Population genomics reveals demographic history and climate adaptation in Japanese Arabidopsis halleri

This study uses population genomics to analyze climate adaptation and demographic history in Japanese Arabidopsis halleri, revealing genetic differentiation and selection signatures linked to climate variables.

The diallelic self-incompatibility system in Oleaceae is controlled by a hemizygous genomic region expressing a gibberellin pathway gene

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.

The genetic architecture of the load linked to dominant and recessive self-incompatibility alleles in Arabidopsis halleri and A. lyrata

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

Dominance between self-incompatibility alleles determines the mating system of Capsella allopolyploids

This study shows that dominance between self-incompatibility alleles determines the mating system of allopolyploid Capsella species.

Genetic mapping of sex and self-incompatibility determinants in the androdioecious plant Phillyrea angustifolia

The paper develops a high-density genetic map for Phillyrea angustifolia to study sex and self-incompatibility (SI) determinants, finding single Mendelian factors for each trait.

Balancing selection and the crossing of fitness valleys in structured populations: diversification in the gametophytic self-incompatibility system

This study uses simulations to show population structure can both increase and risk loss of S-haplotypes in self-incompatibility systems.

Maintenance of adaptive dynamics and no detectable load in a range-edge out-crossing plant population

The paper examines a range-edge population of Arabidopsis lyrata ssp petraea and finds it maintains adaptive dynamics and no detectable fitness load despite genetic drift and increased genomic burden of deleterious mutations.

A New Tree-Based Methodological Framework to Infer the Evolutionary History of Mesopolyploid Lineages: An Application to the Brassiceae Tribe (Brassicaceae).

This paper introduces a tree-based method to infer the evolutionary history of mesopolyploid lineages, applied to the Brassiceae tribe, resolving phylogenetic relationships among species and parental lineages.

High throughput, high fidelity genotyping and de novo discovery of allelic variants at the self-incompatibility locus in natural populations of Brassicaceae from short read sequencing data

The paper develops a method to genotype and discover new alleles at the self-incompatibility locus in Brassicaceae using short read sequencing data from natural populations.

Asymmetrical diversification of the receptor-ligand interaction controlling self-incompatibility in Arabidopsis

The paper shows how two receptor-ligand variants in Arabidopsis self-incompatibility diverged asymmetrically, with one retaining ancestral specificity and the other evolving a novel one.

Breakdown of gametophytic self-incompatibility in subdivided populations

The paper shows that population subdivision reduces SI maintenance by decreasing local SI allele diversity, using simulations and analytical models.

Genetic basis and timing of a major mating system shift in Capsella

This study identifies a dominant loss-of-function mutation in the male self-incompatibility gene SCR as the cause of a recent shift to self-fertilization in Capsella orientalis.

Differential retention of transposable element-derived sequences in outcrossing Arabidopsis genomes

The paper compares TE dynamics in two Arabidopsis species, finding that orthologous TE insertions are closer to genes, less methylated, and less expressed than non-orthologous ones.

Patterns of polymorphism at the self-incompatibility locus in 1,083 Arabidopsis thaliana genomes

The paper analyzes polymorphism at the S-locus in 1,083 Arabidopsis thaliana genomes to understand the historical loss of self-incompatibility, finding multiple independent origins and recombination events during post-glacial colonization.
