PAT — Beta vulgaris subsp. vulgaris

Summary

BvPAT (BVRB_2G046140) on sugar beet chromosome Bvchr2_un.sca006 encodes a protein with ubiquitin domains and is annotated with diverse molecular functions including histone methylase activity, ubiquitin-protein transferase activity, DNA binding, and structural constituent of ribosome. The gene is associated with numerous biological processes such as modification-dependent proteolysis, deubiquitination, regulation of abscisic acid anabolism, response to freezing, thermal stimulus, and defense responses to bacteria and oomycetes. It has been linked to traits including leaf necrosis, chlorophyll content, biomass yield, plant height, root mass density, seed dormancy, flowering time, pollen fertility, disease tolerance, and salt tolerance. Localization evidence connects the product to ribosomes, endosomes, and the ESCRT I complex. Studies of related genes in other species link the family to cold and heat stress tolerance, immunity, leaf senescence, and stomatal formation.
