Abstract: | Tobacco mesophyll protoplasts were fused with protoplasts fromcultured cells by electric fusion. When the fusion productswere cultured for 2 d, chloroplast division was observed inthe heterokaryocytes under fluorescence microscopy after stainingwith DAPI, while such chloroplast division was not observedwhen mesophyll protoplasts alone were cultured in the same condition. 3Permanent address: Research Institute of House Food IndustryCo.
