| Popis | Sequence data from nuclear (ITS) and chloroplast (trnL-F) regions for 89 accessions representing 56 out of 64 species from all five genera of the tribe Chorisporeae (plus Dontostemon tibeticus) have been studied to test the monophyly of the tribe and its component genera, clarify its boundaries, and elucidate its phylogenetic position in the family. Both data sets showed strong support for the monophyly of the Chorisporeae as currently delimited, though the position of its tentative member D. tibeticus was not resolved by ITS. Parrya and Pseudoclausia are poly- and paraphyletic with regard to each other, and Chorispora is either polyphyletic or at least paraphyletic (comprising Diptychocarpus) within a weakly supported monophyletic clade. We also obtained support for splitting Chorispora into two geographically defined groups, one of which is closer to Diptychocarpus. Both data sets revealed a close relationship of the Chorisporeae to Dontostemoneae, while ITS also indicated affinity to Hesperideae. |
