Abstract
Living organisms acquire or synthesize high energy molecules, which they frugally conserve and use to meet their cellular metabolic demands. Therefore, it is surprising that ATP, the most accessible and commonly utilized chemical energy carrier, is actively secreted to the extracellular matrix of cells. It is now becoming clear that in plants this extracellular ATP (eATP) is not wasted, but harnessed at the cell surface to signal across the plasma membrane of the secreting cell and neighboring cells to control gene expression and influence plant development. Identification of the gene/protein networks regulated by eATP-mediated signaling should provide insight into the physiological roles of eATP in plants. By disrupting eATP-mediated signaling, we have identified pathogen defense genes as part of the eATP-regulated gene circuitry, leading us to the discovery that eATP is a negative regulator of pathogen defense in plants.(1) Previously, we reported that eATP is a key signal molecule that modulates programmed cell death in plants.(2) A complex picture is now emerging, in which eATP-mediated signaling cross-talks with signaling mediated by the major plant defense hormone, salicylic acid, in the regulation of pathogen defense and cell death.
