GHD7 — Oryza sativa Indica Group

Summary

BGIOSGA031408 (GHD7, OiCCT35) on chromosome 10 of Indica rice encodes a CCT domain-containing protein belonging to the CONSTANS-like family and acts as a DNA-binding transcription factor with zinc-binding activity, localised to the nucleus. The gene is associated with the regulation of photoperiodism and flowering, including upregulation and downregulation of short-day and long-day photoperiodism, vernalization response, flower development, sumoylation, and cell differentiation. It is also associated with numerous agronomically important traits, such as days to heading, grain yield, grain weight, grain number, grain size and shape, spikelet number and fertility, panicle number, plant height, leaf size and width, chlorophyll content, stay green trait, amylose and protein content, amino acid content, heterosis, and anthesis time.
