Extracellular ATP signaling in plants.
Extracellular adenosine-5'-triphosphate (ATP) induces a number of cellular responses in plants and animals. Some of the molecular components for purinergic signaling in animal cells appear to be lacking in plant cells, although some cellular responses are similar in both systems [e.g. increased levels of cytosolic free calcium, nitric oxide (NO), and reactive oxygen species (ROS)]. The purpose ...
متن کاملIs ATP a signaling agent in plants?
Physiological processes in plant cells are regulated by intrinsic and extrinsic signals. Numerous signaling molecules have been identified, including hormones, elicitors, and secondary metabolites. Cognate receptors and receptor genes have been reported in some cases (Hua and Meyerowitz, 1998; Inoue et al., 2001; Nam and Li, 2002). Several second messengers (responsible for signal amplification...
متن کاملExtracellular ATP in plants. Visualization, localization, and analysis of physiological significance in growth and signaling.
Extracellular ATP (eATP) in animals is well documented and known to play an important role in cellular signaling (e.g. at the nerve synapse). The existence of eATP has been postulated in plants; however, there is no definitive experimental evidence for its presence or an explanation as to how such a polar molecule could exit the plant cell and what physiological role it may play in plant growth...

متن کاملExtracellular ATP signaling via P2X(4) receptor and cAMP/PKA signaling mediate ATP oscillations essential for prechondrogenic condensation.
Prechondrogenic condensation is the most critical process in skeletal patterning. A previous study demonstrated that ATP oscillations driven by Ca(2+) oscillations play a critical role in prechondrogenic condensation by inducing oscillatory secretion. However, it remains unknown what mechanisms initiate the Ca(2+)-driven ATP oscillations, mediate the link between Ca(2+) and ATP oscillations, an...
