Lamiaceae familyasında yer alan ve 150'den fazla tür içeren Sideritis cinsi dünyada özellikle Akdeniz havzasında yayılış göstermektedir ve ülkemizde 36'sı endemik olan 55 takson ile temsil edilmektedir. Bu yüksek endemizim oranı nedeni ile Türkiye Sideritis cinsinin iki gen merkezinden biri olarak kabul edilmektedir. Antalya Bölgesi'nde doğal yayılış gösteren 2 tek yıllık, 6 çok yıllık taksonun 12 lokasyondan örneklenerek incelendiği bu çalışmada, populasyonların uçucu yağ verimi % 0.0-0.3 aralığında bulunmuştur. En yüksek değer Sideritis congesta türünün Akseki lokasyonundan (% 0.3) elde edilirken bazı örneklerden uçucu yağ elde edilememiştir. 8 taksonda toplam 12 populasyona ait uçucu yağ örneğinin içerik analiz sonuçlarında toplam 55 bileşik tanımlanmıştır. Bu bileşiklerden β-pinen, α-pinen, limonen, linalol, karyofilen oksit, germakren-D ve δ-kadinen bileşikleri hem miktar hem de tanımlandığı örnek sayısı bakımından öne çıkan bileşikler olarak dikkat çekmiştir. Fenolik madde miktarlarının araştırılması amacıyla 14 takson ayrıca örneklenerek değerlendirilmiş, çalışmanın sonucunda populasyonlara ait toplam fenolik madde miktarlarının 27.5-68.9 mg GAE/g aralığında değiştiği bulunmuştur. En yüksek değer Sideritis stricta türüne ait örnekte, en düşük değer ise lokal endemik bir tür olan Sideritis albiflora türüne ait örnekte tespit edilmiştir.

In this research, clonal individual plants belong to Salvia fruticosa Mill. species, were collected from 15 different populations in the flora of Antalya. The clonal selection method was used in the breeding of this species, which is propagated clonally. Dry herbage yield was between 748.34 and 1135.15 kg/da for A clones, while it was between 748.34 and 1135.15 kg/da for B clones in terms of the population mean. The highest dry leaf yield was determined 534.36 and 605.867 kg/da for A and B clones respectively. Furthermore, 1.8-cineole, camphor and caryophyllene were determined as the main components of essential oils. The proportion of 1.8-cineole was determined between 34.51-73.49%. In this research, it was observed that there was a large variation between clonal lines, and some of them were determined as important in terms of morphological characteristics, yield and quality.

Samples were collected from early inflorescences, inflorescences and late inflorescences stages of 5 species grown in wild and cultivated conditions. Essential oils were obtained via steam distillation using Clevenger-type apparatus and they were analyzed with Gas Chromatography (GC). The highest average essential oil rate was obtained from inflorescences stage of wild O. majorana (8.2%) and followed by late inflorescences stage of wild O. majorana (6.1%) and inflorescences stage of cultivated O. onites (5.7%). Although cultivated O. majorana plants revealed lower essential oil rate than wild O. majorana, in the other species cultivated plants gave higher essential oil percentage. Eighteen compounds were identified in the essential oil of oregano species under studied conditions. The highest rate of carvacrol was found at the early inflorescences stage of cultivated O. majorana (53.90%) and followed by inflorescences stage of wild O. majorana (52.40%) and early inflorescences stage of wild O. majorana (50.10%). In general, rate of carvacrol in the wild and cultivated O. majorana, O. solymicum, O. onites and O. vulgare subsp. hirtum plants were appeared to be quite similar. However, percentage of carvacrol was found to be higher in the cultivated O. saccatum plants (average 40%) than wild O. saccatum plants (average 30%).

