NUT — Nicotiana attenuata

Summary

A4A49_36281, designated NUT in coyote tobacco (Nicotiana attenuata) on chromosome scaffold01752, encodes a non-specific serine/threonine protein kinase with transmembrane receptor protein kinase activity and receptor serine/threonine kinase binding. The product belongs to the plant receptor-like S/T kinase family and contains leucine-rich repeats. In this species, NUT is associated with autophagy, upregulation of defense response, lignin anabolism, activation of defence response to bacteria, stomatal complex morphogenesis, lateral root development, virus-induced PTGS, salinity response, heat acclimation, and plant ovule and embryo sac development. It localizes to the plasma membrane, ER membrane, perinuclear ER, cortical ER, extracellular region, and nucleus. NUT is also linked to self-incompatibility. Studies of related genes in other species connect the family to immune signaling and developmental regulation.
