Genetic engineering has the potential to allow the selective improvement of individual traits in woody plants without the loss of any of the desired trait of the parental line. Using such techniques, we can overcome the difficulties associated with the breeding of long-lived perennials, which need to long time to produce progeny. The Forestry and Forest Products Research Institute (FFPRI) has succeeded in the largescale collection of 19,841 nonredundant Populus nigra full-length enriched cDNA clones by collaboration with the RIKEN Plant Science Center. And the FFPRI has also collected 10,464 nonredundant full-length enriched cDNA clones of Cryptomeria japonica male strobili. These cDNA resources are useful for the development of genetically modified trees. In this paper, I introduce recent advances in the development of genetically modified trees with enhanced productivity and environmental stress-tolerance. I also discuss the necessity of flowering control to prevent a risk of diffusion of recombinant genes in the field, and the availability of genetically modified trees for the prevention of global warming.
