Abstract

The genus Malcolmia W.T.Aiton is taxonomically problematic, and some of its species have recently been transferred to the genera Strigosella Boiss. and Zuvanda Dvorák. Three species of this genus are native to Turkey. The revision studies based on molecular data, which were collected in the past few years, display the phylogenetic relations and the systematic positions of the taxa more reliably and apparently. Thus taxonomic problems of species are resolved through DNA-based molecular analyses, which are not affected by environmental factors compared to phenotypic studies. In the present study, the amplifications of the DNA fragments were carried out using ISSR primers, and the phylogenetic relationship among the taxa was revealed through a dendrogram produced as the outcome of the NTSYSpc 2.1 software. The infrageneric and intergeneric phylogenetic relationships among Malcolmia and other related genera are determined. A very close relationship was determined between Malcolmia chia and M. flexuosa. Strigosella and Zuvanda species were determined to be phylogenetically different from these 2 species. The phylogenetic relationships among the Malcolmia, Strigosella, Zuvanda, Leptaleum DC., Neotorularia Hedge & J.Léonard, and Sisymbrium L. taxa were investigated. The phylogenetic separation of Malcolmia, Strigosella, Zuvanda Leptaleum, Neotorularia, and Sisymbrium genera and their specimens constituted separate clades on the dendrogram.
