Unexpectedly high genetic variation in large unisexual clumps of the subdioecious plant Honckenya peploides
Honckenya peploides is a subdioecious dune plant that reproduces both sexually and by clonal growth. In northwest Spain this species was found to exhibit an extreme spatial segregation of the sexes, and our objective was to investigate genetic variation in unisexual clumps. Genetic variation was stu...
