Carbon Monoxide Alleviates Salt-Induced Oxidative Damage in by Inducing the Expression of Proline Biosynthesis and Antioxidant Genes.

Crop growth and yield are affected by salinity, which causes oxidative damage to plant cells. Plants respond to salinity by maintaining cellular osmotic balance, regulating ion transport, and enhancing the expression of stress-responsive genes, thereby inducing tolerance. As a byproduct of heme oxygenase (HO)-mediated degradation of heme, carbon monoxide (CO) regulates plant responses to salinity.

Seed Priming with MeJa Prevents Salt-Induced Growth Inhibition and Oxidative Damage in by Inducing the Expression of Jasmonic Acid Biosynthesis Genes.

Salinity is one of the major detrimental abiotic stresses at the forefront of deterring crop productivity globally. Although the exogenous application of phytohormones has formerly proven efficacious to plants, their effect on the moderately stress-tolerant crop "" remains elusive. To investigate this, seeds primed with methyl jasmonate (0; 10 and 15 μM MeJa) were exposed to salt (200 mM NaCl) stress, and their morpho-physiological, biochemical, and molecular attributes were measured.

Green Synthesis of Iron Oxide (Hematite) Nanoparticles and Their Influence on Growth under Drought Stress.

Drought is a major abiotic stress that confronts plant growth and productivity, thus compromising food security. Plants use physiological and biochemical mechanisms to cope with drought stress, but at the expense of growth. Green-synthesized nanoparticles (NPs) have gained great attention in agriculture due to their environmental friendliness and affordability while serving as potential biofertilizers.
