Abstract

SummaryCotton cultivation spans over 30 million hectares across 85 countries and regions, with more than half participating in the global cotton textile trade. The elongated cotton fiber cell is an ideal model for studying cell elongation and understanding plant growth and development. Brassinosteroids (BRs), recognized for their role in cell elongation, offer the potential for improving cotton fiber quality and yield. Despite extensive research highlighting BR's positive impact on fiber development, a comprehensive review on this topic has been lacking. This review addresses this gap, providing a detailed analysis of the latest advancements in BR signaling and its effects on cotton fiber development. We explore the complex network of BR biosynthesis components, signaling molecules, and regulators, including crosstalk with other pathways and transcriptional control mechanisms. Additionally, we propose molecular strategies and highlight key genetic elements for optimizing BR‐related genes to enhance fiber quality and yield. The review emphasizes the importance of BR homeostasis and the hormonal landscape during cotton fiber development, offering insights into targeted manipulation opportunities and challenges. This consolidation offers a comprehensive understanding of BR's multifaceted roles in fiber development, outlining a strategic approach for BR optimization in cotton fiber quality and yield.

棉花中的芸苔素类固醇：协调纤维发育

摘要棉花种植面积超过 3,000 万公顷，遍布 85 个国家和地区，其中一半以上参与全球棉纺织品贸易。伸长的棉花纤维细胞是研究细胞伸长和了解植物生长发育的理想模型。芸苔素类固醇（BRs）因其在细胞伸长中的作用而得到公认，具有提高棉纤维质量和产量的潜力。尽管大量研究强调了芸苔素甾类化合物对纤维发育的积极影响，但一直缺乏有关这一主题的全面综述。本综述弥补了这一空白，详细分析了BR信号转导的最新进展及其对棉纤维发育的影响。我们探讨了 BR 生物合成成分、信号分子和调控因子的复杂网络，包括与其他途径和转录控制机制的串扰。此外，我们还提出了分子策略，并强调了优化 BR 相关基因以提高纤维质量和产量的关键遗传要素。综述强调了棉纤维发育过程中BR平衡和荷尔蒙状况的重要性，为有针对性的操作提供了机遇和挑战。本综述全面介绍了BR在纤维发育过程中的多方面作用，概述了在棉花纤维质量和产量方面优化BR的战略方法。
