Globally from abiotic stresses, salt stress is the major stress that limits crop production. One of them is wheat that has been utilized by more than 1/3 of the world population as staple food due to its nutritive value. Biochar is an activated carbon that can ameliorate the negative impacts on plants under saline conditions. The present study was conducted to examine the ameliorative impact of "Biochar application" to Triticum aestivum L. plant grown under salinity stress and evaluated on the basis of various growth, yield, physiological, biochemical attributes. Preliminary experiment was done to select the Triticum aestivum L. varieties with 90% germination rate for further experiment. The selected varieties, FSD08 and PUNJAB-11 of wheat were treated with two levels of sodium chloride (0 mM and 120 mM). Two varieties of wheat included FSD08 and PUNJAB-11 were treated with two levels of sodium chloride (0 mM and 120 mM). To address the impact of salt stress two levels of biochar 0% and 5% was used as exogenous application. A three way completely randomized experimentation was done in 24 pots of two wheat varieties with three replicates. The results demonstrated that salt stress affected growth, physiological attributes, yield and inorganic mineral ions (Ca and K) in roots and shoots parameters of wheat negatively while biochar overall improved the performance of plant. SOD, CAT, APX and POD activities enhanced during salt stress as the plant self-defense mechanism against salinity to minimize the damaging effect. Salt stress also significantly increased the membrane permeability, and levels of HO, MDA, Cl and Na ions. Biochar treatment nullified negative impacts of NaCl and improved the plant growth and yield significantly. Hence, biochar amendment can be suggested as suitable supplement for sustainable crop production under salinization.

We herein investigated the effects of salt (NaCl) stress on soybean nodulation by rhizobial strains. We specifically exami-ned: (1) the effects of NaCl on nodule maturity and positioning by inoculating three rhizobial strains (Bradyrhizobium diazoefficiens USDA110, Bradyrhizobium elkanii USDA31, and Sinorhizobium fredii USDA191) onto soybean variety CNS, (2) the effects of the NaCl treatment on isoflavones (daidzein and genistein) secretion by CNS, (3) the effects of the NaCl treatment on gene expression induced by daidzein and genistein in rhizobia, and (4) the effects of the NaCl treatment on rhizobial growth. The results obtained were as follows: (1) the NaCl treatment delayed nodule development and reduced nodulation on the primary root following the USDA110 inoculation, minimal sensitivity regarding nodule formation in the USDA 31 inoculation, and significantly increased the mature nodule number and nodules on the primary root following the USDA 191 inoculation.

Perennial ryegrass (Lolium perenne) is a widely cultivated forage and turf grass species. Salt stress can severely damage the growth of grass plants. The genome-wide molecular mechanisms of salt tolerance have not been well understood in perennial grass species.

Background: Trehalose is a nonreducing disaccharide containing two glucose molecules linked through an α,α-1,1-glycosidic bond. This unique chemical structure causes trehalose levels to fluctuate significantly in plants under stress, where it functions as an osmoprotectant, enhancing plant resistance to stress. Previous studies have confirmed that the trehalose synthesis pathway is widely conserved across most plants.
