Abstract: | In addition to the extensive improvement programmes within fruitorchards and forest stands, considerable momentum is being generatedin the application of genetic manipulation strategies to a varietyof woody species. Several transformation approaches have beenadopted for the production of transgenic trees. These includeAgrobacterium-mediated gene delivery, chemical and/or electricalstimulated uptake of DNA into protoplasts, and the use of thenewer technology of high velocity bombardment of plant tissueswith DNA-coated particles. Transformation offers advantagesover other genetic manipulation techniques, such as somatichybridization, in that it allows the directed improvement oftrees with minimum disruption of the genetic integrity of anelite genome. The information presented here is a comprehensivereview of transformation in woody plants. Many of the advanceshave been made in this area during the last five years. Key words: Woody species, transformation, Agrobacterium, direct gene transfer |
