HD1 — Brachypodium distachyon

Summary

BdHD1 (BRADI_3G22370V3) on Brachypodium distachyon chromosome 3 encodes a histone deacetylase with NAD-independent activity, also annotated with histone demethylase, transcription regulator, and transcription corepressor activities, and belongs to the His_deacetylse domain family. The gene is associated with regulation of seed maturation, melatonin metabolism, fruit abscission, and responses to biotic stimuli and diterpenes. It has been linked to traits including floral organ length, fruit ripening and quality, branch angle, leaf elongation rate, total soluble sugar content, lignin biosynthesis, and vegetative-to-reproductive phase transition. Associations also include drought and salinity tolerance, abiotic and biotic stress responses, and reproductive development. Studies of related genes in other species connect the family to salt tolerance, grain yield, heading time, panicle number, and leaf angle.
