摘要:
Compositions and methods for modulating cell cycle and cell proliferation are provided. Additionally the compositions find use in enhancing disease resistance and increasing transformation efficiency in plants. The method involves transforming a plant with a sense or antisense prohibitin sequence. The prohibitin sequence acts to regulate cell division in the plant cell. Transformed plants, plant cells, tissues, and seed are also provided having enhanced disease resistance.

摘要:
The invention provides improved plant transformation methods. In particular the method provides increased transformation freequency, especially in recalcitrant plants. The method comprises stably transforming a target cell with at least one polynucleotide of interest. The target cell has been previously transformed to stimulate growth of the cell and has gone through at least one cell division.

摘要:
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.
