New Roots for Restoration: Building a foundation for interdisciplinary work in plant organismal biology and ecology to advance restoration in natural and agricultural ecosystems Open
Societal Impact Statement Soils are globally degraded due in part to conventional agriculture and wildland conversion. To address the global challenge of soil degradation, we formed an interdisciplinary, cross‐institutional collaborative r…

Natural selection drives emergent genetic homogeneity in a century-scale experiment with barley Open
Direct observation is central to our understanding of the process of adaptation, but evolution is rarely documented in a large, multicellular organism for more than a few generations. Here, we observe genetic and phenotypic evolution acros…

On the hidden temporal dynamics of plant adaptation Open
Adaptation to a wide range of environments is a major driver of plant diversity. It is now possible to catalog millions of potential adaptive genomic differences segregating between environments within a plant species in a single experimen…

Supergene potential of a selfish centromere Open
Selfishly evolving centromeres bias their transmission by exploiting the asymmetry of female meiosis and preferentially segregating to the egg. Such female meiotic drive systems have the potential to be supergenes, with multiple linked loc…

Sex-specific natural selection on SNPs in<i>Silene latifolia</i> Open
Selection that acts in a sex-specific manner causes the evolution of sexual dimorphism. Sex-specific phenotypic selection has been demonstrated in many taxa and can be in the same direction in the two sexes (differing only in magnitude), l…

Genome-wide association mapping of transcriptome variation in <i>Mimulus guttatus</i> indicates differing patterns of selection on <i>cis</i> - versus <i>trans</i> -acting mutations Open
We measured the floral bud transcriptome of 151 fully sequenced lines of Mimulus guttatus from one natural population. Thousands of single nucleotide polymorphisms (SNPs) are implicated as transcription regulators, but there is a striking …

How rapidly do self‐compatible populations evolve selfing? Mating system estimation within recently evolved self‐compatible populations of Azorean <i>Tolpis succulenta</i> (Asteraceae) Open
Genome‐wide genotyping and Bayesian inference method (BORICE) were employed to estimate outcrossing rates and paternity in two small plant populations of Tolpis succulenta (Asteraceae) on Graciosa island in the Azores. These two known exta…

Severe inbreeding depression is predicted by the “rare allele load” in<i>Mimulus guttatus</i>* Open
Most flowering plants are hermaphroditic and experience strong pressures to evolve self-pollination (automatic selection and reproductive assurance). Inbreeding depression (ID) can oppose selection for selfing, but it remains unclear if ID…

On the nature of genetic variation in yellow monkeyflower (Mimulus guttatus): combining theoretical and empirical approaches Open
Evolution via natural selection requires standing variation in a population while simultaneously diminishing it at loci under selection, a paradox that continues to vex evolutionary biologists. The work presented here contributes to our un…

Antagonistic pleiotropy can maintain fitness variation in annual plants Open
Antagonistic pleiotropy ( AP ) is a genetic trade‐off between different fitness components. In annual plants, a trade‐off between days to flower ( DTF ) and reproductive capacity often determines how many individuals survive to flower in a…

The genetic breakdown of sporophytic self‐incompatibility in <i>Tolpis coronopifolia</i> (Asteraceae) Open
Summary Angiosperm diversity has been shaped by mating system evolution, with the most common transition from outcrossing to self‐fertilizing. To investigate the genetic basis of this transition, we performed crosses between two species en…
