Abstract

Experiments on genetic reconstitution of tobacco cells by fusion, of mesophyll protoplasts and enucleated cell fragments (cytoplast) was carried out. Technology of electrofusion of preselected pairs protoplast + cytoplast followed by individual culturing of fusion products in microdroplets of culture medium was utilized. After fusion of cells of the plastom chlorophyll-deficient mutant with cytoplasts containing 7–20 wild-type chloroplasts, in all cases plant regenerants have been obtained. In all clones tested, part of regenerates were variegated plants thus indicating presence of cytoplasmic genes of both parental sources.
