Selection at Work in Self-Incompatible Arabidopsis lyrata: Mating Patterns in a Natural Population
Abstract Identification and characterization of the self-incompatibility genes in Brassicaceae species now allow typing of self-incompatibility haplotypes in natural populations. In this study we sampled and mapped all 88 individuals in a small population of Arabidopsis lyrata from Iceland. The self...
