The polycation mediated attachment of purified tritiated DNA to plant protoplasts has been measured by quantitative microautoradiography. The automated grain counting technique used, also provides information on the cell cycle stage of individual protoplasts, which circumvents the need to
Protoplasts isolated from rapidly dividing cell suspension cultures of either Nicotiana sylvestris or tumor derived cultures of Crepis capillaris were fused by PEG or liposome treatments to form homokaryons. Analysis of binucleates by Feulgen microspectrophotometry, and autoradiography, has revealed
