[Abstract] Cytoplasmic calcium ([Ca2+]cyt) acts as a stimulus-induced second messenger in multiple signal transduction cascades (Allen et al., 1999). In plant cells, a dramatic and readily assayed response to stimulus is the change of stomatal aperture. Changes in [Ca2+]cyt of stomatal guard cells were involved in stomatal movement in response to various stimuli and cellular processes. In general, there are two available ways to measure [Ca2+]cyt in guard cells, i.e., loading of calcium-sensitive fluorescence dyes such as fluo-3 AM and fura-2 or expressing genetically encoded calcium indicators such as yellow cameleon (Krebs et al., 2012). In this protocol, we aim at describing the experimental procedure to ...
[摘要] 细胞质钙（[Ca 2+] + cyt）在多个信号转导级联中用作刺激诱导的第二信使（Allen等人， 1999）。在植物细胞中，对刺激的戏剧性和容易测定的响应是气孔孔径的变化。气孔保卫细胞的[Ca + ] 细胞的变化参与响应于各种刺激和细胞过程的气孔运动。一般来说，有两种可用的方法来测量保护细胞中的钙离子荧光染料的加载量，即 例如fluo-3AM和fura-2或表达遗传编码的钙指示剂例如黄色卡梅伦（Krebs等人，2012）。在该方案中，我们旨在描述在ABA或PA处理时加载fluo-3AM的保卫细胞中记录[Ca 2 cyT 用共聚焦激光扫描显微镜进行荧光成像。
