Ensuring food security is one of the main challenges related to a growing global population under climate change conditions. The increasing soil salinity levels, drought, heatwaves, and late chilling severely threaten crops often co-occur in field This work aims provide deeper insight into impact single vs. combined abiotic stresses at growth, biochemical photosynthetic levels Arabidopsis thaliana (L.). Reduced QY max was recorded salinity-stressed plants, NPQ increased heat stresses, qP decreased stresses. MDA H2O2 content were consistently altered all stress conditions, but higher values alone combination. Salinity combinations (especially with cold) provided stronger hierarchical effect. Despite glycine GABA osmolytes not significantly changing, proline highlighted hierarchically salinity, while glycine-betaine drought combinations. Untargeted metabolomics pointed out distinct metabolic reprogramming triggered by different or Pathway analysis revealed that affected hormones, amino acids derivates, secondary metabolites.

Salt stress impacts phosphorus (P) bioavailability, mobility, and its uptake by plants. Since P is involved in many key processes plants, salinity deficiency could significantly cause serious damage to photosynthesis, the most essential physiological process for growth development of all green Different approaches have been proposed adopted minimize harmful effects their combined effect. Optimising nutrition seems bring positive results improve photosynthetic efficiency nutrient uptake. The present work posed question if soluble fertilizers allow wheat plants counter adverse effect salt stress. A pot experiment was performed using a Moroccan cultivar durum wheat: Karim. This study focused on different responses grown under P-availability. Two Orthophosphates (Ortho-A & Ortho-B) one polyphosphate (Poly-B) were applied at levels (0, 30 45 ppm). Plant analysed some parameters (stomatal conductance (SC), chlorophyll content index (CCI), fluorescence, shoot root biomass, mineral uptake).

The application of bio- and nanofertilizers are undoubtedly opening new sustainable approaches toward enhancing abiotic stress tolerance in crops. In this study, we evaluated the effective microorganisms (EMs) five groups belonging to photosynthetic bacteria, lactic acid yeast, actinobacteria, fermenting fungi combined with magnesium oxide (MgO) nanoparticles (MgO-NP) on growth productivity sweet potato plants grown salt-affected soils. two field experiments carried out 2020 2021, tested impacts EMs using treatments (with vs. without as soil drench) coupled three foliar applications MgO-NP (0, 50, 100 μg ml –1 MgO, representing 0 , 50 respectively). our efforts investigate EMs:MgO-NP effects, performance (growth yield), nutrient acquisition, physio-biochemical attributes potatoes (7.56 dS m ) were assessed. Our results revealed that salinity significantly reduced parameters, yield traits, pigment content (chlorophylls a b carotenoids), cell membrane stability, relative water content, acquisition potatoes. However, + and/or MgO-NP-treated showed high salt stress, specifically relatively superior increase when any biostimulants combined. improved osmotic by increasing integrity. These positive responses owed osmolytes level (proline, free amino acids, soluble sugars) antioxidative compounds (non-enzymatic concentration, enzymatic activities, phenolic acid, carotenoids). We also noticed increased Na whereas EMS exhibited lower concentration K /Na ratio. improvements contributed pigments, growth, under stress. integrative higher efficacy bypassing all single treatments. findings indicated potential coapplying for future use attenuating salt-induced damage beneficially promoting crop performance.

Soil microbiota can confer fitness advantages to plants and increase crop resilience drought other abiotic stressors. However, there is little evidence on the mechanisms correlating a microbial trait with plant stress tolerance. Here, we report that Streptomyces effectively alleviate salinity by producing spiroketal polyketide pteridic acid H (1) its isomer F (2), both of which promote root growth in Arabidopsis at concentration 1.3 nM under stress. Transcriptomics profiles show increased expression multiple responsive genes seedlings after acids treatment. We confirm vivo bifunctional biosynthetic gene cluster for antimicrobial elaiophylin production. propose it mainly disseminated vertical transmission geographically distributed various environments. This discovery reveals perspective understanding plant-Streptomyces interactions provides promising approach utilising beneficial their secondary metabolites agriculture mitigate detrimental effects climate change.

This study aimed to explore how exogenous proline induces salinity tolerance in celery. We analyzed the effects of foliar spraying with 0.3 mM on celery growth, photosystem, phenolic compounds, and antioxidant system under salt stress (100 NaCl), using no as control. The results showed that proline-treated plants exhibited a significant increase plant biomass due improved growth physiology, supported by gas exchange parameters, chlorophyll fluorescence, Calvin cycle enzyme activity (Ketosasaccharide-1,5-diphosphate carboxylase Fructose-1,6-diphosphate aldolase) results. Also, significantly suppressed relative conductivity malondialdehyde content caused stress, suggesting reduction biological membrane damage. Moreover, resulted hydrogen peroxide, superoxide anions 4-coumaric acid accumulation celery, their contents were reduced after proline. Furthermore, increased enzymes (superoxide dismutase, peroxidase, catalase) non-enzymatic antioxidants (reduced ascorbic acid, glutathione, caffeic chlorogenic total acids, flavonoids). Additionally, key (ascorbate oxidase, ascorbate glutathione reductase, dehydroascorbate reductase) acid–glutathione cycle, activating it counteract stress. In summary, promoted enhanced photosynthesis, flavonoid contents, capacity, thereby improving
