The exodermis is a physiological barrier that has a role in root function and protection.[1] The exodermis is a membrane of variable permeability responsible for the radial flow of water, ions, and nutrients.[2][3] It is the outer layer of a plant's cortex.[1][4] The exodermis serves a double function as it can protect the root from invasion by foreign pathogens and ensures that the plant does not lose too much water through diffusion through the root system and can properly replenish its stores at an appropriate rate.[5]
