NUT — Nicotiana attenuata

Summary

A4A49_38143 (NUT) in coyote tobacco (Nicotiana attenuata) encodes a polygalacturonase-inhibiting protein (PGIP) with leucine-rich repeat domains and multiple molecular functions including peptide hormone binding, receptor serine/threonine kinase activity, calmodulin binding, and ubiquitin ligase binding. The gene is associated with response to nutrient levels, cellular response to salicylate, autophagy, lignin anabolism, specification of floral organ number, stomatal complex morphogenesis, and lateral root development. It localizes to the apoplast, plant-type cell wall, plasmodesma, membrane, and nucleus. Associations with self-incompatibility, brassinosteroid sensitivity, disease resistance, immune signaling, abscisic acid signaling, mannitol stress tolerance, and shade avoidance have been noted. Studies of related genes in other species link the family to pathogen resistance, bacterial disease response, stomatal resistance, and days to flowering trait.
