DNA synthesis and cytoplasmic differentiation in tapetal cells of normal and cytoplasmically male sterile lines of Petunia hybrida.
A new method is described by which tapetal cells may be isolated from anthers of cytoplasmic male sterile (CMS) and fertile lines of Petunia hybrida. Using a combination of stereometry and Feulgen densitometry it has been possible to chart DNA synthesis and nuclear division with great precision within these cells. Results are presented which show CMS lines both to synthesize far less DNA than the fertiles and also to undergo less cell division. These differences in DNA kinetics and cytokinesi...Expand abstract
