Abstract: | The seed lipids of some higher plants contain unusual fatty acids with potentially valuable non-food uses. Seeds of Bassia scoparia contain one such monounsaturated fatty acid, 16:1Delta5. This fatty acid can be used for the production of an insect oviposition pheromone, which is potentially valuable in the control of the mosquito Culex quinquefasciatus, a vector of West Nile virus. Previous work has established that a number of unusual monounsaturated fatty acids are produced by variant forms of the ubiquitous acyl-ACP desaturases. The isolation and initial characterization of two putative acyl-ACP desaturases from B. scoparia, one of which is seed-specific, suggests that such a variant enzyme occurs in this species. |
