Abstract
A mutant of Chlamydomonas reinhardii which lacks a cell wall was fused with Daucus carota protoplasts using polyethylene glycol and the resulting fusion products were cultured. Fusion involved integration of Chlamydomonas and carrot plasma membranes and the release of algal organelles into the carrot cytoplasm. Chlamydomonas basal bodies, nuclei and chloroplasts were frequently observed in the fusion products. Cultured fusion products regenerated cell walls and divided; most Chlamydomonas organelles degenerated during culture but chloroplasts were still recognizable in the carrot cytoplasm after 10.
