BAK1 — Solanum lycopersicum

Summary

SOLYC03G007485.1, the tomato BAK1 gene on chromosome 3, encodes a protein with leucine-rich repeat and protein kinase domains, and is annotated with coreceptor activity, signaling receptor activity, steroid binding, and protein kinase activity. This gene is associated with protein kinase A activation, trans-autophosphorylation, receptor-mediated endocytosis, and upregulation of innate immune response. It has been connected to leaf necrosis, self-incompatibility, and salt tolerance traits. Localization evidence links BAK1 to the plasma membrane, endosome, and macromolecular complexes. 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.
