BAK1 — Solanum lycopersicum

Summary

SOLYC12G056300.3, the tomato BAK1 gene on chromosome 12, encodes a transmembrane receptor serine/threonine kinase with coreceptor activity, protein kinase activity, and ATP binding, featuring leucine-rich repeat and kinase domains. In tomato, BAK1 is associated with protein kinase A activation, trans-autophosphorylation, receptor-mediated endocytosis, actin polymerization, sexual reproduction, organ growth, floral organ development, and response to AOS. It localizes to the membrane, plasmalemma, and nucleus. The gene is linked to leaf necrosis, self-incompatibility, and salt tolerance. Studies of related genes in other species connect the BAK1 family to plant height and stem elongation, though these associations are not yet established in tomato.
