Population structure and local adaptation in Tephrosia virginiana (Fabaceae).

Is is important to understand both adaptive and neutral genetic variation among plant populations. Neutral variation may represent evolutionary potential to respond to environmental change, and adaptive variation can inform restoration efforts. We sampled populations of the herbaceous plant Tephrosia virginiana (Fabaceae) located along wide climatic and edaphic gradients. We then used a population and landscape genomics approach to characterize population structure and potentially adaptive variation among populations. Populations were moderately differentiated across the study area at most loci. Stronger differentiation at several loci was correlated with environmental differences among collection sites suggesting that populations are locally adapted. Tephrosia virginiana may have substantial evolutionary potential to respond to environmental change, but local adaptation should be accounted for when sourcing seed for use in restoration.
