Figure 2From: Molecular ecology and selection in the drought-related Asr gene polymorphisms in wild and cultivated common bean (Phaseolus vulgaris L.)Comparison of Asr genes to Phaseolus vulgaris general nucleotide diversity. π (E-2)statistic from the wild collection was computed. The background distribution was estimated by Cortés et al.[45]. Asr1 and Asr2 are indicated by arrows in the corresponding classes. Population structure and adaptive selection are associated with a high π values, but bottlenecks and directional selection is associated with low π value.Back to article page
