Pecinka lab

Research

The goal of Pecinka lab is to understand molecular basis of mechanisms shaping plant genomes. We focus in particular on DNA repair and inactivation of repetitive DNA that both have potential to cause large genomic chages. To this end we use model species Arabidopsis thaliana and several other Brassicaceae and analyze them using forward and reverse genetics, molecular, biochemical, cytogenetic and bioinformatic methods.

Pecinka lab is hosted by the Department of Plant Breeding and Genetics at the Max Planck Institute for Plant Breeding Research in Cologne, Germany.

Our wiki site is developed under Openwetware, an open access effort to promote the sharing of information among researchers working in biology.
