Effects of mode of reproduction on genetic polymorphism and divergence in wild yams (Dioscoreaceae: ).

Evolutionary transitions from sexual to asexual reproduction should have significant influences on genetic divergence and polymorphism at the genome level. Plant lineages with diverse reproductive systems provide opportunities to investigate this question using comparative approaches and studies of molecular evolution. We investigated evidence for differences among the transcriptomes of 19 species (wild yams) with diverse reproductive systems.
