These stresses also weaken plant defense capacity, indirectly increasing vulnerability to pests and diseases and challenging the effectiveness of integrated disease management (IDM) systems. Recent advances identify nanoparticles (NPs) as an innovative and signaling regulator tool for enhancing abiotic stress tolerance in oil crops through coordinated physiological and molecular regulation. The present review synthesizes current knowledge on NPs applications in major oil-bearing crops, with emphasis on drought, salinity, heavy metal toxicity and temperature extremes. A key innovation is the integration of NPs application strategies with crop-specific physiological traits, molecular responses, and hormonal and redox signaling networks. We highlight new insights showing that NPs act as active regulators of stress adaptation by stabilizing membranes, maintaining redox homeostasis, activating antioxidant defenses, modulating stress-responsive gene expression, and interacting with phytohormones and nitric oxide (NO) signaling. By adopting a cross-crop, cross-stress framework, the present review moves beyond stress- or species-specific analyses and directly links abiotic stress mitigation to improved plant resilience and IDM robustness. Key research gaps, including limited field validation, uncertainties in optimal dosing and delivery, and insufficient understanding of environmental fate and safety, are identified.

In this study, exogenous Tre, IAA, and gibberellin (GA) significantly promoted stem internode cell expansion and elongation and increased plant biomass in melon seedlings. Inhibition of IAA signaling by N-1-naphthylphthalamic acid (NPA), an inhibitor of polar auxin transport, attenuated the effect of Tre but did not affect the effect of GA.

These findings indicate that Tre promotes melon seedling growth under normal temperature conditions and after recovery from low-temperature stress by mediating IAA and GA signaling. Crosstalk occurs between the IAA and GA pathways, and GA may act downstream of IAA as a central component of Tre function. CmSAUR1 may integrate the interaction between GA and IAA signaling and participate in Tre-mediated growth regulation.

It is widely used in animal husbandry and ecological protection. However, soil salinization has become a major environmental factor limiting its yield and quality. In this study, two alfalfa cultivars, Zhongmu No. 1 (ZM) and SK3010 (SK), were subjected to saline-alkali stress. The treatment resulted in stunted growth, leaf chlorosis, and cell membrane damage. Compared with SK, ZM exhibited less damage and stronger saline-alkali tolerance. Transcriptomic analysis revealed that the proportion of up-regulated differentially expressed mRNAs (DEMs) in ZM was significantly higher than in SK. The antioxidant systems and plant hormone signal transduction pathways are central to saline-alkali stress adaptation. Integrated transcriptome and small RNA sequencing identified 59 saline-alkali stress-responsive differentially expressed microRNAs (DEMIs) that target 119 DEMs. Functional analysis demonstrated that the phenylpropanoid biosynthesis and the starch and sucrose metabolism pathways are critical for stress response. These results indicated that alfalfa mitigates saline-alkali stress through the regulation of the antioxidant system, hormone biosynthesis and signaling, phenylpropanoid biosynthesis, and the hydrolysis of starch to soluble sugars. In particular, ZM exhibited greater tolerance by accumulating fewer reactive oxygen species while elevating antioxidant enzyme activity and antioxidant content and enhancing lignin and sucrose biosynthesis.

After 21 days of stress, exposure to heat alone induced distinct physiological adjustments, including increased stomatal conductance, transpiration and net CO<sub>2</sub> assimilation, as well as changes in mineral composition. Conversely, drought alone or in combination with heat, impaired plant growth, inducing clear signs of oxidative damage and redox imbalance. This was accompanied by negative impacts on photosynthesis, including reduced gas exchange and dysregulation of photochemical processes. In addition, parameters related to nitrogen and carbon metabolism were also affected under drought, as evidenced by reduced levels of nitrate, ammonium and amino acids, downregulation of glutamine synthetase activity and increased sugar accumulation. Notably, water scarcity also led to oxidative damage. Finally, both drought and heat influenced potassium and calcium accumulation in leaves. Overall, our findings support that drought is the primary driver of physiological impairment in chestnut, while heat employs significant but distinct effects and modulates plant responses under combined stress.
