TrophinOak – PhytOakMeter

TrophinOak and PhytOakMeter focus on biotic and abiotic interactions with the clonal Oak tree DF159 under laboratory, green house and field conditions. Transcriptomic and metagenomic analyses are coupled with traits and allocation analyses in order to better understand how this important forest tree with complex multitrophic interactions can adapt under a changing environment. The TrophinOak project started in 2010 at the Helmholtz- Centre for Environmental Research - UFZ under the financial support of the DFG.

Research focus


  • Impact of the endogenous rhythmic growth of Quercus robur DF159 on resource allocations during multitrophic interactions under controlled conditions.
  • Establishment of the OakContigDF159.1 reference library to study differential gene expression in Q. robur during biotic and abiotic interactions.


  • Annual out planting of the Q. robur DF159 in Bad Lauchstädt and Kreinitz since 2010 to monitor the impact of the site and the tree age on soil microorganism communities in relation to the oak development and biotic above-below interactions.
  • Out planting of Q. robur DF159 trees along a European geographic gradient and at a German local level under different land uses since 2013 to monitor the impact of climate change and land use management on the “soil - plant – interactor” complex.
