H4 — Zea mays

Summary

ZmH4 (ZM00001EB313730) on maize chromosome 7 encodes a core histone H4 protein, a structural constituent of chromatin with histone-fold and CENP-T/H4_C domains. The gene product is associated with histone acetylase, deacetylase, methylase, and DNA-binding activities, and is linked to chromatin decompaction, DNA replication licensing, telomeric silencing, mitosis, and sucrose breakdown. ZmH4 is associated with grain yield, plant height, flowering time, anthesis time, seed maturation and development, heterosis, bacterial blight disease resistance, heat and salinity tolerance, leaf and root morphology, shoot branching, chloroplast development, and jasmonic acid content. It localizes to multiple cellular compartments including the nucleolus, thylakoid, chloroplast envelope, and plasmodesmata, and is a component of TIP60, Sin3-type, and SWR-C complexes.
