Abstract
The complete DNA sequences data of the ribosomal RNA (rRNA) genes of the microsporidian type
species, Nosema spodopterae, and N. bombycis. Sequences for the N. bombycis rRNA large subunit
gene (LSUrRNA: 2497 bp, GenBank Accession No. AY211393), the internal transcribed spacer (ITS:
179 bp, GenBank Accession No. AY211394), the small subunit gene (SSUrRNA: 1232 bp), intergenic
spacer (IGS: 279 bp), and 5S region (114 bp) are also given, and the secondary structure of the large
subunit is discussed. The unusual organization of the N. bombycis rRNA genes, LSUrRNA- ITSSSUrRNA-
IGS -5S, is the first found in microsporidia. This novel arrangement, in which the LSU is
located at 5' end of the SSU, is the reverse of the organizational sequence (i.e., SSU-ITS-LSU) found
in all previously reported microsporidian rRNAs, including Nosema apis. This unique character in the
type species may have taxonomic implications for the members of the genus Nosema. This result has
been published in the journal, Fungal Genetic and Biology 41, 473-481 pp.
