1. The microsporidian sex-related locus.
The microsporidian sex-related locus. (A) Differential interference contrast (DIC) and transmission electron microscopy (TEM) images of an E. cuniculi spore. A polar tube is everted from the spore. The spore contains a coiled polar tube. (B) sex-related loci observed for four different microsporidian species. The E. cuniculi and A. locustae genomes contain a syntenic region encompassing TPT (green), HMG (red), and RNA helicase (blue) genes similar to that observed at the zygomycete sex loci (Fig. 11). The E. cuniculi sex-related locus has an additional weak homology HMG gene (purple). All sex-related loci from the four different microsporidian species have a conserved hypothetical protein gene (yellow). Two other microsporidians, E. bieneusi and N. ceranae, have an unlinked RNA helicase gene. Only microsporidia and zygomycetes share the synteny of the TPT, HMG, and RNA helicase genes compared to other fungi for which complete genome sequences are available.
