Respiratory burst oxidase-D Expression and Biochemical Responses in Festuca arundinacea under Drought Stress

Physio-biochemical and Enzymatic Responses of Sunflower to Drought Stress

Drought stress is a serious adverse factor that limits sunflower growth and productivity. The stress induces a range of physiological and biochemical responses in sunflower. So, evaluation of defense systems is important for producing resistant cultivars. In this study, physio-biochemical changes and antioxidant enzymes activitiesof six sunflower lines were evaluated under normal and irrigation...

Germination, Physiological Responses and Gene Expression of Tall Fescue (Festuca arundinacea Schreb.) Growing under Pb and Cd

Cadmium (Cd) and lead (Pb) are recognized as the most toxic metal ions due to their detrimental effects not only to plants, but also to humans. The objective of this study was to investigate the effects of Cd and Pb treatments on seed germination, plant growth, and physiological response in tall fescue (Festuca arundinacea Schreb.). We employed six treatments: CK (nutrient solution as control),...

Ergovaline levels in cultivars of Festuca arundinacea

Differential gene expression in Festuca under heat stress conditions.

Fescues (Festuca sp.) are major cool-season forage and turf grass species around the world. Heat stress is one of the limiting factors in the production of fescues as forage in the southern Great Plains of the US. Heat responsive gene transcripts were cloned by using suppression subtractive hybridization between a heat-tolerant and a heat-sensitive fescue genotype subjected to a slowly increase...

Morphophysiological and biochemical changes in tall fescue (Festuca arundinacea Schreb.) under combined salinity and deficit irrigation stresses

Water salinity and drought are the major abiotic stresses limiting turf grass growth. On the other hand, shortage of waterresources and salinity of water and soil in the arid and semi-arid zones such as Iran, are the restricting factors in developinglawn turf grasses. An experiment was conducted to evaluate the combined effects of water salinity and deficit irrigation ontall fescue (Festuca aru...
