Ectomycorrhizal symbiosis and gene regulation
Pedunculate oak (Quercus robur L.) is a foundation forest tree species in the whole Northern hemisphere. Consecutively to forest degradation and after important storms, a reforestation research program was initiated in south of Germany in the 90s, with the goal to optimize the production of performing oak and beech saplings by replacing intensive fertilization in nurseries by inoculation with selected strains of symbiotic ectomycorrhizal fungi. In this frame Sylvie Herrmann started to work with the oak clone DF159 to get a continuous production of saplings by micropropagation in order to rationalize comparative performance tests of mycorrhizal fungal strains.

The preliminary established petri dish model system enabled us to investigate the interplays between mycorrhizal symbiosis and the expression of the endogenous rhythmic growth, a developmental trait characteristic of oak trees characterized by alternating shoot and root growth flushes. Based on the observation that inoculation of DF159 oak microcuttings with the ectomycorrhizal fungus (EMF) Piloderma croceum markedly triggers plant growth already before the onset of mycorrhiza formation, this dual model system was selected to study the regulation of photosynthesis and differential expression of plant genes at early stages of mycorrhizal symbiosis in the frame of the DFG Research Unit MolMyk (1084).
Impact of endogenous rhythmic growth (ERG) on multitrophic interactions under controlled conditions – development of an oak phytometer
In the frame of the DFG research consortium TrophinOak , we adapted the microcosm system with in vitro propagated plants of the oak clone DF159 to study the impact of endogenous rhythmic growth (ERG) on the interplay between plant development and above- or below-ground multitrophic interactions. Transcriptome analyses and pulse labelling with stable isotopes enabled us to compare the effects of beneficial and detrimental organisms interacting with the oaks at different phases of the ERG in mycorrhizal versus non-mycorrhizal plants. The results of such lab analyses constitute a baseline for a “PhytOakmeter” project, to monitor the behavior of clonal oaks after their field release in tree biodiversity experiments (MyDiv) or under various climatic and land use conditions in TERENO sites and across Europe.
Co-ordination of the TrophinOak/PhytOakmeter platform
These works done in particular in the frame of the DFG Research Unit MolMyk (1084) and the TrophinOak consortium led to the Oak Group that Sylvie Herrmann implemented at the UFZ in 2005 to develop the oak experimental platform
TrophinOak/PhytOakmeter
.
The group is responsible for the “Oak DF159 micropropagation unit” and delivers all clonal oak microcutting and saplings used for lab and field experimentations in the frame of the TrophinOak/PhytOakmeter projects.
