The negative impacts of soil salinization on ion homeostasis provide a significant global barrier to agricultural production and development. Plant physiology biochemistry are severely affected by primary secondary NaCl stress impacts, which damage cellular integrity, impair water uptake, trigger physiological drought. Determining how transcriptional factors (TFs) hormone networks regulated in plants response salt is necessary for developing crops that tolerate salt. This study investigates the complex mechanisms several TF families influence plant responses stress, involving AP2/ERF, bZIP, NAC, MYB, WRKY. It demonstrates these transcription help respond detrimental effects salinity modulating gene expression through including signaling, osmotic pathway activation, homeostasis. Additionally, it explores hormonal imbalances triggered entail interactions among phytohormones like jasmonic acid (JA), salicylic (SA), abscisic (ABA) within regulatory networks. review highlights role key salt-stress response, their interaction with hormones crucial genome-edited can enhance sustainability address food security challenges.

Salt stress inhibits plant growth by disturbing intrinsic physiology. The application of exogenous regulators to improve the tolerance against salt has become one promising approaches promote in saline environment. Eugenol (4-allyl-2- methoxyphenol) is main ingredient clove oil and it known for its strong antioxidant anti-microbial activities. also ability inhibiting several pathogens, implying potential use eugenol as an environmental friendly agrichemical. However, little about possible role regulation abiotic stress. Therefore, here we investigated effectiveness phytochemical promoting tobacco seedlings through physiological, histochemical, biochemical method. seedling roots were exposed NaCl solution presence or absence eugenol. inhibited growth, but supplementation effectively attenuated effects a dose-dependent manner, with optimal effect at 20 µM. ROS (reactive oxygen species) accumulation was found upon which further resulted amelioration lipid peroxidation, loss membrane integrity, cell death salt-treated seedlings. Addition highly suppressed reduced peroxidation generation. Both enzymatic non-enzymatic antioxidative systems activated treatment. AsA/DHA GSH/GSSG enhanced treatment, helped maintain redox homeostasis salinity. treatment increase content osmoprotectants (e.g. proline, soluble sugar starch) Na + levels decreased significantly exposure. This may result from upregulation expression two ionic transporter genes, SOS1 (salt-hypersensitive 1) NHX1 (Na /H anti-transporter 1).

ABSTRACT The metabolome, encompassing small molecules within organisms, provides critical insights into physiology, environmental influences, and stress responses. Metabolomics enables comprehensive analysis of plant metabolites, uncovering biomarkers mechanisms underlying adaptation. Regulatory genes such as MYB WRKY are central to secondary metabolite synthesis resilience. By integrating metabolomics with genomics, researchers can explore stress‐related pathways advance crop improvement efforts. This review examines metabolomic profiling under conditions, emphasizing drought tolerance mediated by amino acids organic acids. Additionally, it highlights the shikimate pathway's pivotal role in synthesizing metabolites essential for defense. These contribute understanding metabolic networks that drive resilience, informing strategies agricultural sustainability.

Salt stress is one of the dominant abiotic conditions that cause severe damage to plant growth and, in turn, limiting crop productivity. It therefore crucial understand molecular mechanism underlying root responses high salinity as such knowledge will aid efforts develop salt-tolerant crops. Alternative splicing (AS) precursor RNA important processing steps regulate gene expression and proteome diversity, consequently, many physiological biochemical processes plants, including stresses like salt stress. In current study, we utilized high-throughput RNA-sequencing analyze changes transcriptome characterize AS landscape during early response tomato Under conditions, 10,588 genes were found be differentially expressed, those involved hormone signaling transduction, amino acid metabolism, cell cycle regulation. More than 700 transcription factors (TFs), members MYB, bHLH, WRKY families, potentially regulated events greatly enhanced under stress, where exon skipping was most prevalent event. There 3709 identified alternatively spliced (DAS), prominent which serine/threonine protein kinase, pentatricopeptide repeat (PPR)-containing protein, E3 ubiquitin-protein ligase. 100 DEGs implicated spliceosome assembly, may salt-responsive roots. This study uncovers stimulation provides a valuable resource for future studies improve tolerance.

Under NaHCO3 stress, exogenous 24-epibrassinolide (EBR) markedly alleviated Na+ accumulation in cucumber plants, thereby decreasing the Na+/K+, Na+/Mg2+, and Na+/Ca2+ ratios. This mitigation was accompanied by elevated concentrations of K+, Ca2+, Mg2+, as well enhanced expression NHX SOS1 genes. In addition, activities plasma membrane H+-ATPase, vesicular H+-PPase were significantly increased, contributing to maintenance ionic balance plants. stress disrupted nitrogen metabolism, evidenced reductions NR, GS, GOGAT, GOT, GPT, along with altered GDH activity. These disruptions led an NH4+ substantial decreases NO3−-N total content. Exogenous EBR these effects enhancing countering prolonged suppression activity, restoring levels. Consequently, application reduced toxicity induced alkali stress. Additionally, increased ABA while IAA GA3 content seedlings. contrast, levels IAA/ABA GA3/ABA ratios, thus maintaining hormonal equilibrium under Collectively, findings highlight that enhances alkaline tolerance plants regulating ion homeostasis, phytohormonal responses.

Chinese cabbage is an important leafy vegetable crop with high water demand and susceptibility to drought stress. To explore the molecular mechanisms underlying response drought, we performed a transcriptome analysis of drought-tolerant -sensitive genotypes under stress, uncovered core drought-responsive genes key signaling pathways. A co-expression network was constructed by weighted gene (WGCNA) candidate hub involved in tolerance were identified. Furthermore, ABA biosynthesis pathways their responses leaves systemically explored. We also found that treatment increased antioxidant enzyme activities glucosinolate contents significantly. These results substantially enhance our understanding cabbage.
