Abstract

Brassinosteroids are a class of sterol hormones essential for plant growth and development. A new study elucidates how uneven cell division in plants regulates brassinosteroid activity, revealing a molecular link between cell polarity and hormone signalling.

摘要

油菜素甾醇是一类对植物生长和发育至关重要的甾醇激素。一项新研究阐明了植物中不均匀的细胞分裂如何调节油菜素甾醇的活性，揭示了细胞极性与激素信号传导之间的分子联系。
