The efficient transformation of plants with large
DNA
molecules containing a set of useful genes would provide vast possibilities for the genetic improvement of agricultural as well as nonagricultural plants. The development of the bioactive beads (BABs) transformation method has proven useful for introduction of large DNA molecules into plant cells. In this chapter, the BABs transformation method used for the transformation of a 100-kb BAC DNA construct containing wheat genes into rice will be presented. Furthermore, the improved production method for BABs will be described. With the conventional method for producing BABs, the bead size varies, and the larger beads tend to carry fewer DNA molecules than the smaller beads. Thus, in order to facilitate the preparation of BABs with more uniform sizes, a simple set-up �composed of a sine wave sound generator and microsyringe pump was fabricated. Using this bead-maker set-up, uniform and smaller beads could be produced which enhance the transformation efficiency.
