    Area of Science:

    • Plant Biotechnology
    • Cell Biology
    • Electrofusion Techniques

    Background:

    • Plant protoplast fusion is crucial for genetic modification and breeding.
    • Traditional methods can be inefficient or damaging to cells.

    Purpose of the Study:

    • To develop an efficient and precise method for fusing single plant protoplasts.
    • To investigate the use of dielectrophoresis and a single DC pulse for Nicotiana tabacum protoplast fusion.

    Main Methods:

    • Isolation of single mesophyll protoplasts from Nicotiana tabacum cv. xanthi.
    • Alignment of two protoplasts using dielectrophoresis in a microdroplet with platinum electrodes.
    • Induction of fusion via a single square DC pulse.

    Main Results:

    • Successful alignment of single protoplasts using dielectrophoresis.
    • Induction of protoplast fusion with a single DC pulse of approximately 1.5 KV X cm-1.

    Conclusions:

    • Dielectrophoresis combined with a single DC pulse is an effective method for plant protoplast electrofusion.
    • This technique offers a precise approach for single-cell fusion in Nicotiana tabacum, with potential applications in plant science.
