Abstract

Sodium butyrate at 4 mM and above blocked cell proliferation in root meristems of Allium cepa L. bulbs. Cytophotometric determinations in asynchronously growing cells, as well as cycle kinetics in synchronous binucleate cells. indicated that blocking took place at mid-G1 and at, or close to, the S/G2 border. Cell progression through S phase and mitosis was little affected. The cell cycle blockage induced by 6 mM butyrate was reversible when the drug was applied for periods of time not exceeding 12 h. Butyrate did not affect nucleic acid and protein synthesis activities, though its action on the cell cycle ressembled that produced by translation inhibitors.
