Tomato transformation is conventionally performed using Agrobacterium tumefaciens-infected cotyledons. Here, we propose a simple procedure for tomato transformation, by which A. tumefaciens cells were smeared onto floral buds of a tomato plant using a paintbrush. Sufficient numbers of fruits were obtained from them, although the smearing of an excess number of A. tumefaciens cells led to an adverse effect on the plant growth. Progeny plants were screened by growth on a kanamycin-containing selection medium plate. The nptII gene was detected in 10 plants among 1,599 progenies. These transformants were derived from fruits other than those obtained from the smeared buds. This suggested that A. tumefaciens cells moved to the buds located near the smeared buds and caused the transformation event. Our findings suggest that this procedure can be used for the introduction of a foreign gene into plant cells.
