Abstract
Plant sterols and steroid hormones, the brassinosteroids (BRs), are compounds that exert a wide range of biological activities. They are essential for plant growth, reproduction, and responses to various abiotic and biotic stresses. Given the importance of sterols and BRs in these processes, engineering their biosynthetic and signaling pathways offers exciting potentials for enhancing crop yield. In this review, we focus on how alterations in components of sterol and BR metabolism and signaling or application of exogenous steroids and steroid inhibitors affect traits of agronomic importance. We also discuss areas for future research and identify the fine-tuning modulation of endogenous BR content as a promising strategy for crop improvement.
摘要
植物固醇和甾体激素，如油菜素甾醇（BRs），是具有广泛生物活性的化合物。它们对植物的生长、繁殖以及对各种非生物和生物胁迫的响应至关重要。鉴于固醇和 BR 在这些过程中的重要性，对其生物合成和信号途径进行工程改造为提高作物产量提供了令人兴奋的潜力。在这篇综述中，我们重点讨论了固醇和 BR 代谢和信号转导成分的改变或外源甾体和甾体抑制剂的应用如何影响农业重要性状。我们还讨论了未来的研究领域，并确定了精细调节内源性 BR 含量作为作物改良的有前途的策略。
