Southern blotting of restriction endonuclease fragments of P. polycephalum DNA and hybridization to a cloned probe labelled by nick-translation indicate that there are only one or two copies of each H4 gene per haploid genome. A cloned homologous genomic probe was used to study the cellular abundance of H4 mRNA during the cell cycle. We report that the H4 mRNA is not only transcribed in S phase as previously described for other organisms but that transcription of the H4 gene also occurs at the end of G2 phase. Since no translation of the histone messenger was observed in G2 phase this suggests that the histone mRNA synthesized in G2 constitutes a pool of molecules in anticipation of the next S phase.
