      abstract     = {BackgroundLocal adaptation and phenotypic plasticity are
                      important components of plant responses to variations in
                      environmental conditions. While local adaptation has been
                      widely studied in trees, little is known about plasticity of
                      gene expression in adult trees in response to ever changing
                      environmental conditions in natural habitats. Here we
                      investigate plasticity of gene expression in needle tissue
                      between two Douglas-fir provenances represented by 25 adult
                      trees using deep RNA sequencing (RNA-Seq).ResultsUsing
                      linear mixed models we investigated the effect of
                      temperature, soil water availability and photoperiod on the
                      abundance of 59189 detected transcripts. Expression of more
                      than 80 $\%$ of all identified transcripts revealed a
                      response to variations in environmental conditions in the
                      field. GO term overrepresentation analysis revealed gene
                      expression responses to temperature, soil water availability
                      and photoperiod that are highly conserved among many plant
                      taxa. However, expression differences between the two
                      Douglas-fir provenances were rather small compared to the
                      expression differences observed between individual trees.
                      Although the effect of environment on global transcript
                      expression was high, the observed genotype by environment
                      (GxE) interaction of gene expression was surprisingly low,
                      since only 21 of all detected transcripts showed a GxE
                      interaction.ConclusionsThe majority of the transcriptome
                      responses in plant leaf tissue is driven by variations in
                      environmental conditions. The small variation between
                      individuals and populations suggests strong conservation of
                      this response within Douglas-fir. Therefore we conclude that
                      plastic transcriptome responses to variations in
                      environmental conditions are only weakly affected by local
                      adaptation in Douglas-fir.},
