The evolution of common bean (Phaseolus vulgaris) using pooled DNA re-sequencing data

TL;DRAbstract

Domestication of plants has is correlated with the transition from hunter-gatherer societies to agricultural-based societies. The understanding of genes involved in the domestication process can reveal aspects of plant evolution and as well as beneficiate crop improvement. With the new era of DNA sequencing technologies, the data gathering can be done much ore quickly and efficiently to better understand plant genome evolution. Using a pooled DNA re-sequencing approach, more individual can be sequenced and genetic variation and rare alleles can be determined. Here, we evaluated re-sequencing data derived from nine subpopulation of common bean (Phaseolus vulgaris) corresponding to wild undomesticated relatives and domesticated landraces. Common bean is one of the most important legumes worldwide and was domesticated independently both in Central America/Mexico and South America. These two independent domestication events resulted in two distinct genetic pools (Andean and Mesoamerican).
