PAT — Beta vulgaris subsp. vulgaris

Summary

BvPAT (BVRB_7G159200) on sugar beet chromosome 7 encodes a protein with ubiquitin-like and ribosomal eL40 domains, annotated with structural constituent of ribosome, ubiquitin-protein transferase activity, thiol-dependent deubiquitinase, histone methylase activity, and core promoter sequence-specific DNA binding. The gene is associated with diverse biological processes including regulation of abscisic acid anabolism, cellular response to salicylate stimulus, upregulation of defense response to oomycetes, stomatal lineage progression, seed dormancy, endosperm development, and response to freezing. It is linked to traits such as leaf chlorophyll content, biomass yield, root mass density, plant height, flowering time, seed dormancy, pollen fertility, disease tolerance, and salt tolerance. Localization evidence connects the product to the cytosolic large ribosomal subunit, ribosome, early and late endosomes, ESCRT I complex, and chromosome. Studies of related genes in other species link the family to salt tolerance, drought tolerance, seed size, and cell proliferation.
