    Environmental Association Analyses Identify Candidates for Abiotic Stress Tolerance in Glycine soja, the Wild Progenitor of Cultivated Soybeans
    (2016-09-26) Anderson, J; Kono, Thomas J Y; Stupar, Robert M; Kantar, Michael B; Morrell, Peter L; kant0063@umn.edu; Kantar, Michael B
    Understanding the genetics basis of adaption is a fundamental goal of biological research. The present study explores an ex situ conservation collection, the USDA germplasm collection, genotyped at 32,416 SNPs, to identify population structure and test for associations with bioclimatic and biophysical variables in Glycine soja, the wild progenitor of Glycine max (soybean). Candidate loci were detected that putatively contribute to adaptation to abiotic stresses.

    Genotype and population data for "Isolation-by-environment and its consequences for range shifts with global change: landscape genomics of the invasive plant common tansy"
    (2024-04-29) Briscoe Runquist, Ryan; rbriscoe@umn.edu; Briscoe Runquist, Ryan
    Invasive species are a growing global economic and ecological problem. However, it is not well understood how environmental factors mediate invasive range expansion. In this study, we investigated the recent and rapid range expansion of common tansy across environmental gradients in Minnesota, U.S.A. We densely sampled individuals across the expanding range and performed reduced representation sequencing to generate a dataset of 3071 polymorphic loci for 176 individuals. We used non-spatial and spatially-explicit analyses to determine the relative influences of geographic distance and environmental variation on patterns of genomic variation. We found no evidence for isolation-by-distance (IBD) but strong evidence for isolation-by-environment (IBE).
