Ghd7‑triggered transcriptional regulation for synergistically improving rice eating quality and yield.

Ghd7-triggered transcriptional regulation, combined with PCF3‑T, enhances both rice yield and eating quality by balancing starch and protein content.

• Why it matters: Balancing rice yield and eating quality is a longstanding challenge in breeding, with most efforts improving one trait often compromising the other. Addressing this gap could lead to more nutritious and productive rice varieties.
• What they did: Researchers identified Ghd7 as the key gene influencing grain amylose content and used haplotype and evolutionary analyses to explore the effects of PCF3 variants, focusing on their roles in transcriptional regulation.
• The result: The combination of Ghd7‑1/4 alleles with the PCF3‑T variant significantly boosts both yield and eating quality, providing promising genetic targets for simultaneous improvement in rice breeding programs.
