FLS2 — Nicotiana attenuata

Summary

A4A49_59506, the FLS2 gene on coyote tobacco (Nicotiana attenuata) scaffold01371, encodes a leucine-rich repeat receptor-like kinase (LRR-RLK) with transmembrane receptor serine/threonine kinase activity, protein serine kinase activity, and steroid, SNARE, and signaling receptor binding functions. The gene is associated with activation of defence response to bacteria, upregulation of defense response, endocytosis, membrane fission, viral translation, and regulation of cell growth. It is linked to floral organ development, specification of floral organ number, regulation of floral meristem size, anther wall tapetum development, microsporogenesis, megasporogenesis, gametophyte development, stomatal complex morphogenesis, regulation of stomatal complex development, skotomorphogenesis, and microtubule bundling. The product localizes to the plasmalemma, ER membrane, perinuclear ER, cortical ER, endosome, and nucleus. Related genes in other species link the family to flagellin perception and defence signalling.
