Lily cv. Harmony was inoculated with several Agrobacterium strains to
study its susceptibility to Agrobacterium infection and transformation
. Tumorous tissue formation on inoculated stem internodes of sterile-g
rown plantlets, as well as expression of a beta-glucuronidase marker g
ene interrupted by an intron in cells of inoculated stem nodes, indica
te that the monocotyledon Lilium is a host for Agrobacterium.
