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.

Methods for enhancing plant transformation frequencies

The invention relates to compositions and methods and for genetically transforming plants. Compositions comprising transformation-enhancing agents and methods of use are provided. The methods involve administering an effective amount of a transformation-enhancing agent to a plant. The compositions and methods of the invention find use in improving transformation efficiency and increasing the embryogenic response of callus.
