Seed Morphology And Surface Microstructure Of Some Euphorbia (Euphorbiaceae) Taxa Distributed In Turkey-In-Europe, Levent Can, Orhan Küçüker
Turkish Journal of Botany
The taxa of the genus Euphorbia L. Have seeds that mature in schizocarp fruits, called cocci, with three or more cells, each of which explosively splits open into separate parts at maturity. The Euphorbia seeds have taxonomically useful characters. We studied 13 taxa of the genus Euphorbia distributed in Turkey-in-Europe, with a focus on the seed characters; for morphological observations we used a stereomicroscope, and for surface microstructure we used a scanning electron microscope (SEM). The morphological observations showed that the seed characters of shape, size, color, surface features, and the features of the caruncle are uniquely different. SEM observations …

Variability Of Plant Species Diversity During The Natural Restoration Of The Subalpine Birch Forest In The Central Great Caucasus, Natalia Togonidze, Maia Akhalkatsi
Turkish Journal of Botany
The northern slopes of the Central Great Caucasus of Georgia were covered by birch (Betula litwinowii) forests in the past, but forest degradation resulted in subalpine secondary meadows. Over the past 20 years birch forest natural reforestation processes have taken place. The aim of this study was to determine the changes in plant species diversity during reforestation. Different habitat types were selected to trace the development of birch forests from subalpine meadows. Species richness was determined in 100 research plots (25 m2 each) of different habitat types. Pioneer succession was distinguished by the highest level of species richness due to …

Phylogeny And Systematics Of The Western Mediterranean Vella Pseudocytisus-V. Aspera Complex (Brassicaceae), Violeta I. Simón-Porcar, Ernesto Perez-Collazos, Pilar Catalan
Turkish Journal of Botany
The evolution and taxonomy of the core members of subtribe Vellinae (Brassicaceae), comprising Vella aspera, V. Bourgeana, and V. Pseudocytisus, is still poorly known. We reconstructed the evolutionary relationships among these taxa and other Vellinae and close Brassicaceae using nuclear ITS and plastid trnTF phylogenies, and analyzed the phenotypic traits that differentiate the infraspecific ranks of V. Pseudocytisus. Our phylogenetic analyses show: i) an early divergence of Succowia within the Brassiceae-Sisymbrieae sensu lato clade; ii) the nested positions of Vella bourgeana (syn. Euzomodendron bourgaeanum) and V. Aspera (syn. Boleum asperum) within the Vella clade; and iii) the split of 5 …

Mechanisms Of Tolerance Differences In Cucumber Seedlings Grafted On Rootstocks With Different Tolerance To Low Temperature And Weak Light Stresses, Yan Li, Xuemei Tian, Min Wei, Qinghua Shi, Fengjuan Yang, Xiufeng Wang
Turkish Journal of Botany
Stresses of low temperature and weak light are major environmental limiters for horticultural production in greenhouses in northern China during winter and early spring. Grafting is regarded as a promising approach to enhance cucumber tolerance to these environmental stresses. However, it is still unclear why cucumber plants grafted on different rootstocks usually exhibit different tolerance. The responses of cucumber (Cucumis sativus L. Cv. 'Xintaimici') seedlings that were grafted on three rootstock cultivars ('Kilameki', 'Tielizhen', and 'Figleaf gourd') to low temperature (5 °C) and weak light (100 µmol m-2 s-1) were investigated in this study. The results showed that, compared to …

Genetic Diversity And Relationships Within And Among Onobrychis Species Using Molecular Markers, Mohammad Zarrabian, Mohammad Mahdi Majidi
Turkish Journal of Botany
Little is known about the taxonomic relationships of the genus Onobrychis (Fabaceae). To study inter- and intraspecific variations and the relationships among the species, 102 accessions (33 species) of the genus Onobrychis were evaluated using 22 inter-simple sequence repeat (ISSR) markers. Almost all the species belonging to the section Onobrychis clustered together. A similar pattern was found with the species belonging to the section Hymenobrychis, while those of the section Lophobrychis did not cluster together. The results indicate that the section Lophobrychis has a comparatively derived organization that can be attributed to the differences in their taxonomic delimitation. Geographical pattern …

