β¦ Synopsis
Analysis of the light-induced changes of cytosolic Ca2+ ([Ca2+]i) in photoreceptor cells has been taken a step further with two recently published studies. In one, changes in [Ca2+]i were measured in single detached rod outer segments from Gecko in response to various light intensities. The advances of the other are embodied in its employment of transgenic Drosophila, whose photoreceptors express a visual pigment that is insensitive to the wavelength of light used in the fluorescence imaging of [Ca2+]i. These studies provide a better basis for understanding the regulation of Ca(2+)-mediated events in photoreceptor cells.

The hypothesis that increases in cytosolic free calcium ([Ca^2+^]~i~) are a component of the CO~2~ signal transduction pathway in stomatal guard cells of __Commelina communis__ has been investigated. This hypothesis was tested using furaβ2 fluorescence ratio photometry to measure changes in guard ce
The typical fungal membrane component ergosterol was previously shown to trigger defence responses and protect plants against pathogens. Most of the elicitors mobilize the second messenger calcium, to trigger plant defences. We checked the involvement of calcium in response to ergosterol using Nicot
