Phylogenetic analysis of Crocus (Iridaceae) and inference of the phylogeography of Crocus biflorus in Anatolia

番红花属Crocus L.（鸢尾科）由约90种组成，在巴尔干半岛和土耳其的物种数量最多。许多番红花属植物被用作观赏植物，C。大蒜是大蒜素的来源。番红花分为两个亚属，番红花和番红花，后者有两个组和15个系。番红花属中最大的类群是双头番红花属，约有13种，其中C. biflorus进一步细分为c. 15个亚种这些亚种主要分布在安纳托利亚的山区，通常仅限于小山脉甚至单一的山峰。生长在低海拔的森林有效地隔离了空中岛屿上的种群。在这个项目中，我们希望使用核和叶绿体DNA序列的嵌套方法分析整个属内的系统发育关系。特别是C. biflorus物种复合体将用系统发育和地理分布的方法进行分析，从而得出更新世气候变化期间物种历史和物种形成过程的结论。一般来说，番红花属植物可以作为安纳托利亚高山植被的代表。

The genus Crocus L. (Iridaceae) consists of about 90 species, occurring with the highest species numbers in the Balkans and Turkey. Many Crocus species are used as ornamental plants, and C. sativus is the source of saffron. Crocus is divided in two subgenera, Crociris and Crocus, the latter with two sections and 15 series. The largest series within Crocus are the Biflori taxa with about 13 species, of which C. biflorus is further subdivided into c. 15 subspecies. These subspecies occur mainly in the mountains of Anatolia and are often restricted to small mountain ranges or even single summits. Forests growing at lower elevations effectively isolate the populations on sky islands. With this project we want to analyze phylogenetic relationships within the entire genus with a nested approach using nuclear and chloroplast DNA sequences. Particularly the unclear species delimitations in the C. biflorus species complex will be analyzed with phylogenetic and phylogeographic methods, which allow drawing conclusions on species history during Pleistocene climate changes and processes occurring during speciation. Generally, Crocus species can function as representatives for the high mountain vegetation of Anatolia.
