Quantitative analysis of the suberisation wavefront in the Arabidopsis thaliana root

Abstract

Suberin is a hydrophobic biopolymer found in the endodermis of plants, which provides protection against various biotic and abiotic stresses and regulates the nutrient and water uptake in the plants. Despite having a major role in the functioning of plants, there is less knowledge about the developmental patterning of the suberin. Understanding suberin development in plants is important for generating stress-resilient plants. This work proposes a live-imaging and quantitative framework to study and analyse the progression of the suberin front. This study confirms that suberin progression in the root of A. thaliana serves as a model for investigating traveling wavefronts in plants.
