FLS2 — Solanum lycopersicum

Summary

SlFLS2 (SOLYC02G031790.3) on tomato chromosome 2 encodes a transmembrane receptor protein serine/threonine kinase with leucine-rich repeat domains. It is associated with activation of immune response, MAPK cascade, and PTI signalling. The gene has been connected to bacterial disease response, stomatal resistance, and self-incompatibility. Its product localizes to the plasma membrane, extracellular region, and endoplasmic reticulum. Related genes in other species include FLS2 and XA21. Additional associations include membrane fission, protein secretion, chemotaxis, and biofilm formation.
