Sequence homology was found between the external transcribed spacer and the terminal non-transcribed spacer of Physarum polycephalum rDNA. The homologous sequences were located 2kb upstream from the 19S rRRA gene and 0.3kb downstream from 26S rRNA gene, respectively, and were arranged in a direct repeat manner. Sequence analyses showed that the direct repeats con sisted of two parts: one was sequences of about l3Obp which showed over 90% sequence homology with each other. The other consisted mainly of many tandem repeats of a 50̃52bp unit. The direct repeat-rRNA genes-direct repeat unit was found to be flanked by short direct repetitious sequences. Based on these findings, the significance of the direct repeat is discussed in terms of evolution of rDNA.

N2 - Sequence homology was found between the external transcribed spacer and the terminal non-transcribed spacer of Physarum polycephalum rDNA. The homologous sequences were located 2kb upstream from the 19S rRRA gene and 0.3kb downstream from 26S rRNA gene, respectively, and were arranged in a direct repeat manner. Sequence analyses showed that the direct repeats con sisted of two parts: one was sequences of about l3Obp which showed over 90% sequence homology with each other. The other consisted mainly of many tandem repeats of a 50̃52bp unit. The direct repeat-rRNA genes-direct repeat unit was found to be flanked by short direct repetitious sequences.
