Molecular Phytopathology Department

The Myc-Lab

Welcome to the Molecular Phytopathology Department!

Our group belongs to the Botanical Institute, and we recently moved to the South Campus of the Karlsruhe Institute of Technology in the Building 30.43, 2nd. Floor. We share the infrastructure with two Departments (Microbiology and  Genetics) from the Institute for Applied Biosciences. The research focus of our group is the molecular understanding of the interaction between microorganisms, particularly fungi, and plants.

Our latest paper in Current Biology:

Arbuscular mycorrhiza symbiosis induces a major transcriptional reprogramming of the potato SWEET sugar transporter family

by Manck-Götzenberger J and Requena N (2016)

Frontiers in Plant Science (doi:  10.3389/fpls.2016.00487)

Significance

Biotrophic microbes feeding on plants must obtain carbon from their hosts without killing the cells. The symbiotic arbuscular mycorrhizal (AM) fungi colonizing plant roots do so by inducing major transcriptional changes in the host that ultimately also reprogram the whole carbon partitioning of the plant. Recently a novel type of plant sugar transporter, the SWEET, able to perform not only uptake but also efflux from cells was identified. Plant SWEETs have been shown to be involved in the feeding of pathogenic microbes and are, therefore, good candidates to play a similar role in symbiotic associations. Here we have carried out the first phylogenetic and expression analyses of the potato SWEET family and investigated its role during mycorrhiza symbiosis.
