MOLECULAR PHYLOGENY AND SYSTEMATIC STATUS OF SOME TANACETUM L. (ASTERACEAE) TAXA FROM TURKEY
Gulden KOCAK
Abstract
Tanacetum is an important member of the Asteraceae family and considered the most problematic genus and the phylogenetic position of some taxa is of great interest because of the high morphologic diversity and taxonomical complexity. Among them T. heterotomum (endemic), T. cadmeum subsp. orientale (endemic), T. cappadocicum, and T. eginense have not been included in any molecular phylogenetic analysis yet. To determine the phylogenetic relationships and taxonomic status of Tanacetum L. taxa we analysed internal transcribed spacer (ITS) from nuclear ribosomal DNA (nrDNA) and trnL (UAA) intron, intergenic spacer between the trnL (UAA) 3’ exon and trnF (GAA) from chloroplast DNA (cpDNA). According to the phylogenetic trees basically two main clades are formed. While first clade includes T. eginense, T. cadmeum subsp. orientale and T. cappadocicum, the other clade includes T. heterotomum according to the data based upon the nrDNA. On the other hand, according to the cpDNA data, all four taxa were located in the same branch. Key words: Tanacetum, nrDNA, cpDNA, phylogeny
