Cytosolic and Chloroplastic DHARs Cooperate in Oxidative Stress-Driven Activation of the Salicylic Acid Pathway.
The complexity of plant antioxidative systems gives rise to many unresolved questions. One relates to the functional importance of dehydroascorbate reductases (DHARs) in interactions between ascorbate and glutathione. To investigate this issue, we produced a complete set of loss-of-function mutants for the three annotated Arabidopsis (Arabidopsis thaliana) DHARs. The combined loss of DHAR1 and ...
متن کاملEffect of salicylic acid on photochemistry and antioxidant capacity in Salvia nemorosa plants subjected to water stress.
Oxidative stress is commonly induced when plants are grown under drought stress conditions.To analyze how salicylic acid (SA) can partly alleviate drought-induced oxidative stress and negative impacts of drought on physiology and growth of Salvia nemorosa plants, we investigated the physiological responses of S. nemorosa to SA application under drought stress. The treatments were composed of Co...
متن کاملEffect of salicylic acid on cabbage (Brassica oleracea var. Capitata) grown under salinity stress. Sunaina and Narsingh Bahadur Singh*
The effects of salicylic acid (SA) on growth and metabolism of Brassica oleracea var. Capitata under salt stress was studied in a hydroponic culture. NaCl at 50 mM concentration and SA at 0.5, 1.0, and 1.5mM concentrations were used as treatments. The results showed that salt exhibited inhibitory effects on shoot and root length, fresh and dry weight, and RWC of the seedlings. NaCl at 50 mM co...
متن کاملFunctional divergence in the glutathione transferase superfamily in plants. Identification of two classes with putative functions in redox homeostasis in Arabidopsis thaliana.
Searches with the human Omega glutathione transferase (GST) identified two outlying groups of the GST superfamily in Arabidopsis thaliana which differed from all other plant GSTs by containing a cysteine in place of a serine at the active site. One group consisted of four genes, three of which encoded active glutathione-dependent dehydroascorbate reductases (DHARs). Two DHARs were predicted to ...
متن کاملEffect of Salicylic Acid Application on Oxidative Damage and Antioxidant Activity of Grape (Vitis vinifera L.) Under Drought Stress Condition
Adaptation and defense responses are the consequences of exposure to drought stress in plants. Salicylic acid (SA) as a natural signaling molecule poses a significant impacts on various aspects of plant growth and development. This study investigates the effects of SA on carotenoids content, lipid peroxidation rate and antioxidant enzymes activities. A pot experiment was conducted using a facto...
