The genus Sphagnum is one of the richest taxa among the Turkish bryophytes. Up to now, it has been represented by 27 taxa in six sections (Sphagnum, Acutifolia, Squarrosa, Subsecunda, Cuspidata, and Rigida). In this study, an identification key for the section Sphagnum was prepared, and the section was investigated using phylogenetic analyses, with a main focus on Turkish bryophytes. This study provides the first sequence data of the trnL intron region for five species of the section Sphagnum from Turkey (namely S. centrale, S. divinum, S. medium, S. palustre, and S.

The new lichen species Shackletonia backorii Halıcı, Güllü & Kahraman is described from James Ross Island, which is located in the North-East Antarctic Peninsula region. The new species is morphologically most similar to S. insignis (Søchting & Øvstedal) Søchting, Frödén & Arup, which was described from Livingstone Island (North-West Antarctic Peninsula region). These two species have a similar bluish grey to blackish thallus with a microfruticose and coralloid structure and red brown or almost black zeorine apothecia, but S. backorii has rhomboid ascospores and grows on soil whereas S.

A new species Pseudocercospora solanicola is discovered causing severe leaf spot disease on Solanum nigrum from Sonebhadra. Species is described and illustrated based on morphology, molecular sequence analysis and phylogeny of the large subunit (LSU) and internal transcribed spacer region of the nuclear ribosomal RNA (rRNA) gene. Morphologically, new species has similarity with allied species in Pseudocercospora but differs in having black circular, velvety leaf spot and size of stromata, conidia and conidiophores. A key to Pseudocercospora species on Solanum has been provided.

Abiotic stresses are serious environmental factors militating against the production of many crops around the world. The consequence of this, is the difficulty of meeting the demands of the increasing world population. Aside from other negative effects, reduction in photosynthesis is an important feature of abiotic stresses. Abiotic stresses limit photosynthesis in a number of ways. The reduction in ribulose 1, 5-bisphosphate carboxylase/oxygenase (Rubisco) content and activity is one of the paramount ways through which abiotic stresses affect photosynthesis.

Quinoa (Chenopodium quinoa Willd.) is a pseudo cereal crop, which is considered a new alternative crop due to its high nutritional value and tolerance to environmental stresses. Its seeds are rich in proteins and amino acids (e.g., lysine, threonine, and methionine) that are deficient in other pseudo-cereal crops. It also contains essential fatty acids, such as linoleic, and alpha-linolenic acids, and high quantities of vitamins, e.g., riboflavin (B2), and tocopherol (vitamin E), and inorganic nutrients.

According to the current taxonomic delimitation, the Mediterranean genus Iberis comprises about 30 species. Among them, the taxonomy and species delimitation of Iberis simplex and its morphologically close relatives (I. attica, I. carica, I. gypsicola, I. halophila, and I. spruneri), described here as the I. simplex species complex, are controversial and several different names are used for the members of this complex.

Cyclic nucleotide-gated channels (CNGCs) are ligand-gated calcium signaling channels, play vital biological functions. Nonetheless, the CNGC gene families have not been well studied in Brassicaceae which includes commercially important and evolutionary model crops. Here, using in silico approaches, we recognized 414 CNGC genes in sixteen sequenced genomes of Brassicaceae species, which represent 10 genera of 8 tribes, ranging between 10‒51 genes.

Ampelopsis grossedentata is an important national medicine in China. It is mainly used commonly by the Yao, Miao, Dong, and other ethnic minorities of China. The current literature, however, contains no study on the molecular genetics and taxonomy of A. grossedentata, which had led to potential problems in the conservation and utilization of this resource. Therefore, the present study was aimed to use simple sequence repeat (SSR) markers for assessing the levels and the distribution of genetic diversity in a sample set of 225 individuals from nine populations of A. grossedentata in China.

Poplar cultivation has economic, social, ecological, and environmental importance in Turkey. Even though, Populus × canadensis hybrids play an important role for the commercial poplar cultivation with good growth performance and adaptability, hybrid clones introduced the different region of Turkey have started to replace the native stands of Populus nigra gradually. To continue sustainable cultivation of poplar and to conserve the native stands of P.

Lamium is a taxonomically convoluted genus of about 34 species. Within Lamium, the L. garganicum species complex is particularly challenging. Here, based on morphological and molecular studies, Lamium cappadocicum Celep & Karaer sp. nova (Lamiaceae) is separated from L. garganicum and L. bilgilii and described as a new species, and L. garganicum subsp. rectum (= L. garganicum subsp. pulchrum) is resurrected. The new species is only known from the Hasan Mountain (Aksaray) in Central Anatolia, Turkey.

Stachys species show high morphological diversity and their main diagnostic characteristics are calyx and corolla length, ratio of tooth to calyx, and verticillaster arrangement. This manuscript describes and provides detailed morphological, micromorphological and molecular information about a new species, Stachys istanbulensis Ö. Güner, and its close relatives. The new species resembles S. recta complex, but is distinguished by its procumbent flowering stems, shorter calyx and teeth, congested verticillasters, creamy yellow corolla and oblong-obovoid nutlets.

Marrubium zeydanlii (Lamiaceae) is described as a new species from Turkey. It is similar to M. depauperatum and M. sivasense; however, it is distinguished from M. depauperatum by having lanate hairs on the stem, oblanceolate dentate leaves, 4–6-flowered verticillasters. It is also distinguished from M. sivasense by having lanate hairs on the stem, oblanceolate leaves, and shorter petals. The pollen grains are radially symmetrical and isopolar, the shape is oblate-spheroidal with the polar axes 16.7–20 µm and the equatorial axes 17.6–19.3 µm.

This study was aimed to evaluate the physicochemical properties and chemical profile of seeds oil obtained from new seven sunflower (Helianthus annuus L.) lines as well as their antioxidant and enzyme inhibition activity. The seeds powder was extracted by maceration in n-hexane. The oil content of the seven lines was ranged from 20.04% to 36.65% and was either yellow or pale yellow in color. No significant variations were observed on the refractive index (1.46 unit) of the oil.
