What are the function of cutin on the epidermis of the corn root?

Cutin is a waxy substance that forms a protective layer on the epidermis of corn roots, serving several key functions. It helps reduce water loss by creating a barrier against evaporation, thereby maintaining hydration in the root tissues. Additionally, cutin provides protection against pathogens and environmental stressors, contributing to the overall health and resilience of the plant. This layer also aids in regulating the uptake of water and nutrients from the soil.
