GRF1 — Oryza sativa Indica Group

Summary

BGIOSGA035433 (OiGRF1) on chromosome 11 of Indica rice encodes a growth-regulating factor (GRF) protein containing QLQ and WRC domains, with transcription coactivator activity, DNA-binding transcription factor activity, and ATP and protein binding. It localises to the nucleus and is associated with gibberellin and auxin responses, cell division, leaf and lamina joint development, tiller number, plant architecture, chilling stress tolerance, spikelet development, and yield. The gene is also linked to seed development, leaf morphogenesis, root meristem growth, leaf senescence, salt response, and nematode response. Additional associations include water use efficiency, anthocyanin content, oxidative stress response, and traits such as seed weight, leaf morphology, floral organ development, and seedling growth.
