glutamine as a substrate was not due to a dominant occurrence in the insect gut.
