PAT — Nicotiana attenuata

Summary

A4A49_63215 (PAT, UBI3) on chromosome 1 of coyote tobacco encodes a protein with ubiquitin and ribosomal eS31 domains, possessing structural constituent of ribosome, ubiquitin-protein transferase, histone acetyltransferase, and double-stranded methylated DNA binding activities. It 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. The gene is linked to traits including photosynthetic rate, respiration rate, chloroplast development, and high and low temperature stress responses, as well as phenotypes such as increased salt stress response, decreased oxidative stress response, abscisic acid sensitivity, chloroplast function and development, protein degradation, DNA methylation, and gene silencing. Related genes in other species are linked to heat and temperature stress tolerance and wound response.
