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, including of course the evaluation of all challenges and risks related to gene transfer methods. Compared with annual plants, especially in the field of agriculture, the work and the progress with transgenic trees is still in its infancy. Nevertheless, but often unnoticed by the scientific community, there are a few countries which already allow the commercial use of a restricted number of transgenic tree clones after different critical steps of approval. This and the ongoing improvement in transgenic research in trees led to the idea of preparing a summary of the present state of the art from different points of view. With the help of a number of authors directly or indirectly involved in tree transgenesis, this book was produced.
Biosafety of Forest Transgenic Trees
This book provides up-to-date information on the environmental impact of transgenic trees on genetically modified tree (GMT) communication strategy. It is useful to public/private organisations as well as to private and public research bodies and universities worldwide since it reports on the global status of GMT research and policy. A high number of genetically modified trees (GMTs) with altered or novel characteristics have been produced in the last 15 years. However, their very low public acceptance is a basic problem in their commercialization. Breeders anticipate economic and ecological benefits, like reduced product costs and less pressure on native forests, while opponents fear risks, such as unintended spread of GMTs. But what is true? To answer this question, the COST Action FP0905 focused on key aspects related to GMTs: (a) biological characterization; (b) assessment of possible environmental impacts; (c) socio-economic implications and public acceptance/concerns; (d) providing science-based information to communicate with the public.
Tree Biotechnology
Forest trees cover 30% of the earth's land surface, providing renewable fuel, wood, timber, shelter, fruits, leaves, bark, roots, and are source of medicinal products in addition to benefits such as carbon sequestration, water shed protection, and habitat for 1/3 of terrestrial species. However, the genetic analysis and breeding of trees has lagged
