PAT — Nicotiana attenuata

Summary

NaPAT (A4A49_62968) on chromosome 1 of coyote tobacco encodes a ubiquitin-60S ribosomal protein L40, a fusion protein that combines a ubiquitin domain with a ribosomal eL40 domain. The product is annotated with histone methylase activity, core promoter and cis-regulatory sequence-specific DNA binding, thiol-dependent deubiquitinase activity, and structural ribosome constituent function. It is associated with modification-dependent proteolysis, deubiquitination, regulation of abscisic acid and salicylic acid signaling, stomatal lineage progression, seed dormancy, endosperm development, trichome branching, and responses to freezing, salinity, bacteria, and oomycetes. Traits linked to this gene include leaf chlorophyll content, biomass yield, plant height, flowering time, seed dormancy, root mass density, pollen fertility, shoot branching, leaf necrosis, and temperature stress responses. Studies of related genes in other species connect the family to salt and drought tolerance, cell proliferation, and seed size.
