Floristic relationships between the Irano-Turanian and Mediterranean regions have been known from old. However, only a few biogeographical analyses based on molecular data have evaluated the history of steppe plants within the Mediterranean basin. Our study aims to contribute to a better understanding of the migratory and diversification processes by reconstructing the biogeography of Rhaponticoides (Cardueae), distributed in the Mediterranean and Irano-Turanian regions.

By this study, the palynomorphological traits of 49 taxa (53 plant samples) of the genus Muscari which has been the main research topic and also its relatives, Pseudomuscari, Hyacinthella and Bellevalia have been studied in details of both using light and scanning electron microscope. In the end of palynologic works, it was suggested the descriptive or symbolized main pollen types to make easier the separation or identification of the species of Muscari and its relative groups. According to this symbolization, the pollen types of species may be changeable as D-shaped, elliptical, triangular, and spindle shaped and all types could be seen in different members of the studied taxonomic groups in this paper.

Within the legume family, the taxonomic status of subtribe Glycyrrhizinae of tribe Galegeae and of the genus has been re-assessed. Based on genome skimming data, we conducted phylogenomic analyses of the inverted repeat-lacking clade within subfamily Papilionoideae. The results support the sister relationship between Glycyrrhizeae and .

The legume family (Fabaceae) exhibits a high level of species diversity and evolutionary success worldwide. Previous phylogenetic studies of the genus Hedysarum L. (Fabaceae: Hedysareae) showed that the nuclear and the plastid topologies might be incongruent, and the systematic position of the Hedysarum sect.

Mountains of Anatolia are one of the main Mediterranean biodiversity hotspots and their richness in endemic species amounts for 30% of the flora. Two main factors may account for this high diversity: the complex orography and its role as refugia during past glaciations. We have investigated seven narrow endemics of Centaurea subsection Phalolepis from Anatolia by means of microsatellites and ecological niche modelling (ENM), in order to analyse genetic polymorphisms and getting insights into their speciation.

The phytochemical investigation of the aerial parts of Centaurea deflexa led to the identification of 21 compounds, among which three phenolic acids, one sterol, ten flavonoids, one phenylpropanoid derivative, two lignans and four sesquiterpene lactones. One of the latter compounds was a new, rare active principle (1) having an uncommon 15-nor-guaianolide skeleton. The biological investigation was carried out through a bio-guided assay fractionation of C.

Three flavonoid glycosides were isolated and characterized, together with a further 13 substances belonging to various classes of compounds, in particular two phenolic acids, a coumarin, a sugar and nine flavonoids from the flowered aerial parts of Centaurea pseudoscabiosa subsp. pseudoscabiosa Boiss. et Buhse (Asteraceae).
