What will be your task?
You will be building and analyzing dynamical models of lateral root initiation, in close collaboration with molecular biologists in the research group Root Development headed by Dr. Tom Beeckman.
Lateral roots originate from cells in the root basal meristem, a proliferating tissue region just above the root tip, forming a regular branching pattern with evenly spaced lateral roots. The crucial signal for initiating the lateral root is most likely the phytohormone auxin. Auxin levels oscillate at a period of around 15 hours, precisely coinciding with the rhythm by which new lateral roots appear. Our modeling project aims at unraveling the mechanisms behind these oscillating auxin flows, which may be driven by a dynamics interaction between auxin and the production and cellular localization of its transporter proteins, including PIN, AUX and LAX. In the second part of your project you will also include root growth and the tightly orchestrated cell divisions following lateral root initiation.
