    Genetic diversity of wild papaya

    In order to determine whether genetic architecture stems from pre-Pleistocene events or refugia, Chávez-Pesqueira and Núñez-Farfán assess genetic diversity and population dynamics of 19 populations of wild papaya (Carica papaya) from northern Mesoamerica. Phylogenetic analysis using cpDNA markers indicates a lack of a phylogeographic structure, and nuclear markers reveal a recent population structure. This suggests […] More
