Population Genetic Analysis of the Threatened Plant Leavenworthia exigua var. laciniata (Brassicaceae) Reveals Virtually No Genetic Diversity and a Unique Mating System
Leavenworthia (Brassicaceae) has served as a model group for investigating the evolution of mating systems in plants, yet several Leavenworthia species remain understudied.One such taxon is Leavenworthia exigua var.laciniata, one of three varieties of L.exigua, a winter-annual plant endemic to the central United States.Because L.exigua var.laciniat
