PAT — Nicotiana attenuata

Summary

A4A49_39502 (PAT, also known as UBQ10) on coyote tobacco chromosome 1 encodes a protein with ubiquitin domains and is annotated with diverse molecular functions including histone methylase activity, thiol-dependent deubiquitinase activity, ubiquitin-protein transferase activity, and structural constituent of ribosome. The gene is associated with modification-dependent proteolysis, deubiquitination, regulation of abscisic acid anabolism, cellular response to salicylate stimulus, upregulation of defense response to oomycetes, stomatal lineage progression, seed dormancy, endosperm development, and trichome branching. It localizes to the ESCRT I complex, endosomes, chromosome, cytosolic ribosome, and ER membrane. Associations include leaf necrosis, chlorophyll content, biomass yield, plant height, flowering time, seed dormancy, disease tolerance, and responses to temperature stress. Studies of related genes in other species link the family to salt and drought tolerance, cell proliferation, and seed size.
