Mating patterns in Daphne jezoensis: An application of NM+.

Mating patterns are vitally important in the evolution of plant populations.  Gene flow within and among populations influence many characteristics including genetic diversity, effective population size, and inbreeding depression rates.  The influence of gene flow is of particular importance when considering mating system evolution.  Daphne jezoensis is a gynodioecious shrub believed to be evolving towards dioecy.  Selfing rate, dispersal distance, and offspring success rate are examples of evolutionary factors that are influenced by mating system patterns, and impact the direction and rate of change within a population.  NM+ is a software program designed to use these factors to predict parentage of offspring and infer patterns of pollen-mediated gene dispersal.  Here, we apply NM+ to a population of D. jezoensis in Northern Japan to explore gene dispersal and the effects of this dispersal on mating system evolution.
