High impact information on desat2

  • Taken together with previous molecular genetic evidence, our results suggest that ds2 is one of the genes responsible for adaptive divergence of the Z and M races of D. melanogaster [1].
  • To probe the role of natural selection in species origin, we performed a DNA polymorphism survey of the Drosophila melanogaster desaturase2 (ds2) locus. ds2 is responsible for a cuticular hydrocarbon difference between two behaviorally isolated races--Zimbabwe (Z) and Cosmopolitan (M) [1].
  • Several candidate genes, such as desaturase2 and Odorant receptor 63a, were additionally subjected to quantitative RT-PCR analysis [2].
