Laboratory of Phylogeny and Molecular Genetics
(resp. Dr M. Perret)

The aim of the laboratory is to explore the evolution of biodiversity based on the analysis of molecular data. Research activities are carried out at two different levels: one is interspecific using phylogenetic approaches and the other is intraspecific using the tools of population genetics and phylogeography.

By providing new insights into the evolutionary history of plants and fungi, our results contribute to improve their classification and to better understand the origin of their outstanding diversity.

Principal techniques used in the laboratory

The laboratory has the capacity to receive 6-8 people fulltime. The laboratory is fully equipped with an automatic sequencer (GenomeLab GeXP™ Genetic Analysis System), which is also able to analyze DNA fragments (microsatellites, AFLP, SNP) and several PCR machines, including a real-time PCR instrument (Corbett RotorGene).

Research projects at the CJB conducted in the laboratory

Academic and Professional training

The laboratory hosts students from the University of Geneva, within the framework of Doctoral and Masters thesis (option “Biodiversity and Systematics” and “Molecular Plant Science”).

The laboratory also welcome visiting students from other Swiss and foreign academic institutions (doc and posdoc) and trains laboratory technicians in biology (CFC) linked with the AGEMEL.
