A receptor-like kinase mutant with absent endodermal diffusion barrier displays selective nutrient homeostasis defects

The endodermis represents the main barrier to extracellular diffusion in plant roots, and it is central to current models of plant nutrient uptake. Despite this, little is known about the genes setting up this endodermal barrier. In this study, we report the identification and characterization of a...
