HD1 — Brachypodium distachyon

Summary

BdHD1 (BRADI_5G09190V3) on Brachypodium distachyon chromosome 5 encodes a protein with a His_deacetylse domain and is annotated with histone deacetylase activity, NAD-independent, as well as histone demethylase activity, transcription corepressor activity, and calcium-dependent protein serine/threonine kinase activity. The gene is associated with regulation of seed maturation, melatonin metabolism, fruit abscission, and responses to biotic stimuli and diterpenes. It is linked to traits including floral organ length, fruit ripening and quality, leaf elongation rate, branch angle, plant size, lignin biosynthesis, and vegetative-to-reproductive phase transition. Phenotypic associations include drought and salinity tolerance, abiotic and biotic stress responses, abscisic acid and jasmonic acid signaling, reproductive development, spikelet development, and cell division. Studies of related genes in other species connect the family to salt tolerance, brassinosteroid signaling, root and shoot development, flowering time, and grain yield traits.
