Protocols for the production and transformation of grapevine embryogenic cultures are described. Embryogenic cultures are initiated from leaves or stamens and pistils and transformed with
Agrobacterium
containing an enhanced green fluorescent protein/neomycin phosphotransferase II (e
gfp
/
nptII
) fusion gene. Cultures are transferred to induction medium in the dark for callus formation and proliferation. Resulting cultures are transferred to somatic embryo development medium to induce secondary embryogenesis and formation of transgenic somatic embryos. Transgenic embryos identified on the basis on GFP fluorescence and kanamycin resistance are transferred to germination medium to regenerate transgenic plants. The presence of transgenes in independent plant lines is confirmed by
PCR
.
