Cyclic ADP-ribose (cADPR) is one of many possible components that could be used in cellular signal transduction mechanisms. Wu et al. (p. 2126; see the news story by Pennisi, p. 2054) provide evidence that the physiological response of plants to the hormone abscisic acid is mediated through cADPR and calcium. Abscisic acid regulates higher plant responses to a great variety of stresses, including drought and cold.
