Arbeitsgruppe (AG) Schnittger is a cell cycle research group based at the Max Planck Institute for Breeding Research in Cologne, Germany. Founded as a collaborative effort with the University of Cologne's Department of Botany, the group was first established in 2002 and has been led since that time by well-regarded science researcher Dr. Arp Schnittger. The group is normally comprised of doctoral candidates, post-doctoral researchers, diplom student researchers from the local university, and various transient members.

[edit] Research

The group utilizes Arabidopsis thaliana as a model organism to investigate cell cycle control. According to their website[1], this exploration takes place at different levels and makes use of new advances in many methods and techniques. On the molecular level, they are interested in the plant specific regulators of cell cycle control, such as large cyclin families with still unknown functions. On a cellular level, they explore the connection between cell cycle control and differentiation; in specific, they make use of well-described model cells, such as trichomes, stomata and root hairs. Finally, on an organ and organism level they study the integration of cell cycle regulation in organ growth and function
