A simple gene transfer method based on Agrobacterium-mediated transfor
mation of adventitious multiplication of Juneberry (Amelanchier laevis
L.) basal shoots is described. Evidence is presented for successful i
ntegration and expression of a transformed gene in greenhouse-grown tr
ansgenic plants. This method can transform woody perennials that are d
ifficult to regenerate from leaf disks, protoplasts, or other tissue c
ulture regimens.
