HB-3 — Oryza sativa Japonica

Summary

Rice gene OS03G0325600, also known as HB-3, WOX6, WOX11, and STIP, encodes a homeodomain-containing transcription factor of the WOX11-like family. The product possesses DNA binding, transcription factor, transcription coactivator, and protein binding activities. In rice, this gene is associated with crown root development, initiation, emergence, and elongation, as well as root architecture, root initiation, and adventitious root. It is linked to auxin and cytokinin, drought resistance, tiller, biomass, and potassium. The gene is also associated with transdifferentiation, regeneration, meristem development, organogenesis, gibberellic acid homeostasis, and regulation of seed dormancy. Associations extend to grain yield, plant height, tiller number, flowering time, seed set, male sterility, and leaf senescence. The protein localizes to both the nucleus and cytoplasm.
