PAT — Beta vulgaris subsp. vulgaris

Summary

BvPAT (BVRB_000420) on sugar beet chromosome 0010.scaffold00043 encodes a protein with ubiquitin and ribosomal eL40 domains, annotated with structural constituent of ribosome, ubiquitin-protein transferase, thiol-dependent deubiquitinase, histone methylase, and DNA-binding activities. The gene is associated with 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 oomycete and bacterial defense. It is linked to traits including leaf chlorophyll content, biomass yield, plant height, root mass density, seed dormancy, flowering time, pollen fertility, leaf necrosis, temperature stress response, disease tolerance, and salt tolerance. Localization evidence connects the product to ribosomes, endosomes, the ESCRT I complex, and chromosomes. Studies of related genes in other species link the family to cold and heat stress tolerance, immunity, leaf senescence, and fruit development.
