The molecular phylogenetic position of Harpagocarpus (Polygonaceae) sheds new light on the infrageneric classification of Fagopyrum.

ABSTRACT: In the context of the molecular phylogeny of Polygonaceae, the phylogenetic positions of most genera and their relationships have been resolved. However, the monotypic genus Harpagocarpus has never been included in any published molecular phylogenetic studies. In the present study, we adopt a two-step approach to confirm the phylogenetic placement of Harpagocarpus using two datasets: (1) a concatenated dataset of three chloroplast DNA (cpDNA) regions (matK, rbcL and trnL-F) for Polygonaceae and (2) a combined cpDNA dataset of five sequences (accD, matK, psbA-trnH, rbcL and trnL-F) for Fagopyrum. Our analyses confirm the previous hypothesis based on morphological, anatomical and palynological investigations that
