Abstract The postharvest lifespan of horticultural products is closely related to loss nutritional quality, accompanied by a rapid decline in shelf life, commercial value, and marketability. Melatonin (MT) application not only maintains quality but also delays senescence products. This paper reviews biosynthesis metabolism endogenous MT, summarizes significant effects exogenous MT on products, examines regulatory mechanisms MT‐mediated effects, provides an integrated review for understanding the positive role delay maintenance. As multifunctional molecule, coordinates other signal molecules, such as ABA, ETH, JA, SA, NO, Ca 2+ , regulate ripening senescence. Several metabolic pathways are involved regulation during senescence, including synthesis transduction plant hormones, redox homeostasis, energy metabolism, carbohydrate degradation pigment cell wall components. Moreover, regulates expression genes antioxidant systems, generation, fruit firmness colour, membrane integrity, storage. Consequently, could become emerging eco‐friendly preservative extend life maintain

Understanding drought resistance mechanisms is crucial for breeding poplar species suited to arid and semiarid regions. This study explored the responses of three newly developed 'Zhongxiong' series poplars using integrated transcriptomic physiological analyses. Under stress, leaves showed significant changes in differentially expressed genes linked photosynthesis-related pathways, including photosynthesis-antenna proteins carbon fixation, indicating impaired photosynthetic function assimilation. Additionally, stress triggered oxidative damage through increased reactive oxygen production, leading malondialdehyde accumulation. Weighted gene co-expression network analysis revealed that closely associated with were enriched cell redox homeostasis specifically thioredoxin-peroxiredoxin pathway. Key this pathway cyclic electron flow, such as PGR5-L1A, downregulated, suggesting compromised scavenging photoprotection under stress. Notably, ZX4 exhibited higher tolerance, maintaining stronger activity flow compared ZX3 ZX5. Genes like 2-Cys Prx BAS1, PrxQ TPX are promising candidates enhancing genetic improvement, potential applications developing resilient forestry varieties.

Salt stress is a significant environmental factor that impedes maize growth and yield. Exogenous 5-aminolevulinic acid (ALA) has been shown to mitigate the detrimental effects of various stresses on plants. However, its regulatory role in photosynthesis mechanisms seedlings under salt remains poorly understood. Transcriptome sequencing physiological index measurements were conducted leaves “Zhengdan 958” cultivar subjected three different treatments. Differential expression analysis revealed 4634 differentially expressed genes (DEGs), including key transcription (TF) families such as NAC, MYB, WRKY, MYB-related, across two comparisons (SS_vs_CK ALA_SS_vs_SS). Significant enrichment was observed metabolic pathways related porphyrin metabolism, photosynthesis-antenna proteins, photosynthesis, carbon fixation photosynthetic organisms. ALA treatment modulated photosynthesis-related genes, increased pigment content, enhanced activities superoxide dismutase (SOD) catalase (CAT), thereby mitigating excessive accumulation reactive oxygen species (ROS). Furthermore, starch content stress. These findings establish foundational understanding molecular through which regulates seedlings. Collectively, exogenous enhances maize’s tolerance by regulating pathways.
