FLS2 — Solanum lycopersicum

Summary

SOLYC10G052880.1, the tomato FLS2 gene on chromosome 10, encodes a transmembrane receptor serine/threonine kinase with leucine-rich repeat domains, possessing protein serine kinase activity, ATP binding, and signaling receptor activity. In tomato, FLS2 is associated with PTI signalling, the MAPK cascade, endocytosis, membrane fission, and immune evasion. It is linked to bacterial disease response, self-incompatibility, and stomatal resistance. The gene product localises to the plasma membrane, endosomes, and extracellular regions. Studies of related genes in other species connect this family to non-self recognition and defence signalling.
