HD1 — Sorghum bicolor

Summary

SbHD1 (SORBI_3003G200400) on sorghum chromosome 3 encodes a protein with histone deacetylase activity, NAD-independent, and belongs to the His_deacetylse domain family. It is also annotated with histone demethylase, methyltransferase, transcription regulator, transcription corepressor, histone deacetylase binding, histone binding, AT binding, deacetylase activity, calcium-dependent protein serine/threonine kinase activity, structural constituent of chromatin, and transcriptional co-regulator activities. In sorghum, SbHD1 is associated with abiotic stress tolerance, melatonin metabolism, negative regulation of seed maturation, fruit abscission, regulation of multicellular organismal development, negative regulation of floral organ abscission, galacturonan metabolism, regulation of seed maturation, cellular response to external biotic stimulus, zygote asymmetric cytokinesis in embryo sac, proximodistal axis specification, response to diterpene, response to actidione, response to silver ion, regulation of cellular response to basic pH, regulation of embryonic development, hypermethylation of CpG island, upregulation of unidimensional cell growth, and downregulation of short-day photoperiodism, flowering. It localises to HDAC, PRC2 and Cul4-RING E3 ubiquitin ligase complexes, condensed chromosomes, the nucleolus, chloroplast envelope and plastid. The gene is linked to traits including floral organ length, fruit ripening, leaf elongation, branch angle, plant size
