P2K1 — Arabidopsis thaliana

Summary

AT5G60300 (P2K1, DORN1) in Arabidopsis thaliana encodes a non-specific serine/threonine protein kinase with ATP-binding and sugar-binding activities, belonging to the L-type lectin receptor kinase family. It is localized to the plasma membrane. P2K1 is associated with extracellular ATP signaling, cellular response to ATP, and the MAPK cascade. It is linked to stomatal closure, defense response to oomycetes, regulation of jasmonic acid-mediated signaling, and cell adhesion. The gene is associated with calcium signaling, innate immunity, disease resistance, resistance to Pseudomonas syringae and Rhizoctonia solani, salt stress resistance, and wound response. Additionally, P2K1 is associated with root growth, pollen tube development, seed germination, and traits such as abscisic acid content, jasmonic acid content, and root length.
