虽然胞质钙 (Ca2+) 作为第二信使在众多信号通路中发挥着核心作用,但胞质钙的动态变化如何与细胞生长控制相关仍然知之甚少。基因编码钙传感器(例如 Yellow Cameleon (YC) 传感器)的工程设计和不断改进与显微镜技术的进步相结合,可以对胞质 [Ca2+] 细胞素单个细胞的时空特征进行高分辨率成像。因此,一个令人兴奋的新步骤包括仔细研究突变背景中的钙动力学,这些突变背景显示出细胞生长行为受到干扰,以进一步增强我们对生长相关过程的理解。在这里,我们描述了使用共焦激光扫描显微镜在稳定表达 YC3.6 的生长拟南芥野生型和 NADPH 氧化酶缺陷 rbohH rbohJ 花粉管中进行 [Ca2+] 细胞动力学成像的方法。我们还提出了不同的方法来提取有关生长过程中钙动态的有意义的定性和定量信息。
While cytosolic calcium (Ca2+) plays a central role in a myriad of signaling pathways as a secondary messenger, how dynamic changes of cytosolic calcium relate to cell growth control remains poorly understood. The engineering and continuous improvements of genetically encoded calcium sensors such as the Yellow Cameleon (YC) sensors combined with advances in microscopy have allowed imaging with great resolution of the spatiotemporal characteristics of cytosolic [Ca2+]cytin individual cells. An exciting new step consists therefore in cautiously studying calcium dynamics in mutant backgrounds that display disturbed cellular growth behavior to further enhance our understanding on growth-related processes. Here, we describe methods to perform imaging of [Ca2+]cytdynamics in growingArabidopsis thalianawild-type and NADPH-oxidase deficientrbohH rbohJpollen tubes stably expressing YC3.6 using confocal laser scanning microscopy. We also present different ways to extract meaningful qualitative and quantitative information about calcium dynamics during growth.