The study started with 200 genotypes in the first year, followed by the stem cuttings of 40 genotypes selected in the second year, in accordance with the obtained data, which were grown in rows (A clones), and the 10 genotypes (B clones) selected from the clones in the third year, which were grown in 3 replications according to a completely randomized block design. In accordance with the criteria for the evaluation of the results, 4 plants with superior characteristics were selected (C clones). Genotype 82 was regarded as a candidate with superior characteristics in terms of the amount of reb A content (7.95%, 7.77%, and 6.37%, respectively) and reb A/stv ratio (1.48, 1.20, and 1.48) over the 3 years. Genotype 109 was noteworthy for stv alone. Genotype 133 was considered as not only high in reb A (8.47%, 6.81%, and 6.40%, respectively), but also as an industrial material suitable for processing and production, as the agronomic properties were above average during the study. Genotype 196 was determined to be high in terms of the amount of reb A + stv (18.31%, 12.54%, and 13.58, respectively) and reb A (7.57%, 6.46%, and 6.2%, respectively). Therefore, these were selected as clonal variety candidates.

Bertoni is a perennial herbaceous plant and belongs to family of Asteraceae (Compositae). The contents of S. rebaudiana (Bert.) Bertoni consist mainly non-caloric stevioside and rebaudioside A sweeteners. Low seed germination is an important problem in stevia cultivation. Therefore in this study, the effects of light and temperature on germination performance of stevia seeds were studied. Stevia rebaudiana seeds were treated with two lights (light/darkness) and four different temperatures (15 oC, 20 oC, 25 oC, 30 oC). For each treatment, 50 seeds were counted and placed into petri dishes. Experiments were conducted as a randomized complete design method with three replicates. Germination was started within 6 to 10 days depending on the treatments. The highest seed germination rate (71%) was observed in darkness/25 oC temperature and followed by darkness/20 oC (68%) and light/25 oC (67%). On the other hand, the lowest seed germination rate (31%) was obtained from 15 oC in both light and dark conditions and followed by darkness/30 oC (43%) and light/30 oC (49%). The results showed that lower (15 oC) and higher (30 oC) temperatures significantly decreased the germination rates of stevia independently from the light treatments.

Carvacrol chemotype of Origanum dubium is used mainly for essential oil production due to its high essential oil content. In this study, chemical diversity of Origanum dubium was investigated in order to develop new cultivars with improved essential oil yield and carvacrol content using clone selection method under cultivated condition. Essential oils obtained by hydrodistillation of the aerial parts of Origanum dubium were analysed by GC-MS and 24 major components were identified. Among the selected genotypes, carvacrol was the major component and followed by p-cymene, γ–terpinene, myrcene and αthujene, respectively. The essential oil yields were varied between 5.0% to 14.0%; carvacrol rates were varied between 73.76% to 88.21%; and p-cymene rates were varied between 3.16% to 9.10%.

International Journal of Innovative Approaches in Agricultural Research, 2020

Almost all cells of any living organism contain DNA, a hereditary molecule that passes from gener... more Almost all cells of any living organism contain DNA, a hereditary molecule that passes from generation to generation during reproduction. The term "genome" generally refers to the total DNA sequences in an organism. The genome consists of DNA sequences called "gene", which plays a role in the basic biological processes involved in many phenotypic and genotypic characteristics, such as performing cellular functions, controlling numbers and species, regulating energy production, metabolism, and combating diseases. Gene editing is the process of pre-designing and modifying a particular DNA sequence in a targeted gene. The most widely used technique is CRISPR-Cas technology. For this purpose, the DNA helix is cut at a certain point, to form a double-strand break (DSB), and naturally existing cellular repair mechanisms repair the DSB. Modes of the repair mechanisms may affect the gene function. When DSB is formed, gene editing techniques can be applied to remove, insert, or replace a newly modified sequence using a synthetic donor template DNA. In developed and developing countries, CRISPR-Cas studies in addition to research and development studies are rapidly increasing. In addition to increasing population, changing weather conditions, declining farmland, increasing biotic and abiotic stresses are other important barriers to agricultural production, food, and feed supply. In this report, CRISPR-Cas applications are introduced in detail from the studies that carried out gene modifications in the fields of health, animals, plants, microorganisms, and food supply. Besides, these technologies and applications have been examined in terms of world biosafety legislation and the scientific risk assessment of the products developed using the CRISPR-Cas technique.
