Özet
Origanum L. (Lamiaceae) comprises perennial herbs with medicinal and culinary uses and is largely confined to the Mediterranean Basin. Despite the economic importance of this genus, phylogenetic relationships and species boundaries are unclear and insufficiently studied. We sequenced the nuclear internal transcribed spacer (ITS) DNA region from 40 Origanum taxa and 32 outgroup specimens. Using this data, we tested sectional and species relationships in Origanum together with molecular dating, biogeographical and character evolution analysis. Molecular results shown that Origanum is a monophyletic genus, however sections of the genus proposed by morphological data are not monophyletic. Thymus L. is sister to Origanum (PP = 1), and the two genera diverged 5.14-6.5 mya. Origanum diversified during the Pliocene, 3.05-5.33 mya. Biogeographic analysis shows and Eastern Mediterranean region is the center of diversity and origin of the genus. In addition, we reconstructed the evolution of four morphological characters which have been used as diagnostic characters in previous infrageneric classifications of Origanum. © 2022 Nova Science Publishers, Inc.
