show Abstracthide AbstractThe common oak (Quercus robur L.) expresses an endogenous rhythmic growth with alternating shoot and root flushes. To tackle mechanisms behind this pattern, we performed controlled microcosm experiments using microcuttings of the Q. robur clone DF159. In addition, we tested the effect of inoculation with the ectomycorrhizal fungus Piloderma croceum on the rhythmic growth pattern. Illumina RNA sequencing served to profile transcripts in leaves and lateral roots. This work was part of the research program TrophinOak (www.trophinoak.de) of seven research groups working with oak microcuttings to study gene expression and resource allocation in multitrophic interactions, funded by the DFG, German Research Foundation.
