ИСТИНА

The small tribe of Coriandreae W.D.J.Koch, having been recognized in the first classification of the Umbelliferae genera (Koch, 1824) remain unsufficiently investigated from the viewpoint of molecular phylogenetics. All eight genera of the Umbelliferae, attributed to the tribe of Coriandreae besides 42 additional sequences from GenBank of the species, presumable relatives of Coriandreae, were included too. Phylogenetic analysis of two nuclear (ITS, ETS) and one chloroplast (psbA-trnH) markers were performed to check a monophyly of the tribe. Phylogenetic trees were obtained for each marker separately, as well as for combined data matrix set using two methods of inference – MrBayes (BS) and maximum parsimany (MP). The Coriandreae genera fall in molecular trees in three different clades. These clades are not neighbours in trees, being separated by other clades, composed by other Apioideae taxa, mainly belonging to the huge tribe of Apieae. The studies clearly showed that there are three separate groups within Coriandreae, differing in their sequences of ITS and ETS of nuclear ribosomic DNA. Only Bifora appeared to be closely related to Coriandrum, whereas Fuernrohria falls in Apieae, and five remaining genera, endemic or subendemic to Middle Asia, form compact separate clade, which could be marked as a new tribe Schrenkieae, as it has some morphological differences from all remaining taxa of former Coriandreae s. The monophyly of one more tribe of the Umbelliferae became a thing of the past. We forced to treat Coriandreae in considerably narrower volume (two genera - Coriandrum и Bifora). This paradoxically returns us to the sources, to W.Koch’s first Umbelliferae classification.
