GHD7 — Brachypodium distachyon

Summary

BRADI_3G10010V3 (GHD7, VRN2) in Brachypodium distachyon encodes a CONSTANS-like, CCT domain-containing protein with DNA binding transcription factor activity. This gene is associated with the regulation of photoperiodism, flowering, and vernalization response, including both upregulation and downregulation of short-day and long-day flowering pathways. It is linked to anthesis time, heading date, floral development, and yield-related traits such as grain number, panicle size, and photosynthetic rate. Additional associations include grain cadmium concentration, temperature response, and domestication. The protein localizes to the nucleus and is connected to cell differentiation and DNA-dependent transcription. Studies of related genes in other species link the family to flowering time, grain traits, panicle architecture, stress responses, and developmental processes.
