Staging of Emerged Lateral Roots in Arabidopsis thaliana

Abstract

The root system in plants plays a fundamental role in water and nutrient uptake. Lateral roots emerge from the primary root (PR) and its directional organ growth allows the plant to strategically explore the surrounding area. Compared to the main root, lateral roots initially display a distinct gravitropic set point angle, which is established shortly after emergence. Here, we describe a unifying protocol for the morphological description and classification of emerged, young lateral roots.
