aberrant plastid ribosomal RNA gene cluster in the root parasite Conopholis americana

The plastid ribosomal RNA (rRNA) operon of the achlorophyllous root parasite Conopholis americana was completely sequenced. Full-length rRNA genes are retained in the gene cluster, but significant divergence has occurred in the 16S, 23S and 5S genes. Both the 16S-23S intergenic spacer and the 4.5S-5...

Zusammenfassung:The plastid ribosomal RNA (rRNA) operon of the achlorophyllous root parasite Conopholis americana was completely sequenced. Full-length rRNA genes are retained in the gene cluster, but significant divergence has occurred in the 16S, 23S and 5S genes. Both the 16S-23S intergenic spacer and the 4.5S-5S intergenic spacer have suffered substantial deletions, including the two tRNA genes typically found in prokaryotic and plastid 16S-23S spacers.
