HD1 — Zea mays

Summary

ZM00001EB084120 (HD1, ZmHD1) on maize chromosome 2 encodes a histone deacetylase with NAD-independent activity, also annotated for histone deacetylase binding, histone demethylase activity, transcription corepressor activity, and structural chromatin constituent roles. It is associated with regulation of stress response, protein acetylation, oxidative demethylation, alpha-tubulin acetylation, and negative regulation of seed maturation. The gene is linked to traits including tassel branch number, leaf elongation rate, branch angle, plant female sterility, fruit ripening, total soluble sugar content, brassinosteroid content, gibberellin biosynthesis, vegetative to reproductive phase transition, and responses to drought, salinity, and biotic stress. It localizes to the HDAC complex, PRC2 complex, condensed chromosome, nucleolus, and chloroplast envelope. Related genes in other species link the family to flower development, shoot development, abscisic acid response, and systemic acquired resistance.
