摘要

Brassinosteroids (BRs) are pivotal endogenous plant hormones recognized for their comprehensive roles in plant growth, development, and fruit ripening. These plant steroid hormones, ubiquitously present across the plant kingdom, are particularly abundant in young tissues, with concentrations differing across plant parts. They are integral in numerous plant processes, from cell proliferation to stress responses. Recent studies have illustrated the role of BRs in fruit ripening, particularly through their interaction with the ethylene biosynthesis pathway. This review summarizes BR biosynthesis, classifying them by carbon number (C-27, C‑28, and C‑29), discussing diverse pathways and their biological significance, and highlighting their impact on fruit ripening, including colour, quality, and ethylene interactions. Notably, the effect of BRs varies across fruit types and is dose-dependent. The application of these findings in agriculture promises potential advancements in optimizing post-harvest quality and fruit shelf life. This review underscores the multifaceted importance of BRs, advocating for deeper research into their precise mechanisms and practical applications.
