BRI1 — Solanum tuberosum

Summary

PGSC0003DMG400015666, the potato BRI1 gene on chromosome 11, encodes a leucine-rich repeat receptor-like kinase with transmembrane receptor protein serine/threonine kinase activity, protein kinase activity, and steroid binding capacity. It is associated with detection of brassinosteroid stimulus, hormone-mediated signaling, regulation of growth and cell growth, stomatal complex morphogenesis and development, pollen maturation, somatic embryogenesis, skotomorphogenesis, post-embryonic plant organ development, immune complex formation, upregulation of innate immune response, regulation of defence response to fungi, virus-induced PTGS, response to salt, and upregulation of response to thirst. The product localizes to the plasma membrane, endosome, cytoplasm, pollen tube, and intracellular membrane-bounded organelles. Studies of related genes in other species link this family to brassinosteroid perception and plant development.
