Parallel clines of chromosomal inversion frequencies in seaweed flies are associated with thermal variation Open
Chromosomal inversion supergenes, which form blocks of linked genes, are increasingly recognized for their role in maintaining intra-specific diversity. They are predicted to be relevant genetic architectures for local adaptation in the fa…

Evolution of crop phenotypic spaces through domestication Open
Summary We used domestication as an in vivo replicated experiment to investigate how divergent selection has shaped the evolution of multivariate phenotypic spaces. We measured 11 to 57 qualitative and quantitative traits in 13 species, ei…

Estimating the reduction in genetic diversity from background selection under non-equilibrium demography and partial selfing Open
The effect of natural selection on linked sites has been suggested to be a major determinant of genetic diversity. While it is in principle possible to estimate this effect from genome sequence data, interactions between selection, demogra…

Mating system and the evolution of recombination rates in seed plants Open
Meiotic recombination is a central mechanism underlying sexual reproduction among eukaryotes. In many species, the recombination rate is strongly constrained by chromosome size, as the number of crossovers per chromosome generally ranges b…

Diversity in Recombination Hotspot Characteristics and Gene Structure Shape Fine-Scale Recombination Patterns in Plant Genomes Open
During the meiosis of many eukaryote species, crossovers tend to occur within narrow regions called recombination hotspots. In plants, it is generally thought that gene regulatory sequences, especially promoters and 5′ to 3′ untranslated r…

Mating systems and recombination landscape strongly shape genetic diversity and selection in wheat relatives Open
How and why genetic diversity varies among species is a long-standing question in evolutionary biology. Life history traits have been shown to explain a large part of observed diversity. Among them, mating systems have one of the strongest…

Polygenic selection to a changing optimum under self–fertilisation Open
Many traits are polygenic, affected by multiple genetic variants throughout the genome. Selection acting on these traits involves co–ordinated allele–frequency changes at these underlying variants, and this process has been extensively stu…

An angiosperm-wide perspective on reproductive strategies and floral traits Open
Summary Flowering plants have many different modes of sexual reproduction, notably varying from selfing to outcrossing and from bisexual flowers to individuals with separate sexes (dioecy). These reproductive modes are associated with a ra…

Separating phases of allopolyploid evolution with resynthesized and natural Capsella bursa-pastoris Open
Allopolyploidization is a frequent evolutionary transition in plants that combines whole-genome duplication (WGD) and interspecific hybridization. The genome of an allopolyploid species results from initial interactions between parental ge…

Cosegregation of recombinant chromatids maintains genome-wide heterozygosity in an asexual nematode Open
In asexual animals, female meiosis is modified to produce diploid oocytes. If meiosis still involves recombination, this is expected to lead to a rapid loss of heterozygosity, with adverse effects on fitness. Many asexuals, however, have a…

The evolution from outcrossing to selfing occurred recently across the eukaryote tree of life in plants, animals, fungi, and algae. Despite short-term advantages, selfing is hypothetically an evolutionary dead-end reproductive strategy. Th…
