Brassinosteroids (BRs) are widely used class of natural steroidal plant hormones. BRs take part in the regulation of growth and development of plants, maintaining BRs homeostasis, and allowing adaptation to environmental changes through the life cycle. They also play an important role in abiotic stress responses such as drought, salinity, high temperature, low temperature and heavy metal stresses. Through the signal transduction pathway, BRs interact with a variety of transcription factors via a series of phosphorylation cascades to regulate the expression of BR target genes. Thus, they regulate the various growth and development processes of plants. BRs crosstalk with different hormones to regulate plant physiology and development. This review primarily introduces the signaling pathways of BRs, their role in regulating plant growth and development, abiotic stresses, and their interaction with other plant hormones at the transcriptional and post-transcriptional levels. Our review of this topic will provide a complete reference for the study and utilization of BRs in the future.

油菜素类固醇在植物生长和非生物胁迫反应中的作用

油菜素类固醇 (BRs) 是广泛使用的一类天然甾体植物激素。BRs 参与植物生长和发育的调节，维持 BRs 的稳态，并允许在整个生命周期中适应环境变化。它们还在干旱、盐分、高温、低温和重金属胁迫等非生物胁迫响应中发挥重要作用。通过信号转导途径，BRs通过一系列磷酸化级联反应与多种转录因子相互作用，从而调节BR靶基因的表达。因此，它们调节植物的各种生长和发育过程。BRs 与不同的激素相互作用以调节植物生理和发育。本综述主要介绍了 BRs 的信号通路，它们在调节植物生长和发育、非生物胁迫中的作用，以及它们在转录和转录后水平与其他植物激素的相互作用。我们对这一课题的综述将为今后BRs的研究和利用提供完整的参考。
