Salt stress is one of most dramatic abiotic stresses, reduces crop yield significantly. Application of hormones proved effective salt stress ameliorating approach. 24-Epibrassinolide (EBL), an active by-product from brassinolide biosynthesis shows significant salt stress tolerance in plants. EBL application improves plant growth and development under salt stress by playing as signalling compound in different metabolic and physiological processes. This article compiles all identified ways by which EBL improves plant growth and enhances crop yield. Furthermore, EBL enhances photosynthetic rate, reduces ROS production and plays important role in ionic homeostasis. Furthermore EBL-induced salt stress tolerance suggest that complex transcriptional and translational reprogramming occurs in response to EBL and salt stress therefore transcriptional and translational changes in response to EBL application are also discussed in this article.
盐胁迫是最剧烈的非生物胁迫之一,显著降低作物产量。激素的应用被证明是一种有效的缓解盐胁迫的方法。24-表油菜素内酯(EBL)是油菜素内酯生物合成的一种活性副产物,在植物中表现出显著的耐盐胁迫能力。EBL 通过在不同的代谢和生理过程中作为信号化合物的作用,在盐胁迫下改善植物的生长和发育。本文综述了 EBL 改善植物生长和提高作物产量的所有已确定的途径。此外,EBL 提高了光合速率,减少了 ROS 的产生,并在离子稳态中发挥重要作用。此外,EBL 诱导的耐盐胁迫表明,复杂的转录和翻译重编程发生在对 EBL 和盐胁迫的反应中,因此本文还讨论了对 EBL 应用的转录和翻译变化。
