SERK1 — Arabidopsis thaliana

Summary

AT1G71830 (SERK1) in Arabidopsis thaliana encodes a transmembrane receptor protein serine/threonine kinase with leucine-rich repeat domains, classified as EC 2.7.10.1. The gene is associated with embryogenesis, receptor internalization, cell dedifferentiation, anti-apoptosis, immune response-regulating signaling, meristem cell homeostasis, pollen hydration, and negative regulation of seed maturation and floral organ abscission. It has been linked to traits including grain yield, brassinosteroid content, bacterial blight disease resistance, viral disease response, fruit ripening, lignin biosynthesis, temperature stress response, and leaf rolling. Localization evidence connects SERK1 to the heterotrimeric G-protein complex, nuclear envelope, spindle, and ribosome. Studies of related genes in other species link the family to anther cell fate determination, male sterility, tapetum development, and fungal pathogen resistance.
