Patent number: 6265638Abstract: Compositions and methods for the efficient co-transformation of a plant are provided. Novel compositions are Agrobacterium strains that have been engineered to comprise at least two binary vector plasmids in addition to a helper plasmid comprising the vir functions. Each of the binary vectors comprises its own T-DNA borders flanking a heterologous nucleotide sequence of interest. Methods of the invention comprise the use of these novel multiple-binary vector Agrobacterium strains to co-transform a plant. In this manner, heterologous nucleotide sequences of interest residing on different binary vectors can be independently introduced into the plant in a single transformation event and incorporated in the plant's nuclear DNA in an unlinked manner. The invention also provides for regenerated, fertile transgenic plants, transgenic seeds produced therefrom, and T1 and subsequent generations.Type: GrantFiled: September 28, 1999Date of Patent: July 24, 2001Assignee: Pioneer Hi-Bred International, Inc.Inventors: Dennis L.
