mammalian ∆-(1)-pyrroline-5-carboxylate synthase (p5cs) enzyme catalyzes the coupled phosphorylation and reduction-conversion of glutamate to ∆-(1)-pyrroline-5-carboxylate (p5c), a critical step in the proline, ornithine, citrulline and arginine biosynthesis. in plants and mammals, p5cs consists of two separate enzymatic domains: n-terminal γ-glutamyl kinase (γ-gk) and c-terminal γ-glutamyl pho...

The aim of this experiment was to investigate the exogenous application salicylic acid (SA) on morpho-physiological and molecular characteristics Impatiens walleriana plants grown under water deficit stress. Three levels soil contents (95, 85, 75% field capacity; FC) three SA (0, 1, 2 mM) were applied two impatient cultivars (‘Tempo’ ‘Salmon’). results showed that increasing stress negatively a...

In a series of experiment, the response of two contrasting potato species, namely,  Solanum acaule (tolerant) and Solanum tuberosum cv. Agria (intolerant) to salt (80 mM NaCl) and drought stress (15% polyethylene glycol;PEG) was studied in vitro. Furthermore, the role of acetyl salicylic acid (ASA) (1 and 10 µM) in alleviating oxidative stress was investigated. In Agria cultivar, NaCl and PEG r...

salinity is a major limiting factor for plant growth and development. to evaluate the impact of p5cs gene expression under in vitro salt stress condition, transgenic tobacco (nicotiana plumbaginifolia) carrying p5cs gene and non-transgenic plants were treated with 0, 100, 150, 200 or 250 mm nacl for 28 days. proline content, lipid peroxidation and the activity of some antioxidant enzymes after ...

this study was carried out to investigation the possibility of using triadimefon (trd) in order to decrease the adverse effects of salt stress on medicago plant. triadimefon is a member of triazol compounds which enhances stress tolerance through physiological processes. two cultivars of medicago sitiva including hamedani and yazdi were used in this study. plants were treated with 1, 2 and 4 mg...

Serotonin and melatonin, which are indolamines present in every biological kingdom, show strong bioregulator activity plant tissues under various stress conditions. Although numerous studies have reported the mitigating effects of effect serotonin on physiology has rarely been studied current literature. In this study, exogenous application tomato seedlings severe salt drought stresses were inv...
