A new species of Cousinia (sect. Cousinia, Asteraceae) from the Ağrı Mountain (eastern Turkey): evidence from morphology, karyology and anatomy

Phytotaxa (2019)

Osman Tuğay Deniz Ulukuş Kuddisi Ertuğrul Tuna Uysal Hakkı Demirelma

Cousinia agridaghensis (sect. Cousinia) from Ağrı province, eastern Turkey, is described as new to science. The new species is morphologically closely related to C. urumiensis, C. fedorovii and C. armena but differs in capitula shape, synflorescence shape, stem height, shape of segments of basal and uppermost cauline leaves. In addition, the new species is compared with C. urumiensis, which is distributed in Turkey, in terms of chromosome number and anatomical features. The basic chromosome number is determined x = 12 in C. agridaghensis and x = 13 in C. urumiensis. The differences in leaf midrib shape and number of vascular bundles in C. agridaghensis and C. urumiensis are observed. The achene coat and pollen grain surface of C. agridaghensis and C. urumiensis are studied with SEM photographs. Furthermore, a detailed description, distribution map, conservation status and ecology of the new species are given.

Karyological studies of four endemicCentaureaL. species

Caryologia (2015)

Tuna Uysal Meryem Bozkurt Ela Nur Şi̇mşek Sezer Kuddisi Ertuğrul Osman Tuğay

In this paper, four endemic Centaurea species were investigated in terms of their chromosome numbers and karyomorphology. The chromosomal counts confirmed the results of previous reports, that the genus Centaurea has different basic chromosome numbers. Centaurea yaltirikii and Centaurea demirizii are diploid taxa. Centaurea yaltirikii has 2n = 18 chromosomes, and therefore has a basic chromosome number of nine, which is common in the genus Centaurea. A local endemic species, Centaurea demirizii has 2n = 16 chromosomes and a different basic chromosome number of x = 8, and this basic number is relatively rare for Centaurea. Centaurea leptophylla and Centaurea saligna are tetraploid with 2n = 36 chromosomes. We found predominance of chromosomes being metacentric and submetacentric. The results increase our karyological knowledge of these species. Moreover, this paper gives short taxonomic and morphologic notes to complement the information provided by Flora of Turkey with regards to the studied species.

COMPARATIVE MORPHOLOGICAL AND TAXONOMICAL STUDIES ON SOME PSEPHELLUS TAXA (ASTERACEAE) IN TURKEY

Phytotaxa (2020)

Meryem Bozkurt Tuna Uysal Kuddisi Ertuğrul

Three close endemic species of Psephellus section Odontolophoidei were compared with regard to their micro- and macromorphological characters to explore their taxonomic circumscription and relationships. In the scope of detailed morphologic studies, the deficiences found in the species descriptions in Flora of Turkey were corrected. Detailed descriptions and a useful key were prepared in light of newly obtained morphologic data. During the numerical studies, 96 qualitative and quantitative characters were converted into numerical values. The obtained data and their matrices were used in the phenetic analyses. Following this process, a phenogram was created based on the similarity index, and the spatial distributions of the taxa were assessed using nMDS (non-metric multidimensional scaling). The findings indicated that the microstructural features of the achenes observed using scanning electron and light microscopy are very important for the classification of Psephellus, and they can be used as effective taxonomical tools to determine the relationships of closely related taxa. As a result of these studies, Psephellus aucherianus could be characterized as the most variable and relatively common species when compared to the remaining relatives within the section. Psephellus yusufeliensis was found near Ps. aucherianus and it had a fairly local and narrow distribution. In light of the micromorphological data and phenetic analyses, Psephellus sintenisii is accepted at species rank as a new combination for Flora of Turkey. Morphological descriptions and nomenclatural types are indicated for all accepted taxa, including designation of a lectotype for Ps. sintenisii. Data on phenology, ecology, and distribution are also reported.

Centaurea Revisited: A Molecular Survey of the Jacea Group

Annals of Botany (2006)

Núria Garcia‐Jacas Tuna Uysal Kostyantyn Romashchenko Víctor N. Suárez‐Santiago Kuddisi Ertuğrul

The genus Centaurea has traditionally been considered to be a complicated taxon. No attempt at phylogenetic reconstruction has been made since recent revisions in circumscription, and previous reconstructions did not include a good representation of species. A new molecular survey is thus needed.Phylogenetic analyses were conducted using sequences of the internal transcribed spacers (ITS) 1 and 2 and the 5.8S gene. Parsimony and Bayesian approaches were used.A close correlation between geography and the phylogenetic tree based on ITS sequences was found in all the analyses, with three main groups being resolved: (1) comprising the most widely distributed circum-Mediterranean/Eurosiberian sections; (2) the western Mediterranean sections; and (3) the eastern Mediterranean and Irano-Turanian sections. The results show that the sectional classification in current use needs major revision, with many old sections being merged into larger ones. A large polytomy in the eastern Mediterranean clade suggests a rapid and recent speciation in this group. Some inconsistencies between morphology and molecular phylogeny may indicate that hybridization has played a major role in the evolution of the genus.Phylogenetic analysis of ITS has been useful in identifying the major lineages in the group, and unraveling many inconsistencies in the sectional classification. However, most recent groups in the eastern Mediterranean clade are not resolved and reticulation in the western Mediterranean group of sections makes phylogenetic relationships within these two groups somewhat obscure.
