Abstract

The calcium-sensing receptor (CAS), as a chloroplast thylakoid membrane protein, is involved in the process of external Ca-induced cytosolic Ca increase in plants. However, the underlying mechanism regulating this process is lacking. Furthermore, recent evidence suggests that CAS may perform additional roles in plants. Here, we provided an update covering the multiple roles of CAS in stomatal movement regulation and Ca signaling in plants. We also analyzed the possible phosphorylation mechanism of CAS by light and discuss the role of CAS in abiotic stress (drought, salt stress) and biotic stresses (plant immune signaling). Finally, we proposed a perspective for future experiments that are required to fill gaps in our understanding of the biological function of CAS in plants.

摘要

钙感知受体（CAS）作为一种叶绿体类囊体膜蛋白，参与植物外部钙诱导的胞质钙增加过程。然而，调节这一过程的潜在机制尚不清楚。此外，最近的证据表明，CAS可能在植物中发挥其他作用。在这里，我们提供了一篇综述，涵盖了CAS在植物气孔运动调节和钙信号传导中的多种作用。我们还分析了光对CAS可能的磷酸化机制，并讨论了CAS在非生物胁迫（干旱、盐胁迫）和生物胁迫（植物免疫信号传导）中的作用。最后，我们提出了未来实验的展望，以填补我们对CAS在植物中生物学功能理解的空白。
