HTD1 — Oryza sativa Japonica

Summary

OsHTD1 (HTD1, Os11g0134500) encodes a WD40 repeat-containing protein with histone-binding, transcription corepressor-binding, structural molecule activity, nucleic acid binding, and protein binding activities, and is associated with multiple chromatin-related complexes including the Cul4-RING E3 ubiquitin ligase complex and histone methyltransferase complex. The gene is linked to tillering capacity, grain size, seed shattering, plant height, flowering time, and chlorophyll content. It is associated with leaf senescence, chlorophyll breakdown, pollen development and maturation, downregulation of photomorphogenesis, and responses to arsenic, heat stress, UV light, and salt stress. OsHTD1 localises to the Golgi membrane, nucleolus, cytosol, and plant-type cell wall, and is associated with intra-Golgi transport, ER-to-Golgi transport, ribosome biogenesis, protein folding, and DNA replication and recombination.
