Abstract excerpt
Plants have circadian oscillations in the concentration of cytosolic free calcium ([Ca(2+)](cyt)). To dissect the circadian Ca(2+)-signaling network, we monitored circadian [Ca(2+)](cyt) oscillations under various light/dark conditions (including different spectra) in Arabidopsis thaliana wild type and photoreceptor and circadian clock mutants. Both red and blue light regulate circadian oscillations of...
