Parallel evolution of dominant pistil-side self-incompatibility suppressors in Arabidopsis
Abstract
In Brassicaceae, interaction between the pollen-derived peptide ligand SP11 and the pistil-expressed receptor kinase SRK leads to self-incompatibility. Here the authors provide evidence that in Arabidopsis dominant self-compatibility inducers evolved at least twice via insertion of inverted repeats in the SRK locus.
