Onset of mitosis after cell cycle blockage induced by cycloheximide in root tip cells

Summary The cells in S-phase at the time of a short treatment with cycloheximide, inducing reversible arrest of the cell cycle, enter mitosis before those in G₂ and are divided into 2 subpopulations when cell proliferation resumes.This work was supported by AI 031871 from the Centre National de la Recherche Scientifique and the University René Descartes, Paris.
