Project description:

Quantitative analysis of the cellular growth dynamics during lateral plant growth
Radial growth of plant shoots and roots is based on the activity of a group of stem cells, the cambium, and essential for generating large plant bodies. Thereby, it substantially contributes to the dominance of seed plants in terrestrial ecosystems, to wood formation and thus to carbon immobilization. In addition, the process represents a striking example for a constant remodelling of adult body structures and for stem cell regulation. Thus, lateral growth provides excellent opportunities for addressing the fundamental question of how cellular properties are integrated and adapted during the growth of adult organisms. Depending on the interest of the student, we offer the opportunity to investigate cell fate regulation in the context of cambium activity with a molecular, biochemical, evolutionary or computational angle.

Methods that will be used:
Computational Modelling
Confocal microscopy
Cooperation partners:
Jan Lohmann (Heidelberg University), Karin Schumacher (Heidelberg University)
Personal qualifications:
The ideal candidate should be willing to learn and establish novel technologies and be interested in quantitative aspects of developmental processes and in evolution. A background in molecular biology, imaging, image analysis or computational modelling would be desirable. He/she should also be able to work independently as well as in a team, be well organised and prepared to work in an international environment. Good interpersonal communication skills are essential.
