| Abstract: | External ATP stimulated stomatal opening in epidemal strips of Commelina communis L. in darkness following brief irradiation with white or red light. ATP had no effect in darkness after irradiation with far red light or in continuous light. Mg2+ stimulated stomatal response to ATP, which was shown to be taken-up by the tissue. This implies that a Mg-stimulated ATPase, that interacts with Pfr, may be involved in stomatal opening. |
