BIN1 — Lactuca sativa

Summary

LsBIN1, also known as LsBRI1, encodes a protein with a leucine-rich repeat domain, a Ser/Thr kinase domain, and multiple annotated molecular functions including transmembrane receptor protein tyrosine kinase activity, protein kinase inhibitor activity, and signaling receptor binding activity. It is associated with negative regulation of brassinosteroid biosynthetic process, regulation of growth by external signal, root system development, regulation of seedling development, phloem development, and negative gravitropism. The gene is linked to stem length, shoot growth angle, leaf growth and development, plant male sterility, water and temperature stress response traits, aphid and insect damage response traits, phosphorus and nitrate uptake, and auxin and brassinosteroid content. Studies of related genes in other species connect the family to yield, fruit traits, photosynthetic ability, and stress tolerance.
