【 摘 要 】

The genetic transformation which consists in a controlled introduction of a gene in the genome of a receive cell and its subsequent expression, assumes additional significance, giving new perspectives to genetic improvement of the forest species, extending and available new genes with desirable characteristics, to be incorporated in a smaller period of time. Through the strategies Agrobacterium and bioballistic, transgenic plants had already been obtained showing higher biomass production, better wood quality, resistance to some insects, tolerance to herbicides, among other desirable characteristics, showing the relevance of these tools to the forest industry. This revision points out in a summarized way, the importance of establishing an efficient in vitro regeneration system, the strategies used in the genetic transformations of forestry species and some agroforestry characteristics that were previously incorporated in these species.
