摘要
Ca2+作为第二信使参与了植物生长和发育过程的调控,不同生物和非生物胁迫信号均可诱导胞内Ca2+变化。对Ca2+在信号转导作用中的认识主要来自于细胞内Ca2+浓度测定。水母发光蛋白和基于荧光蛋白的Ca2+荧光指示剂作为检测细胞Ca2+信号的手段是近年发展起来的新方法。本文综述了水母发光蛋白和基于荧光蛋白的Ca2+荧光指示剂的发展、测量原理、优点与不足及其在细胞Ca2+信号转导中的应用研究进展。
Accumulating evidence suggests that Ca2+ serves as a messenger in many normal growth and developmental process and in plant responses to biotic and abiotic stresses.Assessment of the role of Ca2+ in signal transduction requires knowledge of its intracellular levels.As new calibration Ca2+ methods aequorin and fluorescent protein based Ca2+ indicators were developed in the recent years.In this review we show the development of Ca2+ fluorescent probes,the mechanisms of measuring Ca2+,advantages and disadvantages of aequorin,fluorescent protein based Ca2+ probes.We also show the progress in cellular Ca2+ signal research.
