HD1 — Brachypodium distachyon

Summary

BdHD1 (BRADI_3G44780V3) encodes a protein with a His_deacetylse domain and is associated with histone deacetylase activity, NAD-independent, as well as histone demethylase activity, transcription corepressor activity, and calcium-dependent protein serine/threonine kinase activity. In Brachypodium distachyon, this gene is linked to regulation of seed maturation, floral organ abscission, fruit ripening, and melatonin metabolism. It is associated with traits including drought and salinity tolerance, abiotic and biotic stress responses, gibberellin and brassinosteroid content, lignin biosynthesis, leaf elongation rate, branch angle, and total soluble sugar content. The encoded protein localizes to the HDAC complex, PRC2 complex, nucleolus, and chloroplast envelope. Studies of related genes in other species associate the family with salt tolerance, root development, flowering time, and grain yield.
