Breeding of forest species is limited by intrinsic characteristics such as individual’s height and long life cycle. Plant genetic transformation, the integration of known foreign genes into the plant genome, represents a less time consuming alternative for the recovery of forest species with desirable traits. This technology has contributed to plant breeding programs by facilitating the recovery of genotypes containing novel exciting traits of agricultural importance. Many of them including resistance to insect pests, improvement of wood quality and biomass production, and tolerance to herbicides have been introduced in forest species such as poplar, eucalyptus and pine trees using this technology. This review highlights current transformation methods, and illustrates the importance of finally defining the most important traits that have already been introduced into these valuable species.
