The effect of autopolyploidy on population genetic signals of hard sweeps
1. Introduction Whole genome duplication (i.e. polyploidization) is common, particularly within plants [1]. This macromutation can impact both macroevolutionary processes of colonization, speciation and extinction [2], and microevolutionary processes of mutation, drift and natural selection [3].
Interspecific introgression mediates adaptation to whole genome duplication
Abstract Adaptive gene flow is a consequential phenomenon across all kingdoms. Although recognition is increasing, there is no study showing that bidirectional gene flow mediates adaptation at loci that manage core processes. We previously discovered concerted molecular changes among interacting members of the meiotic machinery controlling crossover number upon adaptation to whole-genome duplication (WGD) in Arabidopsis arenosa.
Interspecific introgression mediates adaptation to whole genome duplication
New Results Sarah Marburger, Patrick Monnahan, Paul J Seear, Simon H Martin, Jordan Koch, Pirita Paajanen, Magdalena Bohutínská, James D Higgins, Roswitha Schmickl, Levi Yant doi: https://doi.org/10.1101/636019 Abstract Adaptive gene flow is a consequential evolutionary phenomenon across all kingdoms of life. While recognition of widespread gene flow is growing, examples lack of bidirectional gene flow mediating adaptations at specific loci that cooperatively manage core cellular processes.
Pervasive population genomic consequences of genome duplication in Arabidopsis arenosa
Abstract Ploidy-variable species allow direct inference of the effects of chromosome copy number on fundamental evolutionary processes. While an abundance of theoretical work suggests polyploidy should leave distinct population genomic signatures, empirical data remains sparse. We sequenced ~300 individuals from 39 populations of Arabidopsis arenosa, a naturally diploid-autotetraploid species.

The Genomic Architecture of Flowering Time Varies Across Space and Time in Mimulus guttatus
The Genetics Society of America (GSA), founded in 1931, is the professional membership organization for scientific researchers and educators in the field of genetics. Our members work to advance knowledge in the basic mechanisms of inheritance, from the molecular to the population level. Online ISSN: 1943-2631

Epistasis Is a Major Determinant of the Additive Genetic Variance in Mimulus guttatus
Epistasis, the interactions between genetic loci, is an important determinant of phenotypes across a large number of taxa [1–8]. Yet for quantitative (complex) traits, the net effect of epistasis on the components of variation, specifically the additive genetic variance (V ) that determines the response to natural or artificial selection, remains polemical. This is evidenced by a renewed debate over the evolutionary relevance of epistasis as exemplified by Crow [9] and Hansen [10].
