BJUA06G00570S — Brassica juncea

Summary

BjBIN1 (BJUA06G00570S) on Indian mustard chromosome A06 encodes a protein with leucine-rich repeat domains, a BRI1 island domain, and a Ser/Thr/Tyr kinase catalytic domain. The gene is associated with negative regulation of brassinosteroid biosynthesis and activation of brassinosteroid-mediated signaling. It is linked to traits including leaf shattering, shoot growth angle, root hair length, seedling hypocotyl length, water stress tolerance, salt tolerance, and male sterility, as well as phenotypes such as dwarfism and plant architecture. Additional associations include calcium ion homeostasis, amyloplast organization, root system development, phloem development, and anther wall tapetum cell differentiation. The gene product localizes to the plasma membrane, tonoplast, and endosomal compartments. Related genes in other species are associated with pathogen defense, endosomal trafficking, and photomorphogenesis.
