OsKAT1 is a short Shaker potassium channel involved in root-to-shoot potassium translocation and contributes to rice grain yield

Proceedings of the National Academy of Sciences, Volume 123, Issue 5, February 2026. <br/>SignificanceK+transport from root to shoot is a critical process for sustaining physiological functions in aerial organs. We report here a short inward channel OsKAT1, localized in the root stele of rice, which contributes to root–shoot K+translocation. …
