Species may also colonize the same site on multiple occasions. Here, we examined the impact of local extinction and recolonization on the genetic structure of wild populations of lima beans (Phaseolus lunatus) in the Central valley of Costa Rica. We compared genetic diversity from the samples taken from the populations before and after extinction at 13 locations using microsatellite markers. ...

In spite of advancements in yacon morphological characterizations, the genetic diversity of the crop in molecular terms is still unknown. In the present study 30 cultivated accessions from the northern, center and southern regions of Peru were characterized by RAPDs. With 34 decameric primers 166 bands were generated, of which 30.7% were polymorphic. An index of similarity of 0.58 was chosen and 7 well differentiated subgroups or clusters were formed. The first cluster groups 22 accessions from the northern and southern regions with some from the center. The remaining clusters contain exclusively center region accessions. Duplicated individuals were not found and the greatest diversity was found in the center region of Peru. AMOVA reported 21.14% of variation explained by the among regions component and higher variability was concentrated among the accessions of each region (7...
