HD1 — Oryza sativa Indica Group

Summary

BGIOSGA037146 (HD1, also known as OiBBX30) on chromosome 12 of Indica rice encodes a B-box zinc finger protein with DNA binding transcription factor activity, localising to the nucleus. This gene is associated with the regulation of photoperiodism and flowering, including upregulation of short-day flowering and downregulation of long-day flowering, as well as photomorphogenesis, cell differentiation, and DNA-dependent transcription. It has been connected to several agronomically important traits, including days to heading, panicle number, spikelet fertility, grain number, grain weight, grain yield per plant, plant height, anthesis time, cold tolerance, and amino acid and protein content.
