Summary Soil salinity is a severe abiotic stress that damages plant growth and development. As an antioxidant free radical scavenger, melatonin well known for helping plants survive conditions, including stress. Here, we report the salt‐related gene MsSNAT1 , encoding rate‐limiting biosynthesis enzyme, located in chloroplast contributes to tolerance alfalfa. We found overexpressing alfalfa lines exhibited higher endogenous levels increased salt by promoting systems improving ion homeostasis. Furthermore, through combination of transcriptome sequencing, dual‐luciferase assays transgenic analysis, identified basic leucine zipper (bZIP) transcription factor, MsbZIP55, associated with response expression. EMSA analysis ChIP‐qPCR uncovered MsbZIP55 can recognize directly bind promoter vitro vivo . acts as negative regulator expression, thereby reducing biosynthesis. Morphological revealed conferred sensitivity Na + /K ratio lower activities, which could be alleviated applying exogenous melatonin. Silencing RNA interference resulted expression promoted enhancing system enzyme activities Our findings indicate MsbZIP55‐MsSNAT1 module plays crucial role regulating while facilitating protection against These results shed light on regulatory mechanism related

Global climate changes cause extreme temperatures and a significant reduction in crop production, leading to food insecurity worldwide. Temperature extremes (including both heat cold stresses) is one of the most limiting factors plant growth development severely affect physiology, biochemical, molecular processes. Biostimulants like melatonin (MET) have multifunctional role that acts as “defense molecule” safeguard plants against noxious effects temperature stress. MET treatment improves tolerance by improving several defense mechanisms. Current research also suggests interacts with other molecules, phytohormones gaseous which greatly supports adaptation Genetic engineering via overexpression or CRISPR/Cas system biosynthetic genes uplifts levels transgenic enhances stress tolerance. This review highlights critical production We documented how molecules alleviate MET-mediated breeding would be great potential helping adverse creating plants.

Increasing food demand by the growing human population and declining crop productivity due to climate change affect global security. To meet challenges, developing improved crops that can tolerate abiotic stresses is a priority. Melatonin in plants, also known as phytomelatonin, an active component of various cellular mechanisms alleviates oxidative damage hence supporting plant survive stress conditions. Exogenous melatonin strengthens this defence mechanism enhancing detoxification reactive by-products, promoting physiological activities, upregulating stress-responsive genes alleviate during stress. In addition its well-known antioxidant activity, protects against regulating hormones, activating ER genes, increasing protein homoeostasis, heat shock transcription factors proteins. Under stress, enhances unfolded response, endoplasmic reticulum-associated degradation, autophagy, which ultimately protect cells from programmed cell death promotes repair resulting increased survival.

Plants being sessile in nature, are exposed to unwarranted threats as a result of constantly changing environmental conditions. These adverse factors can have negative impacts on their growth, development, and yield. Hormones key signaling molecules enabling cells respond rapidly different external internal stimuli. In plants, melatonin (MT) plays critical role the integration various signals activation stress-response networks develop defense mechanisms plant resilience. Additionally, tackle stress-induced alteration cellular redox equilibrium by regulating expression hemostasis-related genes proteins. The purpose this article is compile summarize scientific research pertaining MT's effects plants' resilience biotic abiotic stresses. Here, we summarized that MT exerts synergistic effect with other phytohormones, for instance, ethylene, jasmonic acid, salicylic activates defense-related against phytopathogens. Furthermore, interacts secondary messengers like Ca2+, nitric oxide, reactive oxygen species regulate network. This interaction triggers transcription alleviate stress-related responses plants. Hence, synergic diverse hormones demonstrates phytomelatonin's importance influencing multiple contribute harsh factors.

The biosynthesis of secondary metabolites (SMs) in plants occurs various forms and amounts, their use modern medicine is widespread. Half the human necessities are derived from plant-based commodities, including fuel, cosmetics, pharmaceuticals, building materials, food essentials. Many medicinal plant species utilized for therapeutic properties SMs content, but amount naturally occurring limited. Therefore, conventional novel strategies employed to enhance production bioactive components plants. Traditional methods cost-effective, easy, faster, produce fewer metabolites, while techniques such as metabolic pathways engineering, genome editing, transformation, biotechnology-based substitutions, synthetic biology more expensive offer valuable tools augmenting content. Optimizing culture media signalling involved presents an exciting opportunity increase quantity compounds present. This review summarizes different cultivation used class produced highlights benefits boosting synthesizing using techniques.
