Adaptation During Range Expansion to High-latitude Environments in Populus balsamifera

Genome-wide Diversity and Association Mapping in Medicago truncatula

These projects both make use of high-throughput DNA sequencing technologies to evaluate genome-scale nucleotide diversity in model plant species, Populus balsamifera (balsam poplar) and Medicago truncatula (barrel medic). The data will be analyzed using computationally intensive coalescent-based analyses. There are three basic goals: describing how nucleotide diversity is structured across the genome, identify the evolutionary forces that shape this diversity, and identify genes that underlie phenotypic variation in ecologically important traits.
