The population genetics of sporophytic self-incompatibility in three hybridizing senecio (asteraceae) species with contrasting population histories.

Evolution; international journal of organic evolution - 1 May 2013

Brennan Adrian C, Harris Stephen A, Hiscock Simon J

Abstract excerpt

Hybridization generates evolutionary novelty and spreads adaptive variation. By promoting outcrossing, plant self-incompatibility (SI) systems also favor interspecific hybridization because the S locus is under strong negative frequency-dependent balancing selection. This study investigates the SI mating systems of three hybridizing Senecio species with contrasting population histories. Senecio aethnensis and S....
