Dirk Redecker

Work Address:

Before joining the Bruns lab, Dirk was a PhD student and postdoc in Dr. Dietrich Werner's lab at Philipps-Universität in Marburg, Germany.

While in the Bruns lab from May 1997 through July 2000, he worked on the molecular phylogeny and identification of Arbuscular Mycorrhizal (AM) Fungi. Using 18S rDNA and ITS sequences, he characterized a group of AM fungi that are only distantly related to the previously analyzed families and constitute deeply divergent lineages of the AM fungi. These fungi are difficult to detect both with conventional staining methods and previously designed molecular tools. Therefore specific PCR primers were designed for these lineages and other subgroups of the AM fungi to facilitate detection of symbionts within roots. Morphological descriptions of some of the ancestral lineages that have been analyzed can be found on the INVAM website. Two new genera, Archaeospora and Paraglomus, were established for them, each in a new family.

Dirk also studied the phylogeny of "Sclerocystis" species. As a consequence of the results, the last species of Sclerocystis was placed in Glomus. A 5.8S dataset he compiled allows one to check ITS sequences for the organism they originate from.

Dirk was also working on a project about genet sizes of ectomycorrhizal fungi, characterizing populations of Russula, Lactarius and Suillus in field sites in Northern California.

In addition, he was involved in a project studying the oldest known fungal fossils from the Ordovician (460 million years ago).

From August to October 2000, he conducted experiments in Dave Rizzo's lab at the University of California at Davis.

In January 2001, Dirk started a job at the University of Basel (Switzerland), where he studies the ecology of AM fungi.

In September 2009, Dirk will joined the faculty at the University of Burgundy in Dijon, France.
