Calcium plays important roles in maintaining plant cellular structure and also acts as a key secondary messenger in intercellular signaling. Thirty years ago, methods of detecting calcium in sub-cellular level had been established (Stockwell and Hanchey, 1982; Borgers et al., 1982) and reviewed extensively (Wick and Heplerm, 1982). We had used the method of testing calcium localization in salt
