“…Extracellular purine nucleotides capable of regulating plant development, defense and stress responses by acting in part as agonists of plasma membrane calcium channels. The Purine metabolism is stimulating by ATP release include wounding, osmotic stress and elicitors (Dark et al, 2011).…”

“…Similarly, nitric oxide (NO) can stimulate Ca 2+ fluxes, but it is unknown if this involves direct interaction with putative Ca 2+ channels (Jeandroz et al, 2013). When discussing the interplay of second messengers, it is noteworthy that exogenous L-Glu, used to regulate GLRmediated Ca 2+ flux (Kwaaitaal et al, 2011), can increase extracellular ATP in Arabidopsis (Dark et al, 2011), while extracellular ATP can, in turn, mediate NO accumulation in a phosphatidic acid-dependent manner in tomato (Sueldo et al, 2010). Although analysed in different plants, this signal crosstalk now has to be interpreted in the context of the newly discovered extracellular ATP receptor that mediates a rise in cytosolic Ca 2+ (Choi et al, 2014a).…”

“…Furthermore, eATP is implicated in immunity, abiotic stress responses and nodulation (reviewed by Clark et al ., ; Cho et al ., ). eATP increases in response to wounding, mechanical stimulation, abiotic stress, abscisic acid, glutamate and chitin (Dark et al ., ; Cho et al ., ). eATP can increase plant free Ca 2+ (cytosolic, nuclear, mitochondrial), phosphatidic acid, nitric oxide, and reactive oxygen species (ROS) as potential second messengers in signalling (Demidchik et al ., , ; Loro et al ., ; Cho et al ., ).…”
