RESUMO

The mitochondrial genome of the chytrid Blastocladiella emersonii was sequenced and annotated, revealing the complete set of oxidative phosphorylation genes and tRNAs/rRNAs necessary for the translation process. Phylogenetic reconstructions reinforce the proposal of the new phylum Blastocladiomycota. Evidences of gene duplication due to inserted elements suggest shared susceptibility to gene invasion/exchange between chytrids and zygomycetes. The gene content of B. emersonii is very similar to Allomyces macrogynus but the content of intronic and changeable elements is much lower suggesting a stronger resistance to this kind of exchange. In addition, a total of 401 potential nuclear transcripts encoding mitochondrial proteins were obtained after B. emersonii EST database scanning using Saccharomyces cerevisiae, Homo sapiens and Arabidopsis thaliana data as probes and TargetP tool to find N-terminal mitochondrial signal in translated sequences.

RESUMO

A new species of fungus belonging to the lethal genus Coelomomyces, C. neotropicus, is described and illustrated. It was found parasitizing larvae of two species of Culicidae, Culex pilosus and Aedes sp., in a lowland tropical wet forest swamp in northeast Costa Rica.
