Plant growth relies on interconnected hormonal pathways, their corresponding transcriptional networks and mechanical signals. This work reviews recent brassinosteroid (BR) studies and integrates them with current growth models derived from research in roots. The relevance of spatiotemporal BR signaling in the longitudinal and radial root axes and its multifaceted interaction with auxin, the impact of BR on final cell size determination and its interplay with microtubules and the cell wall are discussed. Also highlighted are emerging variations of canonical BR signaling that could function in developmental-specific context.

从油菜素类固醇的角度来看增长模型。

植物生长依赖于相互连接的激素途径，其相应的转录网络和机械信号。这项工作回顾了最近的油菜素类固醇（BR）研究，并将其与根源研究得出的当前生长模型相结合。讨论了时空BR信号在纵向和径向根轴上的相关性及其与生长素的多方面相互作用，BR对最终细胞大小确定的影响及其与微管和细胞壁的相互作用。还强调了可以在特定于发展的情况下发挥作用的规范BR信号的新兴变化。
