PAT — Nicotiana attenuata

Summary

A4A49_31741 (PAT, UBQ10) in coyote tobacco (Nicotiana attenuata) encodes a ubiquitin-domain protein with histone methylase, deubiquitinase, and ubiquitin-protein transferase activities, and also functions as a structural constituent of the ribosome. It is associated with diverse biological processes including modification-dependent proteolysis, deubiquitination, regulation of abscisic acid and salicylic acid signaling, seed dormancy, endosperm development, trichome branching, and responses to freezing, salinity, and oomycetes. The gene is linked to numerous agronomic traits such as biomass yield, plant height, leaf chlorophyll content, flowering time, seed dormancy, root mass density, pollen fertility, disease tolerance, and temperature stress responses. It localizes to the ER membrane, endosomes, chromosomes, and cytosolic ribosomes. Studies of related genes in other species connect the family to fruit development, leaf senescence, immunity, and cold and heat stress tolerance.
