Physiological and biochemical screeing of different Turkish Lentil (Lens culinaris M.) cultivars under drought stress condition

Gökçay, Derya
Legumes being the most important crops worldwide are limited in terms of adaptability and productivity mainly by the abiotic stresses. In this study, the aim was to understand tolerance mechanisms of lentil cultivars under drought stress by physiological and biochemical analyses. This study was carried out with six Turkish Lentil cultivars (Seyran, Kafkas, Malazgirt, Çağıl, Çiftçi, Özbek) subjected to drought stresses (10% and 15% PEG) and their physiological and biochemical properties were examined to select drought-tolerant and drought-sensitive cultivars. Drought stress was applied for 5 days to 7 days-grown lentil plants. 12-days old, stressed and control plant shoots and roots were analyzed in terms of physiological and biochemical parameters (length, fresh weight, ion leakage, proline, MDA and H₂O₂ content). According to these analyses, Seyran and Çağıl cultivars were selected as drought-tolerant and drought-sensitive, respectively. The responses of tolerant and sensitive cultivars were compared via analyzes of antioxidative enzyme activities (APX, CAT, GR and SOD) and protein profiles.


Physiological and biochemical screening of different Turkish lentil cultivars under salt stress conditions
Köse, Fatma Selin; Çalık, Pınar; Özdamar, Tunçer H.; Department of Biotechnology (2012)
Salinity is the 2nd major limiting abiotic factor on plant growth. As a result of this, soil salinity greatly reduce the yield of the crop production by dual action on plants which are ionic toxicity and water deficit. Therefore, improvement of stress tolerance is greatly concerned. This study was performed to screen and select a salt-resistant and a salt-sensitive cultivar among 6 Turkish lentil cultivars (Lens culinaris M.) which are Çağıl, Çiftçi, Kafkas, Malazgirt, Seyran and Özbek according to the phys...
Enhanced salt tolerance of transgenic tobacco expressing a wheat salt tolerance gene

Soil salinity is one of the most important limiting factors of agricultural productivity in the world. The Triticum aestivum salt tolerance-related gene (TaSTRG) possesses a functional response to salt and drought stress conditions. A variety of stress factors, such as salt, drought, abscisic acid, and cold, may induce the expression of TaSTRG in wheat. In this study, the TaSTRG gene was transferred to tobacco via Agrobacterium-mediated transformation. Overexpression of TaSTRG in transgenic tobacco plants i...

Potato production is often constrained by abiotic stresses such as drought and high temperatures which are often present in combination. In the present work, we aimed to identify key mechanisms and processes underlying single and combined abiotic stress tolerance by comparative analysis of tolerant and susceptible cultivars. Physiological data indicated that the cultivars Desiree and Unica were stress tolerant while Agria and Russett Burbank were stress susceptible. Abiotic stress caused a greater reduction...
Stress Response Kinetics of Two Nisin Producer Strains of Lactococcus lactis spp. lactis
Simsek, Oemer; BUZRUL, Sencer; Akkoc, Nefise; Alpas, Hami; Akcelik, Mustafa (Springer Science and Business Media LLC, 2009-08-01)
The purpose of this study is to determine the survival and nisin production behaviors of two strains of Lactococcus lactis under different stress conditions that represent the food ecosystem. In this respect, the survival ratios of two nisin producers were determined under different pH, temperature, NaCl, and bile salt concentrations. Then, nisin production levels of the strains were determined at each stress conditions. Both strains had similar growth or inactivation patterns under the same stress conditio...
Integrated nutrient removal and biogas production by Chlorella vulgaris cultures
Calicioglu, Ozgul; Demirer, Göksel Niyazi (AIP Publishing, 2015-05-01)
Changes in global nutrient cycles as a result of industrialization affect both ecosystems and human well-being. A clear example of human manipulation on ecosystems is eutrophication; a phenomenon caused in receiving water bodies by discharge of urban sewage rich in nutrients such as nitrogen (N) and phosphorus (P). Microalgal nutrient removal is a viable alternative for biological wastewater treatment, considering high nutrient uptake capabilities of microalgae. These systems are also advantageous in terms ...
