PI21 — Oryza sativa Japonica

Summary

OS11G0629100, designated PI21 in rice (Oryza sativa Japonica) on chromosome 11, encodes a protein containing a heavy metal-associated domain superfamily (HMA_dom_sf) and is annotated with metal-binding molecular function. The gene is associated with regulation of defence response to fungi and defence response to fungi. Additionally, PI21 is linked to panicle number, tiller number, grain number, grain weight, and plant height. Related genes in other species encode HMA domain-containing proteins, but this is not established for PI21 itself.
