Phylogenetic position of yeastlike endosymbionts of anobiid beetles
Article Abstract:
The yeastlike symbionts (YLS) Symbiotaphrina buchneri and S. kochii present in anobiid beetles are phylogenetically near the paraphyletic class Discomycetes and the order Lecanorales. The rRNA-encoding genes' nucleotide sequence shows that the YLS are euascomycetes and form a monophyletic group that is different from other yeast lineages. This indicates that the YLS should not be placed in the family Taphrinaceae. The YLS probably deviated from the filamentous fungi during the early radiation of euascomycetes and became endosymbionts of beetles.

Endosymbionts of ticks and their relationship to Wolbachia spp. and tick-borne pathogens of humans and animals
Article Abstract:
A study was conducted on the existence, phylogenetic position and internal distribution of endosymbiotic bacteria from Rhipicephalus sanguineus, Ixodes scapularis, Ornithodoros moubatta and Haemaphysalis longicornis. PCR assays show that Ixodes scapularis has symbiotic rickettsiae while the other specific-pathogen-free ticks posses eubacteria in their Malighian tubules and ovaries. Results also show that the symbionts in all four tick species are not related to Wolbachia.

Novel group within the kingdom Crenarchaeota from boreal forest soil
Article Abstract:
Nucleotide sequence and phylogenetic analyses reveals that the archaeal 16S rRNA sequences from forest soil belong to the domain Archaea and form a new cluster. The phylogenetic position of this cluster suggests that the sequences belong to the terrestrial low-temperature Crenarchaeota kingdom. PCR amplification techniques along with Archaea-specific primers containing mixed-population DNA help to analyse the gene sequence.
