This study analyzes ancient U/V sex chromosomes in Polytrichaceae mosses, showing that recombination suppression has limited SDR expansion and functional degeneration despite their 124 million-year-old origin.

The paper genotypes the self-incompatibility locus in Brassica insularis using NGS methods, identifying S-alleles and showing low compatibility in a small population.

The paper investigates whether sporophytic self-incompatibility breaks down more easily in tetraploid compared to diploid populations, finding that dominance relationships significantly influence this outcome.

The paper shows autopolyploidy reduces heterozygosity at self-incompatibility loci under dominance masking, using Arabidopsis species data.

This study investigates how selfing rates and pollen limitation affect tetraploid establishment under gametophytic self-incompatibility.

The paper investigates sRNA precursors at the Arabidopsis self-incompatibility locus, showing they repress recessive alleles through non-canonical pathways and generate diverse sRNA molecules.

The paper analyzes the genomic structure and evolution of the S-locus in apple to show how balancing selection maintains conserved S-haplotype architectures despite structural divergence.

The paper identifies a hemizygous genomic region containing a gibberellin pathway gene that controls self-incompatibility in Oleaceae plants, linking GA catabolism to SI responses.

This study compares the accumulation of linked deleterious mutations between dominant and recessive S-alleles in Arabidopsis species under balancing selection.

The paper finds that genetic exchange is more frequent between animal species than plant species at the same level of genetic divergence, suggesting faster establishment of species barriers in plants.

The paper examines the genetic load linked to the self-incompatibility locus in Arabidopsis species, finding limited genomic influence of balancing selection on linked regions.

This paper provides a statistical framework using approximate Bayesian computation to infer demographic history in tetraploid species, accounting for complexities introduced by polyploidization and gene flow.

The paper investigates base-pairing requirements for small RNA-mediated gene silencing of recessive self-incompatibility alleles in Arabidopsis halleri using controlled crosses and RT-qPCR.
