| Abstract: | Recently,the application of recombinant aequorin luminous protein has appeared in measuring calcium signal of plant cell as a new method. This paper introduced mainly the development of the recombinant aequorin luminous protein as a probe,the principle and operates method of measuring calcium concentration,and how to conversion the calcium concentration. It summarized the advantages and deficiencies of the protein,and collected mainly the progress in development studies in measuring calcium signal of plant cell. Meanwhile,using the method provided by other laboratory,the authors got the cold shock kinetics of [Ca2+]cyt and [Ca2+]md for the first time. |
