Brassinosteroids (BRs), a class of plant-specific steroidal hormones, play crucial roles in regulating various plant physiological functions, such as growth, development, and adaptability to the environment. Despite this broader role of BRs, previously published reviews mainly focused on the molecular mechanisms of BR-mediated regulation of vegetative and reproductive growth of model plants like and some food crops, such as rice, maize, and wheat. While horticultural plants hold significant economic importance in modern agriculture, less attention has been paid to understanding the role of BRs in regulating the physiological functions of these plants. Given the lack of relevant reviews, this article aims to discuss the major roles of BRs in horticultural plants, particularly fruit and leaf development, whole plant architecture, and adaptive stress response. We also highlight key challenges and provide some future research directions for genetically improving horticultural plants by altering the BR signaling pathway.
油菜素甾醇（BRs）是一类植物特有的甾体激素，在调节植物的各种生理功能中发挥着关键作用，如生长、发育以及对环境的适应性。尽管BRs具有更广泛的作用，但此前发表的综述主要集中在BR介导的模式植物（如拟南芥）以及一些粮食作物（如水稻、玉米和小麦）营养生长和生殖生长调控的分子机制上。虽然园艺植物在现代农业中具有重要的经济价值，但人们对BRs在调节这些植物生理功能方面的作用关注较少。鉴于缺乏相关综述，本文旨在探讨BRs在园艺植物中的主要作用，特别是在果实和叶片发育、整株植物结构以及适应性应激反应方面的作用。我们还强调了关键挑战，并为通过改变BR信号通路对园艺植物进行遗传改良提供了一些未来的研究方向。
