Abstract: Methods for producing genetically modified plants, particularly woody plants, and most particularly plants of the Eucalyptus and Pinus species, involve transformation of target plant material with a desired genetic construct and regeneration of the transformed plant material using an adventitious shoot bud system. The methods provide a high transformation efficiency and substantially reduce the duration of the transformation and regeneration protocols. Stem segments of a target plant are transformed using Agrobacterium-mediated techniques, and adventitious shoot buds are regenerated from the Agrobacterium-infected stem segments. Preferred culture media, including selection media, and improved plant culture techniques are disclosed.
