title: Two sequence classes of kinetoplastid 5S ribosomal RNA gene revealed among bodonid spliced leader RNA gene arrays.
abstract: The spliced leader RNA genes of Bodo saltans, Cryptobia helicis and Dimastigella trypaniformis were analyzed as molecular markers for additional taxa within the suborder Bodonina. The non-transcribed spacer regions were distinctive for each organism, and 5S rRNA genes were present in Bodo and Dimastigella but not in C. helicis. Two sequence classes of 5S rRNA were evident from analysis of the bodonid genes. The two classes of 5S rRNA genes were found in other Kinetoplastids independent of co-localization with the spliced leader RNA gene.
