Calcium ions function as a key second messenger ion in eukaryotes. Spatially and temporally defined cytoplasmic Ca2+ signals are shaped through the concerted activity of ion channels, exchangers, and pumps in response to diverse stimuli; these signals are then decoded through the activity of Ca2+-binding sensor proteins. In plants, Ca2+ signaling is central to both pattern- and effector-triggered immunity, with the generation of characteristic cytoplasmic Ca2+ elevations in response to potential pathogens being common to both. However, despite their importance, and a long history of scientific interest, the transport proteins that shape Ca2+ signals and their integration remain poorly characterized. Here, we discuss recent work that has both shed light on and deepened the mysteries of Ca2+ signaling in plant immunity.

在真核生物中，钙离子是一个重要的第二信使离子。在响应不同刺激时，通过离子通道、交换和泵的相互协同，形成时空特异性的胞质钙离子信号；接着，这些信号会通过钙结合传感器蛋白进行解码。在植物中，钙离子信号是模式触发免疫PTI和效应子触发免疫ETI的核心，能够响应于两种植物免疫共同的潜在病原体，产生特征性的胞质钙离子升高。然而，尽管钙离子信号具有十分重要的作用，也有着比较深入和久远的研究历史，但是塑造并整合钙离子信号的转运蛋白仍缺乏了解。本文中，作者讨论了最近的一些前沿工作，这些工作揭示并进一步加深了钙离子信号在植物免疫中的奥秘。
