BRI1 — Solanum tuberosum

Summary

PGSC0003DMG400017291, the potato BRI1 gene on chromosome 7, encodes a transmembrane receptor protein serine/threonine kinase with a malectin domain and leucine-rich repeats, classified as EC 2.7.11.1. It exhibits coreceptor activity, steroid binding, SNARE binding, and signaling receptor activity. This gene is associated with immune complex formation, regulation of innate immune response, hormone anabolism, rejection of self pollen, upregulation of reactive oxygen species anabolism, microtubule bundling, megasporogenesis, stomatal complex morphogenesis, detection of molecules of fungal origin, anther wall tapetum development, somatic embryogenesis, skotomorphogenesis, regulation of growth, and regulation of stomatal complex development. It localizes to the plasma membrane, endosome, and macromolecular complexes. Studies of related genes in other species link the family to brassinosteroid signaling and immune responses.
