NUT — Nicotiana attenuata

Summary

A4A49_01213 (NUT, also known as PGIP2) in coyote tobacco (Nicotiana attenuata) on chromosome 10 encodes a protein with PGIP and leucine-rich repeat domains, exhibiting multiple molecular functions including peptide hormone binding, signaling receptor activity, calmodulin binding, transmembrane receptor serine/threonine kinase activity, and protein kinase activity. The gene is associated with response to nutrient levels, cellular response to salicylate stimulus, autophagy, lignin anabolism, stomatal complex morphogenesis, lateral root development, and hormone-mediated signaling. It localizes to the apoplast, plant-type cell wall, plasmodesma, membrane, and nucleus. Associations include self-incompatibility, brassinosteroid sensitivity, disease resistance, immune response, mannitol stress tolerance, abscisic acid signaling, and root elongation. Studies of related genes in other species link the family to pathogen resistance and traits including days to flowering, stomatal resistance, and abscisic acid sensitivity.
