S-RNases and sexual incompatibility: structure, functions, and evolutionary perspectives.

Molecular phylogenetics and evolution - 1 Dec 2003

Roalson Eric H, McCubbin Andrew G

Abstract excerpt

S-RNase-based gametophytic self-incompatibility appears to be the most phylogenetically widespread form of self-incompatibility found in the angiosperms, having been reported in the Solanaceae, Scrophulariaceae, and Rosaceae. This intraspecific breeding barrier is controlled by a single genetic locus termed S. Rejection of self-pollen has been shown to be mediated in the pistil by a highly polymorphic series of...
