HD1 — Brachypodium distachyon

Summary

BdHD1 (BRADI_2G42075V3) on chromosome 2 of Brachypodium distachyon encodes a protein with a His_deacetylse domain family. The protein also exhibits histone deacetylase activity, NAD-independent, histone demethylase activity, transcription regulator activity, transcription corepressor activity, calcium-dependent protein serine/threonine kinase activity, histone binding, and AT binding. BdHD1 is associated with the regulation of seed maturation, floral organ abscission, fruit ripening, and melatonin metabolism. It has been linked to traits including drought and salinity tolerance, abiotic and biotic stress responses, gibberellin and brassinosteroid content, lignin biosynthesis, leaf elongation rate, branch angle, whole plant size, and reproductive development. The protein localizes to the HDAC complex, PRC2 complex, nucleolus, and chloroplast envelope. Studies of related genes in other species connect the family to salt tolerance, flower development, and systemic acquired resistance.
