“…Salt stress, like other environmental stresses, induces the accumulation of reactive oxygen species (ROS) such as hydrogen peroxide (H2O2), superoxide (O2 -), and hydroxyl radicals (OH-) (Sekmen et al, 2013 oxidative damage for plant tissues in various ways (e.g., decrease in chlorophyll content, damage to cell membrane, protein oxidation, strand breaks in nucleic acids, etc. ), leading finally to cell death.…”

Amino acids, being the primary products of inorganic assimilation and precursors of proteins, play an essential role in plant metabolism. The objective of this study was to compare guar plants which were grown under salt-stress conditions (150 mM NaCl), in terms of the effect of different amino acid treatments (300, 600, 1200, and 1800 mg L -1 amino acid) on physiological, morphological, and enzymatic activity. Amino acid (AA) applications significantly increased fresh and dry weight, relative water content, photosynthetic pigments, total phenolic, flavonoid and free amino acid contents, K + and Ca ++ ion concentration, ascorbate peroxidase (APX), catalase (CAT), glutathione reductase (GR), and superoxide dismutase (SOD) activity of guar plants compared to the salt stress treatment the ones under no AA treatment. According to the results, the malondialdehyde (MDA) content, Na + and Clion contents were significantly decreased. Hence, the results support the application of the amino acid in 600 mg L -1 doses in order to increase the defense system of the guar plant, enabling it to tolerate the negative effects induced by salinity.

“…SOD is localized in almost all cellular compartments and the water-water cycle in chloroplasts. The components of the ascorbate-glutathione cycle are localized in chloroplasts, cytosol, mitochondria, and apoplast, while both glutathione peroxidase (GPX) and CAT are localized in peroxisomes (Sekmen et al, 2013).…”

“…Ionic stress is caused by an increased accumulation of ions, which affects the metabolic homeostasis Zhu, 2001). The osmotic stress effect is characterized by a rapid inhibition of growth rate of young leaves, while the ionic effects typically result in an increased rate of senescence in older leaves (Sekmen et al, 2013). Our knowledge on how a plant senses salt stress is meager.…”

“…These mechanisms help plants to survive and maintain growth under unfavorable conditions. Examples of traits found in these specialized halophytic species are salt glands extruding salt on the leaves (for instance, in Avicennia marina, a mangrove species) and well developed Casparian strips with early vacuolation and suberization of the hypo-and endodermis in roots (for instance in Suaeda maritima, Seepweed) (Sekmen et al, 2013).…”
