摘要
The present invention provides an improved method for achieving stable integration of an exogenous DNA fragment in intact form into the genome of a eukaryotic cell, particularly a plant cell. The method comprises providing the exogenous DNA together with one or more proteins which promote integration of the exogenous DNA to the eukaryotic cell targeted for transformation, wherein the proteins are provided in the form of a chimeric gene or translatable RNA capable of expression in the eukaryotic cell. The method is particularly applied to plant cells to achieve stable integration of an exogenous DNA fragment bounded by T-DNA borders in intact form using integration-promoting proteins derived from Agrobacterium. Transgenic cultures, tissues and whole organisms, particularly transgenic plants, can be generated from cells transformed according to the method of the invention.
