FLS2 — Solanum lycopersicum

Summary

SOLYC05G026240.3, also known as SlLRX3 or FLS2, encodes a transmembrane receptor serine/threonine kinase with leucine-rich repeat (LRR) domains and steroid, SNARE, and ATP binding activities. In tomato, this gene is associated with immune evasion, bacterial disease response, self-incompatibility, and stomatal resistance. It is linked to membrane fission, protein secretion, MAPK cascade signaling, regulation of meristem and floral meristem development, cytokinesis, and biofilm formation. The encoded protein localizes to the plasma membrane, endosome, and extracellular space. Studies of related LRR-extensin-like regulators in other species connect the family to fruit shape.
