Evidence of regulation of calcium uptake by phytochrome in maize protoplasts

R Das et al. Biochem Biophys Res Commun. .

Abstract

Red light stimulated calcium uptake in maize leaf protoplasts upto 140% over the dark control. The stimulation was maximally noticed after 120 seconds of incubation and was reversed by far red light. 5-Hydroxytryptamine also enhanced calcium uptake in dark, upto the red level. A possible role of phosphoinositide for signal transduction in calcium uptake for phytochrome mediated responses in higher plants is suggested.
