A continuous development in plant biotechnology including gene technology has been observable during the past 20 years. Different methods elaborated with model plants were also applied to forest trees on a larger scale. Whereas in the beginning the meaning of the term "plant biotechnology" embraced a wide variety of meanings like, e. g., regeneration of plantlets via tissue culture, embryo rescue, somatic embryogenesis and gene transfer, the focus of this term has changed more and more. Nowadays, it is the transfer of genes which comes into mind when plant biotechnology is discussed,...

This unique single source integrates tree transgenesis, functional genomics, and structural genomics to present, for the first time, a unified approach to research on the molecular biology of forest trees.

We describe the establishment of an activation tagging system in poplar based upon the maize Ac/Ds transposable element system. Transgenic poplar plants were obtained carrying either one or two of the above mentioned constructs [ Following induction of the GIP promoter only a weak transposase signal could be detected in RT- PCR experiments. Mobility of the ATDs activation construct could not be confirmed in the GIP system. [ An Activation Tagging experiment was initiated using eight different double transgenic lines. A few putative variants could be obtained revealing deficiency in...
