Salinity poses a significant threat to the floral plants. Melatonin has emerged as potential phytohormone cope with adverse effects of salinity on plants due its multifaceted roles in regulating abiotic stresses. The current study aimed investigate impact melatonin pansy by modifications physiological indices under stress. Pansy were subjected stress (0, 50, and 100 mM NaCl) (control, µM).

Abstract Seed germination (SG) is the first stage in a plant's life and has an immense importance sustaining crop production. Abiotic stresses reduce SG by increasing deterioration of seed quality, reducing potential, vigor. Thus, to achieve sustainable level yield, it important improve under abiotic stress conditions. Melatonin (MEL) biomolecule that interplays developmental processes regulates many adaptive responses plants, especially stresses. this review specifically summarizes discusses mechanistic basis MEL‐mediated MEL regulating some stress‐specific common responses. For instance, induced specific include regulation ionic homeostasis, hydrolysis storage proteins salinity stress, C‐repeat binding factors signaling cold starch metabolism high temperature heavy metal activation aquaporins accumulation osmolytes drought stress. On other hand, mediated gibberellins biosynthesis abscisic acid catabolism, redox Ca 2+ are amongst Nonetheless such as endogenous contents, plant species, growth conditions also influence above‐mentioned In conclusion, interacting with different physiological mechanisms.

Salinity or salt stress has deleterious effects on plant growth and development. It imposes osmotic, ionic, secondary stresses, including oxidative the plants is responsible for reduction of overall crop productivity therefore challenges global food security. Plants respond to salinity, by triggering homoeostatic mechanisms that counter salt-triggered disturbances in physiology biochemistry plants. This involves activation many signaling components such as SOS pathway, ABA ROS osmotic signaling. These biochemical responses are accompanied transcriptional modulation stress-responsive genes, which mostly mediated salt-induced transcription factor (TF) activity. Among TFs, multifaceted significance WRKY proteins been realized diverse avenues plants’ life regulation response. Therefore, this review, we aimed highlight salinity a perspective, mechanism sensing plants, contribution WRKYs response stress. review will be substantial tool investigate problem different perspectives, targeting offering directions better manage field ensure

Abstract Drought, a major factor limiting global crop yields, disrupts plant growth, water interactions, and overall use efficiency. Hydrogen sulfide (H 2 S), key gasotransmitter, has become crucial signalling molecule in biology. It promotes growth development while significantly contributing to the plant's response various abiotic stresses, including drought. This review explores how H₂S mitigates drought stress plants crosstalks with molecules such as nitric oxide, melatonin, abscisic acid, γ‐aminobutyric polyamines, others. highlights these acting either upstream or downstream, enhance resistance. Furthermore, involves persulfidation, which modifies protein thiol groups protect against oxidative damage. The underscores role of persulfidation reducing reactive oxygen species accumulation maintaining redox homeostasis under stress. aims elucidate relief expand our knowledge it contributes resistance during scarcity by examining its regulatory mechanisms interactions. Additionally, proposes practical strategies for enhancing agricultural practices face growing conditions, offering methods leverage improving tolerance scarcity.
