INTRODUCTION ATP is present in high concentrations within the cell (~mM) but is typically found at much lower levels (~nM) in the extracellular space, where it functions as a potent signaling molecule essential for cellular communication (Watt et al., 1998; Weerasinghe et al., 2009). This purinergic signaling is well-documented across eukaryotic systems (Burnstock & Verkhratsky, 2009).

Abstract Extracellular ATP (eATP) signaling in Arabidopsis thaliana is mediated by the purinoceptor P2K1. Previous studies have clarified that the downstream transcriptional responses to eATP involve jasmonate (JA)-based signaling components such as the JA receptor (COI1) and JA-responsive bHLH transcription factors (MYCs). However, the specific contributions of JA signaling itself on eATP signaling are unexplored. Here, we report that JA primes plant responses to eATP through P2K1.
