Data from: Role of seed germination in adaptation and reproductive isolation in Arabidopsis lyrata
Seed germination is an important developmental and life history stage. Yet, the evolutionary impact of germination has mainly been studied in the context of dormancy, or for its role in reproductive isolation between species. Here, we aim to examine multiple consequences of genetic divergence on germination traits between two Arabidopsis lyrata subspecies: ssp. petraea (Eurasia) and ssp. lyrata (North-America). Post-dormancy germination time, a potentially adaptive trait, showed differentiation between the populations, and quantitative trait loci (QTL) mapping revealed that the trait variation is mainly controlled by two antagonistic loci. These QTL areas contain several candidate genes with known function in post-dormancy germination in A. thaliana. The sequence variation of three genes was consistent with differential selection, and they also included fixed nonsynonymous substitutions with potential to account for the phenotypic differentiation. We further show that the divergence between the subspecies has led to a slight but significant reduction in hybrid germination proportions, indicating incipient reproductive isolation. Comparison of reciprocal F1 and F2 progenies suggest that Bateson-Dobzhansky-Muller-incompatibilities likely act through uniparentally inherited factors. Examination of genome-wide transmission ratio distortion further revealed that cytonuclear interactions cause substantial pregermination inviability in the hybrids. These results confirm that seed germination has adaptive potential beyond the dormancy stage and that hybrid seed inviability can be one of the first reproductive barriers to arise during divergence.
Dataset for: Understanding the biogeographic patterns of closely-related species of Paspalum (Poaceae) using distribution modelling and seed germination traits
<p>This dataset supports the reported results of the namesake article submitted to Plants (MDPI). It contains the results from both germination experiments assayed and the data used for ANOVA, PCA and PLSR analyses. Also, it includes the data used to optimize favourability functions to build SDMs and the coordinates of each specimen considered in this research.</p>
