A sulfotransferase dosage-dependently regulates mouthpart polyphenism in the nematode Pristionchus pacificus

Abstract

Certain genotypes define developmental plasticity and discrete morphologies, but a mechanism as to how this arises is unclear. Here, the authors show that dosage-specific sulfotransferase (SEUD-1) expression specifies which mouthparts are expressed in the nematode Pristionchus pacificus, dependent on the environment.
