GW8 — Oryza sativa Indica Group
Summary
BGIOSGA029051 (GW8, also known as SPL18, SPL13A, or SPL13B) on chromosome 8 of Indica rice encodes a protein with an SBP domain that binds DNA and zinc, localizes to the nucleus, and is associated with regulating transcription. This gene is associated with grain number, weight, width, and size, as well as spikelet dimensions, grain thickness, length, shape, and yield. It is linked to cell proliferation, tiller number, panicle and spikelet development, anther development, the vegetative-to-reproductive phase transition, and response to fungi. Additional associations include stigma exsertion, leaf morphology, adventitious root development, somatic embryogenesis, and root apical meristem phase transition. Studies of related SBP-domain proteins in other species link the family to traits such as inflorescence branching, seed size, plant height, heading time, and stress tolerance.
