Abstract
The invention relates to the use of a modified Agrobacterium to deliver proteins directly to plant cells. Proteins of interest are delivered to the plant host in the form of a fusion protein with the Agrobacterium virulence 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.