Relationships And Generic Delimitation Of Eurasian Genera Of The Subtribe Asterinae (Astereae, Asteraceae) Using Molecular Phylogeny Of Its, Elena Korolyuk, Alexey Makunin, Tatiana Matveeva
Turkish Journal of Botany
The subtribe Asterinae (Astereae, Asteraceae) includes highly variable, often polyploid species. Recent findings based on molecular methods led to revision of its volume. However, most of these studies lacked species from Eurasia, where a lot of previous taxonomic treatments of the subtribe exist. In this study we used molecular phylogenetics methods with internal transcribed spacer (ITS) as a marker to resolve evolutionary relations between representatives of the subtribe Asterinae from Siberia, Kazakhstan, and the European part of Russia. Our reconstruction revealed that a clade including all Asterinae species is paraphyletic. Inside this clade, there are species with unresolved basal positions, …

Metabolic And Molecular-Genetic Regulation Of Proline Signaling And Itscross-Talk With Major Effectors Mediates Abiotic Stress Tolerance In Plants, Aryadeep Roychoudhury, Aditya Banerjee, Vikramjit Lahiri
Turkish Journal of Botany
Proline (Pro) accumulation is a common response of several plant species to combat abiotic stresses. Under stress conditions, Pro acts as an excellent compatible solute in the plant system, participating in the alleviation of stress sensitivity. Though the metabolic pathways associated with Pro are well studied, parts of its regulatory cascades are still not properly known. It has also been conjectured that epigenetic modifications regulate Pro metabolism during abiotic stress. Apart from Pro, the plant abiotic stress responses are essentially mediated by multiple effectors. Hence, proper analysis of the cross-talks of Pro with the other components of the abiotic stress …

Estimating Genetic Diversity Among Selected Cotton Genotypes And The Identificationof Dna Markers Associated With Resistance To Cotton Leaf Curl Disease, Ammad Abbas, Muhammad Atif Iqbal, Mehboob-Ur Rahman, Andrew H. Paterson
Turkish Journal of Botany
To the extent of our knowledge, applications of DNA markers in marker-assisted breeding of cotton are handicapped due to low genetic diversity in cotton germplasm. Cotton leaf curl disease, a disease of viral origin, has substantially depressed cotton production in Pakistan, and this disease is also an emerging threat to the neighboring cotton-growing countries like China and India. The present study was designed to identify DNA markers, predominately simple sequence repeats (SSRs), associated with tolerance and/or resistance to the disease. Based upon 2 years of disease-screening field experiments, a total of 10 cotton genotypes (five highly tolerant, four highly susceptible, …

Evaluation Of Metabolite Extraction Protocols And Determination Ofphysiological Response To Drought Stress Via Reporter Metabolites In Model Plant Brachypodium Distachyon, Özge Tatli, İlkem Emrah Ni̇kerel, Bahar Soğutmaz Özdemi̇r
Turkish Journal of Botany
Metabolomics aims to systematically gather (quantitative) information on metabolites in the cell and is commonly viewed as the "missing link" between genomics, transcriptomics, and physiology. Typical metabolomics platforms consist of two main steps, the quenching and extraction of metabolites from plant material and the (un)targeted quantification of the extracted metabolites. Brachypodium distachyon, a native grass species of the Mediterranean region, is an attractive model plant to study temperate crops. In recent years, despite an increasing interest in genomic and transcriptomic studies, metabolomics studies for B. Distachyon are still in their infancy. Drought, an abiotic stress factor, causes severe loss in …

Turkish Journal of Botany
In the present study, to determine the effects of β-estradiol on the ability of plants to tolerate lead toxicity, β-estradiol (10 μM) and lead (1.75 mM), singly or in combination, were exogenously applied to wheat seeds. Although lead resulted in a marked increase in the activities of antioxidant enzymes, including superoxide dismutase, guaiacol peroxidase, ascorbate peroxidase, and glutathione reductase (but not catalase), as well as an increase in the level of antioxidant compounds such as ascorbic acid and glutathione, this was insufficient to ameliorate the lead-induced oxidative injury or the superoxide anion, hydrogen peroxide, and malondialdehyde levels. However, β-estradiol was …

Morphology And Genetic Affinities Of A Novel Chattonella Isolate (Raphidophyceae) Isolated From Iran’S South Coast (Oman Sea), Gilan Attaran Fariman, Christopher John Stanley Bolch
Turkish Journal of Botany
The morphology and genetic affinity of a novel raphidophyte belonging to the genus Chattonella Biecheler is described for the first time from the Oman Sea along the south-east coast of Iran. While morphologically very similar to Chattonella subsalsa Biecheler, the Iranian isolates contain a distinct red eyespot. A comparison of LSU-rDNA and rDNA-ITS show that the Iranian isolate is genetically distinct from other Chattonella subsalsa strains isolated from across a wide global range and indicates that the Iranian isolates represent a distinct species related to Chattonella subsalsa.
