PAT — Nicotiana attenuata

Summary

A4A49_32310 (PAT, UBI3) on chromosome 2 of coyote tobacco encodes a protein with ubiquitin and ribosomal eS31 zinc-binding domains, and is annotated with structural constituent of ribosome, ubiquitin-protein transferase, histone acetyltransferase, and double-stranded methylated DNA binding activities. The gene is associated with translation, protein ubiquitination, modification-dependent proteolysis, fermentation, RNA-directed DNA methylation, cell death, and responses to abscisic acid, salinity, and thermal stimuli. It is linked to traits including photosynthetic rate, respiration rate, chloroplast development, and stress responses to high and low temperatures. Phenotype associations include increased salt stress response, decreased oxidative stress response, abscisic acid sensitivity, cold tolerance, chloroplast function and development, protein degradation, and DNA methylation/silencing. Studies of related genes in other species link the family to heat and temperature stress tolerance and wound response.
