Occurrence of 9 homologous repeat units in the external spacer region of a nuclear maize rRNA gene unit.

Abstract:

:A 14 kb maize DNA fragment carrying nuclear rRNA genes and spacer regions was isolated and characterised by restriction enzyme mapping. A complete 3020 bp long external spacer region was sequenced and revealed 9 tandemly arranged 200 bp long repeat units with high homology. The repeat units lie upstream from two prominent S1 mapping signals. The sequence of a typical repeat unit is compared to a corresponding 130 bp long wheat repeat unit. The possible functional relevance of the repeat units is discussed.
