Abstract excerpt

Casparian strip (CS) seals the extracellular space between neighboring endodermal cells and helps plants maintain nutrient homeostasis. However, little is known about CS formation and function in rice. Here, we demonstrate that GAPLESS1/2/3, along with OsCASP1/2/3/5, redundantly regulate endodermal CS formation by forming an interdependent complex in rice. Triple knockout of GAPLESSs or quadruple knockout of...
