Abstract
Abstract The Hessian fly, Mayetiola destructor (Say), poses a significant economic threat to wheat in terms of reduced grain yield, particularly in the eastern soft-winter-wheat region of the United States. However, little is know about the molecular mechanisms involved in the plant-insect interaction. The glutathione S-transferases (GSTs) form a large family of enzymes that protect cells from damage by reactive electrophilic compounds. We have cloned and characterized two GST genes from biotype GP of the Hessian fly. Sequence analysis and homology searches of the coding region for the first gene (designated mdesgst1-1) indicated it contained an intact coding region for a GST-like protein sharing homology to the insect class I GSTs. Analysis of the coding region for the second gene indicated it contained numerous stops and was most probably a pseudogene. Southern analysis and in situ hybridization on polytene chromosomes suggested the class I GSTs in M. destructor are encoded by a small gene family that i...
