The seed pretreatment with salicylic acid has an important role in improving seed germination and increasing plant resistance to environmental stresses. This study was performed to investigate the effect of salicylic acid on seed germination of Milk thistle under salinity and drought stress. A factorial experiment was conducted in a completely randomized design with three replications. Treatmen...
Salt stress is one the major environmental stresses limiting quantitative and qualitative aspects of plant growth. One of the methods to overcoming the adverse effects of salinity is application of growth regulators. Salicylic acid is a plant growth regulator its positive effects in alleviating the adverse effects of stresses on plants have been reported. In order to study the effect of salicyl...
Diplotaxis tenuifolia L. is of important economic value in the fresh-cut industry for its nutraceutical and sensorial properties. However, information on the molecular mechanisms conferring tolerance of harvested leaves to pre- and postharvest stresses during processing and shelf-life have never been investigated. Here, we provide the first transcriptomic resource of rocket by de novo RNA seque...
Soybean nodulin 26 is expressed and targeted to the symbiosome membrane of nitrogen-fixing nodules, where it forms an aquaporin channel with a modest water transport rate. In this study, we show that the phosphorylation of nodulin 26 on Ser-262, which is catalyzed by a symbiosome membrane-associated calcium-dependent protein kinase, stimulates its intrinsic water transport rate. Furthermore, us...
A glasshouse study was conducted to measure the effects of salinity and drought stresses on growth and chemical and biochemical composition of 4 onion cultivars. The cultivars were Dessex, Texas Early Grano (Texas), Dehydrator, and PX492. Salinity treatments included control, 45mM NaCl, 45mM NaCl + 5mM CaCl2 and drought treatments were control (maintaining soil moisture at field capacity) and...

Extended abstract Introduction: Using of plant growth regulators is one of the methods can improve plant growth against environmental stresses such as salinity. Salicylic acid plays an important role in physiological processes regulation, including germination. Today, using of growth promoting bacteria has been increased and it causes to raise the seed vigor, uniformity, germination percentage...
Salinity and low nitrogen availability are two major abiotic stresses that often coexist disturb plant productivity. This study aimed at investigating the combined effects of salinity (0 100 mM NaCl) (0.5 5.0 NH4NO3) levels on morphological parameters, mineral status, use efficiency, photosynthesis, nitrate reductase (NR, E.C. 1.6.6.1) glutamine synthetase (GS, EC 6.3.1.2) activities Sulla carn...
Soil salinity is major abiotic stresses affecting morphological, biochemical and physiological processes of plant growth. Chryseobacterium gleum sp. SUK isolated from salt-stressed soil exhibited ACC (1-aminocyclopropane-1-carboxylate) deaminase activity with IAA (indole acetic acid), siderophore, ammonia, hydrogen cyanide production, 2% salt tolerance and fungal cell wall degrading enzyme prod...
to evaluate interaction of salinity stress and nitrogen use methods on yield and yield components, in experiment was conducted in split plot in randomized complete block with 3 replications. treatments included: salinity of irrigation water levels 1.5, 4.4 and 7.9 ds/m as main plots, and nitrogen treatments 1. using n fertilizer at 3 stage in soil, 2. using two third n fertilizer in soil at pla...
