PAT — Nicotiana attenuata

Summary

A4A49_29449 (PAT, also known as UBQ4) in coyote tobacco (Nicotiana attenuata) encodes a protein with ubiquitin domains and is annotated with diverse molecular functions including histone methylase activity, thiol-dependent deubiquitinase activity, and structural constituent of the ribosome. The gene is associated with modification-dependent proteolysis, deubiquitination, and regulation of abscisic acid anabolism. It has been linked to cellular responses to salicylate stimulus, activation of defence against bacteria and oomycetes, and stomatal lineage progression. Associations with agronomic traits include leaf chlorophyll content, biomass yield, plant height, seed dormancy, flowering time, root mass density, and responses to temperature stress, salinity, and freezing. The gene is also linked to petal size, stamen morphology, pollen fertility, and shoot axis branching. Related genes in other species are associated with seed size, salt and drought tolerance, and cell proliferation.
