      abstract     = {Douglas fir (Pseudotsuga menziesii) is a conifer species
                      that stores large amounts of terpenoids, mainly
                      monoterpenoids in resin ducts of various tissues. The
                      effects of drought on stored leaf terpenoid concentrations
                      in trees are scarcely studied and published data are
                      partially controversial, since reduced, unaffected or
                      elevated terpenoid contents due to drought have been
                      reported. Even less is known on the effect of drought on
                      root terpenoids. In the present work, we investigated the
                      effect of reduced water availability on the terpenoid
                      content in roots and needles of Douglas fir seedlings. Two
                      contrasting Douglas fir provenances were studied: an
                      interior provenance (var. glauca) with assumed higher
                      drought resistance, and a coastal provenance (var.
                      menziesii) with assumed lower drought resistance. We tested
                      the hypothesis that both provenances show specific patterns
                      of stored terpenoids and that the patterns will change in
                      response to drought in both, needles and roots. We further
                      expected stronger changes in the less drought tolerant
                      coastal provenance. For this purpose, we performed an
                      experiment under controlled conditions, in which the trees
                      were exposed to moderate and severe drought stress.
                      According to our expectations, the study revealed clear
                      provenance-specific terpenoid patterns in needles. However,
                      such patterns were not detected in the roots. Drought
                      slightly increased the needle terpenoid contents of the
                      coastal but not of the interior provenance. We also observed
                      increased terpenoid abundance mainly in roots of the
                      moderately stressed coastal provenance. Overall, from the
                      observed provenance-specific reactions with increased
                      terpenoid levels in trees of the coastal origin in response
                      to drought, we conclude on functions of terpenoids for
                      abiotic stress tolerance that might be fulfilled by other,
                      constitutively expressed mechanisms in drought-adapted
                      interior provenances.},
