The invention relates to the use of a modifiedto deliver proteins directly to plant cells. Proteins of interest are delivered to the plant host in the form of a fusion protein with thevirulence protein VirF. Nucleotide sequences encoding such fusion proteins of VirF and a protein of interest are provided. Also provided are bacteria modified to comprise such fusion proteins of VirF and a protein of interest. Methods of introducing such fusion proteins into a plant host are provided. The invention finds use in facilitating plant transformation and particularly in the bio-engineering of desirable traits into crop plants.

Method for delivery of proteins to plant cells

The invention provides novel methods of using viral replicase polypeptides and polynucleotides. Included are methods for increasing transformation frequencies, increasing crop yield, providing a positive growth advantage, modulating cell division, transiently modulating cell division, and for providing a means of positive selection.

Methods of using viral replicase polynucleotides and polypeptides

The invention provides isolated polynucleotides and their encoded proteins that are involved in cell cycle regulation. The invention further provides vectors, recombinant expression cassettes, host cells, transgenic plants, and antibody compositions. The present invention provides methods and compositions relating to altering cell cycle protein content and/or composition of plants.
