CC -!- FUNCTION: Regulates the brassinosteroid (BR) signaling pathway that
CC mediates cell elongation and organ morphogenesis (PubMed:19202280).
CC {ECO:0000269|PubMed:19202280}.
CC -!- FUNCTION: (Microbial infection) Facilitates the development of the
CC powdery mildew fungus E.cruciferarum. {ECO:0000269|PubMed:23888068}.
CC -!- FUNCTION: (Microbial infection) May prevent cell death upon A.alternata
CC f.sp. lycopersici (AAL) toxin treatment. {ECO:0000269|PubMed:23888068}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Multi-pass membrane
CC protein {ECO:0000255}.
CC -!- TISSUE SPECIFICITY: Expressed in seedlings, roots, leaves,
CC inflorescences and flowers. {ECO:0000269|PubMed:19202280,
CC ECO:0000269|PubMed:23888068}.
CC -!- INDUCTION: Repressed by Brz, a triazole compound that acts as a
CC brassinosteroid (BR)-specific inhibitor. {ECO:0000269|PubMed:19202280}.
CC -!- DISRUPTION PHENOTYPE: Delayed development of the powdery mildew fungus
CC E.cruciferarum. Increased cell death upon A.alternata f.sp. lycopersici
CC (AAL) toxin treatment. {ECO:0000269|PubMed:23888068}.
CC -!- SIMILARITY: Belongs to the BI1 family. {ECO:0000305}.
