The use of gibberellin-related dwarfing genes significantly increased grain yield during the Green Revolution. Brassinosteroids (BRs) play a vital role in regulating agronomic traits and stress resistance. The potential of BR-related genes in crop improvement has been well demonstrated, positioning BRs as crucial targets for the next agricultural biotechnological revolution. However, BRs exert pleiotropic effects on plants, and thus present both opportunities and challenges for their application. Recent research suggests promising strategies for leveraging BR regulatory molecules for crop improvement, such as exploring function-specific genes, identifying beneficial alleles, inducing favorable mutations, and optimizing spatial hormone distribution. Advancing our understanding of the roles of BRs in plants is imperative to implement these strategies effectively.
在绿色革命期间，使用赤霉素相关矮化基因显著提高了粮食产量。油菜素内酯（BRs）在调节农艺性状和抗逆性方面发挥着重要作用。BR 相关基因在作物改良中的潜力已经得到充分证明，将 BRs 定位为下一次农业生物技术革命的关键目标。然而，BRs 对植物具有多效性作用，因此在应用方面既存在机遇，也存在挑战。最近的研究提出了利用 BR 调节分子进行作物改良的有前景的策略，例如探索功能特异基因、鉴定有利等位基因、诱导有利突变和优化空间激素分布。深入了解 BR 在植物中的作用对于有效实施这些策略至关重要。
