FLS2 — Solanum lycopersicum

Summary

SlFLS2 (SOLYC03G025960.1) on tomato chromosome 3 encodes a transmembrane receptor protein with serine/threonine kinase binding, signaling receptor activity, and calmodulin binding, among other molecular functions. It is associated with activation of immune response, upregulation of systemic acquired resistance, upregulation of defense response to oomycetes, and cellular response to salicylate stimulus. The gene is linked to bacterial blight disease resistance, bacterial disease response, aphid response trait, and biotic plant stress trait. Associations also include drought stress tolerance, ABA signaling, increased heat and cold tolerance, photosynthesis, and effector-triggered immunity. Additional connections involve leaf chlorophyll content, spikelet fertility, biomass yield, root hair length, days to flowering trait, stomatal resistance, and high temperature stress response. Studies of related genes in other species link the family to flagellin perception, broad-spectrum disease resistance, and bacterial pathogen immunity.
