- MakaleAçık Erişim2024Scopus SJRQ3Heracleum munzurense (Apiaceae), a new species from East Anatolia, Turkey and taxonomic position of Tetrataenium lasiopetalum
Duran, Ahmet; Lyskov, Dmitry; Samigullin, Tahir; Paksoy, Mehmet Yavuz
A new species, Heracleum munzurense (Apiaceae), is described from East Anatolia, Turkey. It grows in damp places formation of the Munzur Mountains in the district of Pülümür (Tunceli Province). The taxonomic affinities of the new species were determined by analyzing morphological data and through a molecular phylogenetic study of nrITS/ETS. The new species is morphologically and genetically related to H. apiifolium and H. pastinaca, but differs mainly in stems, leaves, pedicels, rays and petals pubescence, petals size, fruit hairs, and size features. The anatomical structure of the fruit is given. The diagnostic morphological characters of the new species are discussed. In this study, the geographical distribution of the new species and the related taxa H. apiifolium, H. lasiopetalum, and H. pastinaca is mapped. In addition, the habitat, ecology, phenology, and conservation status of the new species are also provided. Tetrataenium lasiopetalum is also closely related to this group of species. Common morphological features and results of molecular phylogenetic study suggest to transfer this species back to the genus Heracleum.

Lyskov, Dmitry; Duran, Ahmet; Paksoy, Mehmet Yavuz; Samigullin, Tahir
A new species, Prangos munzurensis (Apiaceae), is described and illustrated from Tunceli Province, Eastern Turkey. The new species is related to Prangos heyniae, P. abieticola, and P. denticulata and differs from them in the number of rays, length of bracts, indumentum of petals, ultimate segments of leaves, stylopodium features, fruit morphology and anatomy, and distributional range. It also differs from P. ferulacea in presence of furrows between blocks of inner mesocarp, number of umbel rays, and puberulous petals. A comprehensive description of the morphological and carpo-anatomical features, photographs, and data on the geographical distribution, habitat and ecology, and conservation status are also provided. In addition, P. munzurensis is recognized as a separate species by molecular analysis of nrITS/ETS.
AtıfScopus2OpenAlex2İncele - MakaleAçık Erişim2021Phylogenetic analysis of the genus conringia heist. Ex fabr. (brassicaceae) in turkey based on nuclear (nrits) and chloroplast ((trnl-f)) dna sequences
Sevindik, Emre; Aydogan, Melike; Paksoy, Mehmet Y.
In this study, phylogenetic analysis of Turkish Conringia (Brassicaceae) species was conducted based on nuclear ribosomal DNA (nrITS) and chloroplast DNA (trnL-F) sequences. In addition, the relationships between the sequences of some Brassicaceae family species retrieved from NCBI, and Conringia species were documented. All of the plant specimens were collected at their flowering and vegetation periods from different regions of Turkey, and brought to the laboratory. Total genomic DNA was extracted using the GeneMark kit. In PCR analyses, ITS4 and ITS5A primers were used for the amplification of the nrITS region, while the trnLe and trnLf primers were used for the cpDNA trnL-F region. The DNA sequences obtained were then edited using BioEdit and FinchTV, and analyzed using MEGA 6.0 software. Neighbor joining (NJ) and bootstrap trees were constructed in order to identify the relationships among Conringia taxa. The nrITS sequences ranged between 573 and 672 nucleotides, while the trnL-F sequences ranged between 346 and 764 nucleotides. The divergence values of nrITS sequences differed between 0.177 and 0.00 and divergence values of trnL-F sequences differed between 0.902 and 0.00. NJ tree generated using nrITS and trnL-F sequences consisted of two clades. In trees generated with both the nrITS and trnL-F sequences, C. orientalis, C. grandiflora and C. austriaca appeared within the same group. In addition, according to the phylogenetic analysis results obtained with other Brassicaceae species, it is revealed that the Conringia genus is polyphyletic.
