Reproductive Material

Our understanding of the genetic variation of forest trees and its dynamics is rapidly increasing. The glacial eras, postglacial migration and human transfer of reproductive material had deep impacts on genetic variation patterns of European forest trees. The genetic basis of variation at adaptive traits and traits of economic importance is currently investigated by molecular genetic approaches eventually leading to a better understanding of the functional importance of intraspecific variation for forest ecosystems. Important applications of forest genetic research including breeding, conservation and adaptation to changing environments are briefly described based on current fields of research. The establishment and observation of field trials, complemented by a molecular investigation of variation patterns in genes coding for adaptive traits, continues to be a main field of research. The potential for the use of transgenic trees is regarded as low in central Europe. The origin of forest reproductive material is routinely tested based on genetic markers in Germany. Forest genetics contributes to the protection of natural resources by the development and implementation of methods to conserve forest genetic resources. In addition, molecular genetic tools are developed to test the origin of wood and wood products and to identify illegally traded wood; first encouraging results have been obtained. Evolutionary processes must not be neglected within the context of adaptation to global change. The development of strategies to mitigate climate change effects on forests in central Europe should consider the genetic variation of tree species by the promotion of adaptive potentials. The current knowledge does not allow to propose long-distance seed transfer from south to north as a universal approach to promote adaptation to climate warming in Europe.

Wide Range

Climate change is projected to lead to a major reorganization of our forests. For example, higher annual mean temperatures, longer growth seasons and drier summers are predicted for many parts of central and southern Europe, and in North America. In order to understand the genetic adaptation to climate change we need a better understanding of the genetic regulation of key traits involved in tolerance of water and temperature stress. Oaks (Quercus spp.) are excellent model species to study the adaptation of forest trees to changing environments. They show a wide geographic distribution in Europe and in North America as dominant tree species in many forests growing under a wide range of climatic and edaphic conditions. With the availability of a growing amount of functional and expressional candidate genes we are now able to test the functional importance of genes by associating nucleotide variation in these genes with phenotypic variation in adaptive traits in segregating or natural populations. Studies trying to associate genetic variation with phenotypic variation in adaptive traits can be performed in full-sib families derived from controlled crosses (Quantitative Trait Loci [QTL] mapping) or in natural populations (association mapping). For several important adaptive traits QTL were mapped, the underlying genes have to be tested in natural populations. A future objective is to test whether genes that underlie phenotypic variation in adaptive traits are involved in local genetic adaptation and viability selection at the seedling stage, linked to reciprocal transplant experiments in order to assess the performance over climatic gradients.
