FLS2 — Solanum lycopersicum

Summary

SOLYC03G083510.4, designated SlNIK2 and also known as FLS2, encodes a transmembrane receptor serine/threonine kinase with leucine-rich repeat domains, possessing protein kinase, signaling receptor, and steroid- and SNARE-binding activities. In tomato, this gene is associated with bacterial disease response, self-incompatibility, and stomatal resistance. It is associated with immune evasion, the MAPK cascade, membrane fission, cytokinesis, post-embryonic plant organ development, regulation of floral meristem size, and biofilm formation. The encoded protein localizes to the plasma membrane, endosome, ER membrane, nucleus, and extracellular region. Studies of related genes in other species connect the family to non-specific serine/threonine protein kinase activity (EC 2.7.11.1) and to traits including stem elongation and plant height.
