FLS2 — Nicotiana attenuata

Summary

A4A49_32116 (FLS2) in coyote tobacco (Nicotiana attenuata) on chromosome scaffold02477 encodes a transmembrane receptor serine/threonine kinase with steroid and SNARE binding activities, classified as EC 2.7.11.1. The gene is associated with detection of brassinosteroid stimulus, hormone-mediated signaling, and activation of defense responses to bacteria, as well as upregulation of defense and salinity responses. It is also associated with viral translation, endocytosis, membrane fission, microtubule bundling, stomatal complex morphogenesis, anther wall tapetum development, megasporogenesis, microsporogenesis, plant ovule development, and skotomorphogenesis. The encoded protein localizes to the plasma membrane, ER membrane, endosome, nucleus, and extracellular region. Studies of related genes in other species connect the FLS2 family to bacterial disease response, self-incompatibility, and stomatal resistance.
