FLS2 — Oryza sativa Indica Group

Summary

BGIOSGA023157 (symbol FLS2, preferred name OiFON1) on Indica rice chromosome 6 encodes a non-specific serine/threonine protein kinase with transmembrane receptor protein kinase activity, belonging to the plant LRR-RLK family. The gene is associated with stem cell proliferation, floral organ development, specification of floral organ number, regulation of meristem organisation and size, anther wall tapetum development, microsporogenesis, megasporogenesis, and gametophyte development. It is linked to the TCA cycle, phenylpropanoid anabolism, regulation of stomatal complex development, and activation of defence response to bacteria. Associations with agronomic traits include grain number, grain weight, grain yield, panicle number, tiller number, and floral organ number. The product localises to the plasma membrane, ER membrane, perinuclear ER, cortical ER, nucleus, and extracellular space.
