Specialization of a polyphenism switch gene following serial duplications in Pristionchus nematodes.

Evolution; international journal of organic evolution - 1 Sept 2016

Ragsdale Erik J, Ivers Nicholas A

Abstract excerpt

Polyphenism is an extreme manifestation of developmental plasticity, requiring distinct developmental programs and the addition of a switch mechanism. Because the genetic basis of polyphenism switches has only begun to be understood, how their mechanisms arise is unclear. In the nematode Pristionchus pacificus, which has a mouthpart polyphenism specialized for alternative diets, a gene (eud-1) executing the...
