How plants create barrier in root tissue?
Plant roots are constantly challenged by the surrounding soil environment. To survive in such conditions, plant roots adapted to have apoplastic barriers in endodermis and exodermis cell layers. Although, Arabidopsis serves as a great model system to study many aspects of plant development, there are certain cell types, which is missing in Arabidopsis. Exodermis is one of those cell types.
Here is an example of exodermis formation over time. We tracked the wheat root from tip to the base. Each 20mm interval, we sectioned the root radially. As the movie progresses, you will see a progressive development of wheat exodermis barrier formation.

If we take a closer look in the following movie, you will see the exodermis barrier of wheat root in the 3D space.
In a similar way, we tracked maize root exodermis formation over time. Each 20mm interval, we sectioned the root radially. As the movie progresses, you will see a progressive development of maize exodermis barrier formation.
If we take a closer look in the following movie, you will see the exodermis barrier of maize root in the 3D space.
In this project, we explore how plants build these barriers in root using cellular, molecular, and genetic tools. Furthermore, we are interested to find out the function of exodermis barrier in challenging climate and during domestication.
