Abstract:
As an important signaling molecule, eATP (extracellular ATP) triggers a series of cellular responses by binding to plasma membrane receptors and subsequently stimulates the production of second messengers such as calcium ions. DORN1 is identified as the first plant eATP receptor and can mediate eATP signaling to participate in many physiological processes in plants, including disease resistance, stomatal opening and closing, as well as the endocytosis cycle. This review summarizes the researches on discovery, structure and functions of DORN1, and gives some prospects for the future studies of DORN1.
