Regulation of lateral root development in Arabidopsis thaliana

Root system development provides an exemplary model for understanding how plants regulate organogenesis throughout their lifetimes, and how the process of post-embryonic organogenesis is coordinated with environmental cues. In this project we build on our previous work on the role of auxin transport and signal transduction in root development to obtain insights into the signaling networks and mechanisms that operate in lateral root formation and development.

Regulation der Arabidopsis thaliana Seitenwurzelentwicklung

Wurzeln stellen ein exzellentes System zum Studium postembryonaler Organentwicklung dar, da sie sich während des gesamten Lebenszyklus einer Pflanze in Abhängigkeit von Umwelteinflüssen neu entwickeln. Aufbauend auf unseren Arbeiten zur Rolle von Auxin in der Primärwurzelentwicklung planen wir die Untersuchung der molekularen Netzwerke, die die Entwicklung des Seitenwurzelprimordiums in die funktionsfähige Seitenwurzel steuern.
