Abstract Salinity stress has become a major threat to worldwide crop production. Exogenous melatonin (MT) appeared as promising treatment against salt in several plant species. However, MT effect on the tolerance of sorghum plants under different saline conditions (moderate and severe) remains ambiguous. This study was carried out explore impact (0, 50, 100 200 µM) foliar application seedlings grown moderate severe using sodium chloride, NaCl (75 150 µM NaCl). treatments were applied solution sand medium pots. The results demonstrated that rising salinity level negatively affected growth, photosynthetic pigments (chlorophylls carotenoids), leaf water status ionic homeostasis (sodium, potassium, calcium ions). Applied-MT specifically at or enhanced osmotic balance, cell membrane stabilizing relative content. These effects associated with an obvious restriction hydrogen peroxide, lipid peroxidation (malondialdehyde content) methylglyoxal. Moreover, antioxidant activities peroxidase, catalase, superoxide dismutase, ascorbate peroxidase enzymes modulated by treatments. Molecular docking modeling assessment illustrated top-ranked confirmations between target enzymes. forms multiple bonds key amino acid residues for glycine (A: 162), tryptophan 41), leucine 165), tyrosine 235) active site peroxidase. alkyl interactions 37), arginine 38) cysteine 168) also contribute its high affinity. Despite is commonly moderately tolerant stress, this confirmed sensitivity wide range early growth stages. Melatonin spraying led improvements various morphological, physiological biochemical mechanisms harmonized together confer resistance salt-stressed seedlings.

Abstract Background Abiotic stresses, like drought, are the major cause of shrinking plant, growth crop yields and quality. Nanotechnology has provided a significant improvement in increasing plant yield crops under stress conditions. This work assessed potential silicon for mitigating negative effects drought against wheat.

Abstract Salinization, as a serious climate change phenomenon, continues to cause critical issues for soils and crops. Abundance of genetic diversity plants could contribute in solving the impacts salinity. However, relations between physiological molecular traits plant species need deep investigation interpretation. Pot experiments were conducted greenhouse investigate difference behavior two amaranth when they beforehand subjected salinity-stress conditions, specifically on some specific characteristics. After 45 days from transplanting, salt stress was induced using 150 mM sodium chloride solution. Treatments arranged randomized complete block design three replications. 0, 2, 6, 10, 24 h, samples collected evaluate data well gene expression. The immediately frozen liquid nitrogen stored -80⁰ C ultralow temperature refrigerators. Findings revealed that red ( Amaranthus cruentus ) more tolerant saline than green hypochondriacus ). Result malondialdehyde (MDA) content increased after 2 h then decreased (after 6 10 h) before rising again h. In amaranth, MDA initially increasing later decreasing zigzag pattern ending an increase There initial steep rise proline which continued still moderately till it stopped. Results also showed gave higher value superoxide dismutase (SOD) activity compared with all tested salinity exposure times. expression four genes assessed through quantitative PCR indicated efficiency SOS1, HKT1, NHX1, DGR2 genes, encode adaptation-related proteins under stress. summary, current work demonstrated be efficient resource improving salt-tolerant genotypes belonging genus.
