Abiotic stresses pose significant threat to horticultural crop production worldwide. These stresses adversely affect plant growth, development, and ultimately declined crop growth, yield and quality. In recent years, plant scientists have been actively investigating innovative strategies to enhance abiotic stress resilience in crops, and one promising avenue of research focuses on the use of brassinosteroids (BRs). BRs are a class of plant hormones that play crucial roles in various physiological processes, including cell elongation, differentiation, and stress responses. They have emerged as potent regulators of plant growth and development, and their role in improving abiotic stress tolerance is gaining considerable attention. BRs have been shown to mitigate the negative effects of abiotic stresses by modulating key physiological and biochemical processes, including stomatal regulation, antioxidant defense, osmotic adjustment, and nutrient uptake. Abiotic stresses disrupt numerous physiological functions and lead to undesirable phenotypic traits in plants. The use of BRs as a tool to improve crop resilience offers significant promise for sustainable agriculture in the face of increasing abiotic stresses caused by climate change. By unraveling the phenomenon of BRs, this review emphasizes the potential of BRs as an innovative approach for boosting abiotic stress tolerance and improving the overall productivity and quality of horticultural crops. Further research and field trials are necessary to fully harness the benefits of BRs and translate these findings into practical applications for crop production systems.
非生物胁迫对全球园艺作物生产构成重大威胁。这些胁迫会对植物生长、发育产生不利影响，并最终导致作物生长、产量和品质下降。近年来，植物科学家一直在积极研究提高作物非生物胁迫抗性的创新策略，其中一个有前景的研究方向聚焦于油菜素甾醇（BRs）的应用。BRs是一类植物激素，在包括细胞伸长、分化和胁迫响应等各种生理过程中发挥关键作用。它们已成为植物生长和发育的有力调节因子，其在提高非生物胁迫耐受性方面的作用正受到广泛关注。研究表明，BRs可通过调节关键生理和生化过程来减轻非生物胁迫的负面影响，这些过程包括气孔调节、抗氧化防御、渗透调节和养分吸收。非生物胁迫会破坏众多生理功能，并导致植物出现不良表型特征。面对气候变化导致的非生物胁迫不断增加，将BRs用作提高作物抗性的工具，为可持续农业带来了巨大希望。通过深入研究BRs这一现象，本综述强调了BRs作为一种创新方法在增强非生物胁迫耐受性以及提高园艺作物整体生产力和品质方面的潜力。要充分利用BRs的益处并将这些研究结果转化为作物生产系统的实际应用，还需要进一步的研究和田间试验。
