NUT — Nicotiana attenuata

Summary

A4A49_00761 (NUT, also known as RLK5) in coyote tobacco (Nicotiana attenuata) on chromosome 6 encodes a transmembrane receptor serine/threonine kinase with leucine-rich repeat domains, exhibiting peptide hormone binding, calmodulin binding, and ubiquitin ligase binding activities. This gene is associated with responses to nutrient levels, cellular response to salicylate stimulus, autophagy, floral organ development and specification of floral organ number, regulation of meristem organisation, lignin anabolism, stomatal complex morphogenesis, lateral root development, and virus-induced PTGS. It has been connected to self-incompatibility, brassinosteroid sensitivity, disease resistance, immune response, mannitol stress tolerance, calcium signaling, abscisic acid signaling, shade avoidance, and root elongation. The protein localises to the plasma membrane, plant-type cell wall, plasmodesma, extracellular region, cytosol, and nucleus. Studies of related genes in other species link the family to pathogen resistance.
