Brassinosteroid （BR） signaling, plant innate immunity, and stomatal developments are three pathways that are initiated by receptor-like kinases. This commentary focuses on the lat- est findings in the role of BR signaling in plant immunity and stomatal development that provide some insight into the molecular mechanism of the BR signal pathway interacting with other receptor signaling pathways.

Light is the energy source for plant photosynthesis and influences plant growth and *** multiple photoreceptors, plant interprets light signals through various downstream phytohormones such as auxin. Recently, Chen et al.(2020) uncover a new layer of regulation in IPyA pathway of auxin biosynthesis by light. Here we highlight recent studies about how light controls plant growth through regulating auxin biosynthesis and signaling.

生长素在植物生长发育过程中发挥重要作用,其信号转导机制一直是植物学领域关注的热点。前期研究表明,ABP1-TMK分子模块参与胞外生长素信号感受,但ABP1作为生长素受体备受争议。近期,福建农林大学徐通达团队和杨贞标团队鉴定到ABL蛋白作为生长素结合蛋白参与胞外生长素信号感受。与传统的功能冗余不同,ABL和ABP1通过蛋白结构的相似性实现功能补偿效应,进而与TMK在细胞膜上形成复合体,作为胞外生长素的共受体介导生长素信号驱动的快速反应。该研究深入解析了胞外生长素信号感受的重要机制,是生长素研究领域的重大突破。
