Molecular Phylogenetics of Some Orchis Species (Orchidaceae) Native To Turkey Using Nuclear and Chloroplast Dna Sequences

Abstract

Phylogenetic relationships among nine Turkish Orchis species were inferred from variation in the internal transcribed spacer and maturase Kinase regions. Foreign sequences were also retrieved from NCBI to increase interspecific sampling. The topology of ITS tree was broadly congruent to that of matK tree. The trees showed two major clades; the first one included species from Orchis and Neotinea subgenera and the second included species of Anacamptis subgenus. Phylogenetic separation of some species found in Neotinea and Anacamptis subgenera were previously reported, and the current study also indicated that moving these species into Neotinea and Anacamptis genera could be reasonable.
