HD1 — Sorghum bicolor

Summary

SORBI_3007G114000 (SbHD1) encodes a protein with histone deacetylase activity, NAD-independent, and is annotated with transcription corepressor activity and histone binding. In sorghum, SbHD1 is associated with abiotic stress tolerance and linked to melatonin metabolism, negative regulation of seed maturation, fruit abscission, and regulation of multicellular organismal development. The gene is associated with traits including floral organ length, fruit ripening, plant female sterility, branch angle, leaf elongation rate, metabolite content, and total soluble sugar content. It is also associated with drought, salinity, jasmonic acid, and abscisic acid, as well as reproductive development and spikelet development. Studies of related genes in other species link the family to salt tolerance, brassinosteroid signaling, root development, flower development, and abscisic acid response.
