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

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

• Why it matters: Improving rice yield and eating quality simultaneously remains a key challenge in breeding, with limited understanding of the underlying genetic mechanisms.
• What they did: Researchers identified Ghd7 as the causal gene for grain amylose content and examined its regulation of PCF3, analyzing natural variants and their effects on starch and protein levels in rice grains.
• The result: Combining Ghd7‑1/4 alleles with the PCF3‑T variant further improves both yield and eating quality, suggesting these genes as promising targets for rice breeding programs.
