Abstract excerpt

Casparian strip membrane domain proteins (CASPs) are required for Casparian strip (CS) formation. In rice, the loss of OsCASP1 leads to premature leaf senescence, increased salt sensitivity and ectopic suberin deposition. In order to elucidate the role of OsCASP1 in these biological pathways, the expression of related genes and the physiological phenotypes of the Oscasp1 mutant were analyzed. The present study...
