HD1 — Brachypodium distachyon

Summary

BdHD1 (BRADI_3G08060V3) on Brachypodium distachyon chromosome 3 encodes a protein with histone deacetylase activity, NAD-independent, and belongs to the His_deacetylse domain family. The gene product is associated with histone deacetylase binding, transcription corepressor activity, and structural constituent of chromatin. BdHD1 is linked to melatonin metabolism, negative regulation of seed maturation, fruit abscission, and regulation of multicellular organismal development. It is associated with traits including floral organ length, fruit ripening, leaf elongation rate, branch angle, plant female sterility, and responses to temperature stress, drought, and salinity. The protein localizes to HDAC and PRC2 complexes, the nucleolus, and chloroplast envelope. Studies of related genes in other species link the family to salt tolerance, brassinosteroid signaling, and grain yield, while related genes in other species are connected to flower development and systemic acquired resistance.
