Apple (
Malus
�
domestica
) is one of the most consumed fruit crops in the world. The major production areas are the temperate regions, however, because of its excellent storage capacity it is transported to distant markets covering the four corners of the earth. Transformation is a key to sustaining this demand—permitting the potential enhancement of existing cultivars as well as to investigate the development of new cultivars resistant to pest, disease, and storage problems that occur in the major production areas. In this paper we describe an efficient
Agrobacterium tumefaciens
-mediated transformation protocol that utilizes leaf tissues from in vitro grown plants. Shoot regeneration is selected with kanamycin using the selectable kanamycin phosphotransferase (APH(3)II) gene and the resulting transformants confirmed using the scorable
uidA
gene encoding the bacterial β-glucuronidase (GUS) enzyme via histochemical staining. Transformed shoots are propagated, rooted to create transgenic plants that are then introduced into soil, acclimatized and transferred to the greenhouse from where they are taken out into the orchard for field-testing.
