SWEET (Sugar Will Eventually be Exported Transporter) proteins play vital roles in the transport of sugars, contributing to regulation plant development, hormone signaling, and responses abiotic stress. In this study, we identified 57 NtSWEETs tobacco (Nicotiana tabacum L.), then their physicochemical properties, chromosomal localization, synteny, phylogenetic relationships, genomic structure, promoter cis-elements, protein interaction network, tissue specificity, expression pattern were systematically analyzed. addition, NtSWEET12i improves drought saline-alkali tolerance by enhancing soluble sugars transport, ABA proline biosynthesis, ROS scavenging. These findings illuminate role NtSWEETs, particularly NtSWEET12i, regulating stresses. This study offers new insights enhance our understanding identify potential genes involved plants.

The homeostasis of the proline-Δ1-pyrroline-5-carboxylate (Pro-P5C) cycle, mediated by proline dehydrogenase (ProDH), plays a critical role in plants response to abiotic stresses. biological function gene CsProDH1 under drought stress and its effects on amino acid metabolism photosynthesis through were investigated. Enzymatic characterization protein was conducted vitro. Overexpression aggravated plant stress, as evident reduced photosynthetic efficiency increased reactive oxygen species, which activated Pro-P5C cycle. In contrast, silencing enhanced resistance, accumulation, protected photosynthesis. Studies indicate that exogenous application mitigates drought-induced physiological impairments maintaining cellular homeostasis, with particular efficacy observed enhancing tea resilience improved osmotic adjustment antioxidant capacity. This study uncovers significant resistance regulatory mechanism, offering potential targets strategies for crop resistance.

Abstract Melatonin has emerged as a potent plant growth regulator, significantly enhancing the postharvest quality of horticultural products. Structurally analogous to hormone indole-3-acetic acid, it regulates key processes like seed germination, growth, flowering and defense against abiotic stresses. Its powerful antioxidant properties make an effective free radical scavenger, boosting resilience oxidative stress positioning innovative phytohormone for treatments. The current study explores efficacy melatonin in delaying senescence detached scapes Hemerocallis fulva. Scapes were harvested when most mature bud was one day before anthesis treated with different concentrations (40, 80, 120, 160 µM). Results indicate that 120 µM treatment delayed senescence, extending vase life flower (12 days) relative untreated controls (7 days), which showed accelerated senescence. application associated enhanced enzyme activity, reduced lipoxygenase activity diminished hydrogen peroxide (H2O2) levels, collectively alleviating stress. Furthermore, content soluble proteins, phenols, sugar fractions proline within tepal tissues. also effectively suppressed bacterial proliferation improved solution uptake scapes. These findings suggest modulates H. fulva by orchestrating responses quality, offering holistic approach management.
