PAT — Beta vulgaris subsp. vulgaris

Summary

BvPAT (BVRB_7G159160) on sugar beet chromosome 7 encodes a protein with ubiquitin and ribosomal eL40 domains, and is annotated with structural constituent of ribosome, ubiquitin-protein transferase, thiol-dependent deubiquitinase, histone methylase, and DNA-binding activities. The gene is associated with diverse biological processes including modification-dependent proteolysis, deubiquitination, regulation of abscisic acid and salicylic acid signaling, stomatal lineage progression, seed dormancy, endosperm development, and responses to freezing, thermal stimulus, salinity, and oomycetes. It is linked to traits such as biomass yield, plant height, root mass density, leaf chlorophyll content, seed dormancy, flowering time, pollen fertility, disease tolerance, and temperature stress responses. Localization evidence connects the product to ribosomes, endosomes, and the ESCRT I complex. Studies of related genes in other species link the family to salt and drought tolerance, cell proliferation, and seed size.
