SORBI_3010G176300 — Sorghum bicolor

Summary

SbHD1 (SORBI_3010G176300) on sorghum chromosome 10 encodes a protein with histone deacetylase activity, NAD-independent, and belongs to the His_deacetylse_1 domain family. The enzyme is associated with histone deacetylase binding, transcription regulator activity, and transcription corepressor activity, and is linked to the HDAC complex and PRC2 complex. In sorghum, SbHD1 is associated with abiotic stress tolerance. The gene has been connected to processes including melatonin metabolism, negative regulation of seed maturation, fruit abscission, and regulation of multicellular organismal development. Associations extend to traits such as floral organ length, fruit quality and ripening, plant female sterility, branch angle, leaf elongation rate, metabolite content, and responses to temperature stress, drought, and salinity. Studies of related genes in other species link the family to salt tolerance, brassinosteroid signaling, and grain yield traits.
