TL;DR: It is demonstrated that dominant and recessive S-haplotypes experience sharply contrasted patterns of molecular evolution, and that the S-locus presents many striking similarities with other regions involved in the determination of mating-types, such as sex chromosomes in animals or in plants, or the mating-type locus in fungi and green algae.

TL;DR: Phylogenetic analyses suggest that all species investigated evolved independently towards loss of self‐incompatibility, and in most cases almost intact sequences of either of the two S‐locus genes suggest that these transitions occurred relatively recently.

TL;DR: In this article, the authors uncover the evolution of how at least 17 small RNA-producing loci and their multiple target sites collectively control the dominance hierarchy among alleles within the gene controlling the pollen S-locus phenotype in a self-incompatible Arabidopsis species.

TL;DR: These findings suggest that the complete loss of SI in A. thaliana involved independent self-compatible mutants that arose prior to the last Ice Age, and experienced further rearrangements during postglacial colonization.
