In recent years, the use of priming agents, such as silicon, melatonin, salicylic acid, glycine betaine, and ascorbic acid has gained significant attention for their role in mitigating abiotic stresses across various plant species. While previous research been conducted on individual impact metal stress resistance among crop species, combined effects context heavy stressed conditions remain underexplored. Wheat (Triticum aestivum L.) seedlings was grown under toxic concentration copper (Cu) i.e., 100 µM which were applied with hydroponic 21 days. The outcomes indicated that Cu nutrient solution notably reduced growth biomass, photosynthetic pigments, gas exchange attributes. However, also induced oxidative plants by increasing malondialdehyde (MDA), hydrogen peroxide (H2O2) increased compounds enzymatic non-enzymatic antioxidants, health risk index (HRI) gene expression sugar content. Furthermore, a increase proline metabolism, AsA-GSH cycle, pigmentation cellular components observed. Although, application different showed characteristics, compounds, decreased HRI. addition, agents enhanced fractionation metabolism cycle T. seedlings. These results open new insights sustainable agriculture practices hold immense promise addressing pressing challenges contamination agricultural soils.

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.

Proline, a critical osmoregulatory compound, is integral to various plant stress responses. The P5CS gene, which encodes the rate-limiting enzyme in proline biosynthesis, known as ∆1-pyrroline-5-carboxylate synthetase, fundamental these response pathways. While functions of genes plants have been extensively documented, their specific roles cotton remain inadequately characterized. In this study, we identified 40 across four species with diverse sequence lengths and molecular weights. Phylogenetic analysis 100 from nine revealed three subgroups, Gossypium hirsutum closely related barbadense. Collinearity highlighted significant differences collinear gene pairs, indicating evolutionary divergence among tetraploid diploid cotton. Exon–intron structures conserved motifs correlated phylogenetic relationships, suggesting functional differentiation. Stress-responsive elements promoters suggest involvement abiotic stress. Expression under salt differential expressions GhP5CS genes, GhP5CS1 emerging potential key regulator. Virus-induced silencing confirmed pivotal role cotton’s response, evidenced by increased sensitivity silenced plants. This study enhances our understanding diversity conditions.
