protoplast fusion
protoplast fusion[′prōd·ə‚plast ‚fyü·zhən] (genetics) A technique by which two protoplasts are fused to form hybrid cells that can grow into mature hybrid organisms; usually performed on plants. protoplast fusion
protoplast fusion the joining together of two or more PROTOPLASTS. Often the presence of polyethylene glycol or electric fields will enhance the frequency of fusion. In the fusion unit the DNA from the component cells may undergo RECOMBINATION. This method is useful in GENETIC ENGINEERING. It may allow the exchange of DNA between unrelated ORGANISMS if they are capable of undergoing protoplast fusion. |
