The aims of this study are to clarify the evolution of the controlling mechanism in the form of a simple leaf and the compound leaf of the vascular plant. We try to establish the transgenic strain using pteridophyte Asplenium australasicum. However, an effective transgenic strain was not made of establishment using Agrobacterium. We also tried to establishment of the transgenic strain by the electroporation method. As a result, it succeeded in the redifferentiation of the plant body from callus. However, the transgenic strain cannot been established yet. We want to be going to establish the transgenic strain of the pteridophyte in the future, and to clarify the control of a simple leaf and the compound leaf of vascular plant.
