Stimulation of cell division by membrane-active agents
1973
Abstract Agents that decrease membrane stability (e.g. dimethyl sulfoxide, lysolecithin, sodium oleate, and short-chain alcohols) stimulate multinucleoid, serpentine filaments of Agmenellum quadruplicatum strains SN12 and SN29 to divide into cellular equivalents within approximately one generation time. Agents that increase membrane stability (e.g. long-chain alcohols) antagonize this timulation. Thus, the physical properties of the cell membrane appear to be involved in the regulation of cell division. These observations suggest that the invagination of the cell wall may be regulated by agents that interact with the plasma membrane and with enzymes involved in peptidoglycan synthesis.
