Global climate change and the decreasing availability of high-quality water lead to an increase in salinization agricultural lands. This rising salinity represents a significant abiotic stressor that detrimentally influences plant physiology gene expression. Consequently, critical processes such as seed germination, growth, development, yield are adversely affected. Salinity severely impacts crop yields, given many plants sensitive salt stress. Plant growth-promoting microorganisms (PGPMs) rhizosphere or rhizoplane considered “second genome” they contribute significantly improving growth fitness under normal conditions when stress salinity. PGPMs crucial assisting navigate harsh imposed by By enhancing nutrient absorption, which is often hampered high salinity, these improve resilience. They bolster plant’s defenses increasing production osmoprotectants antioxidants, mitigating salt-induced damage. Furthermore, supply hormones like auxins gibberellins reduce levels hormone ethylene, fostering healthier growth. Importantly, activate genes responsible for maintaining ion balance, vital aspect survival saline environments. review underscores multifaceted roles supporting life stress, highlighting their value agriculture salt-affected areas potential impact on global food security.

Salinity stress (SS) is a serious abiotic and major constraint to agricultural productivity across the globe. High SS negatively affects plant growth yield by altering soil physio-chemical properties physiological, biochemical, molecular processes. The application of micronutrients considered an important practice mitigate adverse effects SS. Zinc (Zn) nutrient that plays imperative role in growth, it could also help alleviate salt stress. Zn improves seed germination, seedling water uptake, relations, homeostasis, therefore improving performance saline conditions. protects photosynthetic apparatus from salinity-induced oxidative stomata movement, chlorophyll synthesis, carbon fixation, osmolytes hormone accumulation. Moreover, increases synthesis secondary metabolites expression responsive genes stimulates antioxidant activities counter toxic Therefore, better understand plants under SS, we have discussed various mechanisms which induces salinity tolerance plants. We identified diverse research gaps must be filled future programs. present review article will fill knowledge on mitigating This readers learn more about provide new suggestions how this can used develop using Zn.

In environments with high levels of stress conditions, plants accumulate various metabolic products under conditions. Among these products, amino acids have a cardinal role in supporting and maintaining plant developmental processes. The increase proline content tolerance has been found optimistic, suggesting the importance mitigating through osmotic adjustments. Exogenous application pretreatment growth development stressful but excessive negative influence on growth. Proline two biosynthetic routes: glutamate or ornithine pathway, whether synthesize by precursors is still debatable as relatively little known about it. Plants innate machinery to from both pathways, switch particular pathway which it can be activated deactivated depends upon factors. Therefore, this review, we elucidate mitigation; optimal amount required for maximum benefit; at inhibits growth, factors that regulate biosynthesis; lastly, how benefit all answers obtain better plants.

Salt stress is one of the most severe environmental stresses limiting productivity crops, including rice. However, there a lack information on how salt-stress sensitivity varies across different developmental stages in In view this, comparative evaluation contrasting rice varieties CSR36 (salt tolerant) and Jaya sensitive) was conducted, wherein NaCl (50 mM) independently given either at seedling (S-stage), tillering (T-stage), flowering (F-stage), seed-setting (SS-stage) or throughout plant growth, from till maturity. Except for S-stage, exhibited improved tolerance than Jaya, all other tested stages. Principal component analysis (PCA) revealed that coincided with enhanced activities/levels enzymatic/non-enzymatic antioxidants (root ascorbate peroxidase T- (2.74-fold) S+T- (2.12-fold) root catalase F- (5.22-fold), (2.10-fold) S+T+F- (2.61-fold) stages) higher accumulation osmolytes (shoot proline F-stage (5.82-fold) (2.31-fold) stage), indicating better antioxidant capacitance osmotic adjustment, respectively. contrast, shoot Na+ (14.25-fold) consequent increase Na+/K+ (14.56-fold), Na+/Mg+2 (13.09-fold) Na+/Ca+2 (8.38-fold) ratio shoot, were identified as major variables associated S-stage salinity Jaya. Higher their deriving force stage specific combined addition, levels Fe3+, Mn2+ Co3+ lower Cl− SO42−, suggesting its potential to discriminate essential non-essential nutrients, which might contribute tolerance. Taken together, findings provided framework stage-specific responses rice, will facilitate crop-improvement programs ecological niches, coastal regions.

Salinity is a serious abiotic stress that limits crop production and food security. Micronutrient application has shown promising results in mitigating the toxic impacts of salinity. This study assessed zinc seed priming (ZSP) on germination, growth, physiological biochemical functioning sorghum cultivars. The comprised cultivars (JS-2002 JS-263), salinity (control (0 mM) 120 mM)), control ZSP (4 mM). reduced germination seedling growth by increasing electrolyte leakage (EL: 60.65%), hydrogen peroxide (H2O2: 109.50%), malondialdehyde (MDA; 115.30%), sodium (Na), chloride (Cl) accumulation decreasing chlorophyll synthesis, relative water contents (RWC), total soluble proteins (TSPs), potassium (K) uptake accumulation. Nonetheless, mitigated deleterious led to faster better growth. Zinc improved leaf contents, antioxidant activities (ascorbate peroxide: APX, catalase: CAT, peroxidase: POD, superoxide dismutase: SOD), TSPs, proline, K accumulation, EL, MDA, H2O2 production, as well ions (Na Cl), thereby promoting Thus, these findings suggested can mitigate toxicity favoring nutrient homeostasis, activities, osmolyte maintaining status.

A previous exposure to drought priming (DP) or salt (SP) could significantly improve future tolerance both the same and different abiotic stresses, which is an effective mitigation strategy for plants adapt changing environmental conditions. If type of stress from subsequent stress, this indicates that are trained acquire cross tolerance. The objective study was explore DP-regulated SP-induced associated with changes in growth, antioxidant defense, proline metabolism, expression dehydration-responsive gene Dehydrin b involved stabilization membrane systems, cryoprotection intracellular proteins, enhancement water retention capacity white clover (Trifolium repens). Plants were pretreated by initial DP SP then subjected 10 days, respectively. results demonstrated increased number roots during whereas improved stem length, root under indicated exhibited more pronounced positive effects on mitigating drought-induced growth retardant. Both resulted significant increases electrolyte leakage contents superoxide anion, hydrogen peroxide, malonaldehyde due reduced dismutase, catalase, as well key enzyme activities ascorbate–glutathione cycle. enhance these alleviate drought- salt-induced oxidative damage. also accumulation contributing better homeostasis promoting biosynthetic (Δ1-pyrroline-5-carboxylate synthetase aminotransferase) restricting dehydrogenase activity degradation In addition, up-regulated dehydrin but failed induce response stress. current findings proved pre-exposure effectively mitigate negative related some common pathways. adaption regulating physiological, metabolic, transcriptional changes.
