Electrofusion-mediated transmission of cytoplasmic organelles through the in vitro fertilization process,fusion of sperm cells with synergids and central cells,and cell reconstitution in maize

Summary Fusion products were created by the electrofusion of single sperm cells with single synergids and central cells. The synergid was also fused with the sperm cell, occasionally in the presence of adhering second synergids, egg cells, and central cells. Single egg cells were fused with single sperm cells in the presence of adhering synergids and the central cell. Cytoplasmic organelles were transmitted through the fertilization process by electrofusion using cytoplasts of maize mesophyll cells. Cell reconstitution was achieved by fusion of one or two sperm cells with single enucleated protoplasts, thus creating a haploid or a diploid cell.
