In plant cells, calcium (Ca) serves as a versatile intracellular messenger, participating in several fundamental and important biological processes. Recent studies have shown that the actin cytoskeleton is not only an upstream regulator of Ca signaling, but also a downstream regulator. Ca has been shown to regulates actin dynamics and rearrangements via different mechanisms in plants, and on this basis, the upstream signaling encoded within the Ca transient can be decoded. Moreover, actin dynamics have also been proposed to act as an upstream of Ca, adjust Ca oscillations, and establish cytosolic Ca ([Ca]) gradients in plant cells. In the current review, we focus on the advances in uncovering the relationship between the actin cytoskeleton and calcium in plant cells and summarize our current understanding of this relationship.
在植物细胞中，钙 (Ca) 作为一种多功能的细胞内信使，参与了几个基本的和重要的生物学过程。最近的研究表明，肌动蛋白细胞骨架不仅是 Ca 信号的上游调节剂，也是下游调节剂。已经证明 Ca 通过不同的机制调节植物中的肌动蛋白动力学和重排，在此基础上，可以对 Ca 瞬变中编码的上游信号进行解码。此外，肌动蛋白动力学也被提出作为 Ca 的上游，调节 Ca 振荡，并在植物细胞中建立胞质 Ca([Ca])梯度。在当前的综述中，我们重点介绍了揭示植物细胞中肌动蛋白细胞骨架与钙之间关系的研究进展，并总结了我们对这种关系的理解。
