GHD7 — Oryza sativa Indica Group

Summary

BGIOSGA024502 (Ghd7) on chromosome 7 of indica rice encodes a CONSTANS-like, CCT-domain-containing transcription factor with DNA-binding and zinc-binding activity, localised to the nucleus. It is associated with the regulation of photoperiodism, flowering, and vernalization response, and has been connected to downregulation of flowering under both short and long days. Ghd7 is linked to numerous agronomic traits, including flowering time, heading date, plant height, grain yield, grain number, grain size and weight, panicle number and size, spikelet fertility, amylose and protein content, chlorophyll content, photosynthetic rate, leaf size, stay-green trait, heterosis, and stress responses encompassing both abiotic and biotic stress, as well as domestication and adaptability.
