摘要：

The Bodo caudatus mini-exon-derived RNA gene repeat has been isolated following PCR amplification. The DNA sequence of the mini-exon fits the trypanosomatid mini-exon consensus, supporting inclusion of Bodo in this group. The B. caudatus mini-exon repeat also contains the 5S ribosomal RNA gene, an organization found in the trypanosome T. rangeli and five genera of nematodes. Phylogenetic analysis of both mini-exon-derived RNA gene and 5S gene sequences show that the free-living B. caudatus is more closely related to the monogenetic Crithidia than the digenetic Trypanosoma. Similarity between the Euglena gracilis trans-spliced leader and trypanosomatid mini-exon sequences was also noted during these comparisons. © 1992.
