Abstract excerpt

Lodging decreases crop yields, but a strong stem improves lodging resistance in grains such as rice (Oryza sativa). In this study, we determined that the R2R3-type MYB transcription factor Robust Root System 1 (RRS1) negatively regulates culm mechanical strength in rice by affecting culm diameter and culm wall thickness. Specifically, RRS1 reduces culm diameter by directly activating STRONG1 expression, which in...
