Abstract
Evidence for spatial variations in cytoplasmic free Ca2+ in tip-growing cells is briefly summarized. Methods are described for detecting such gradients using fura-2 with dual wavelength excitation fluorescence microscopy. Results so far indicate that gradients of Ca2+ are present in growing rhizoid cells but physiologically significant gradients have not yet been detected in the early stages of polarization.Keywords
