ryanodine/arabidopsis

Cyclic ADP-ribose (cADPR) is a novel second messenger that releases calcium from intracellular stores. Although first shown to release calcium in the sea urchin egg, cADPR has been shown since to be active in a variety of cells and tissues, from plant to human. cADPR stimulates calcium release via

Cyclic ADP ribose (cADPR) is a Ca(2+)-mobilizing intracellular second messenger synthesized from NAD by ADP-ribosyl cyclases (ADPR cyclases). In animals, cADPR targets the ryanodine receptor present in the sarcoplasmic/endoplasmic reticulum to promote Ca(2+) release from intracellular stores to

In Arabidopsis thaliana cell suspension, abscisic acid (ABA) induces changes in cytosolic calcium concentration ([Ca(2+)](cyt)) which are the trigger for ABA-induced plasma membrane anion current activation, H(+)-ATPase inhibition, and subsequent plasma membrane depolarization. In the present study,
