Abstract—
High-throughput sequencing of 16S rRNA genes was used to investigate the taxonomic diversity of the bacterial community inhabiting the fruiting bodies of the myxomycete Lycogala еpidendrum. Members of 31 bacterial genera belonging to six phyla were revealed. The phylum Proteobacteria predominated in the microbiome, with Pseudomonas and Luteibacter as predominant genera. Analysis of the taxonomic diversity of bacterial communities revealed significantly lower diversity in the L. epidendrum community, compared to those of brushwood and litter adjacent to the fruiting bodies. This is an indication of a selective role of the myxomycete fruiting body in respect to the phylum Proteobacteria and especially to the genera Pseudomonas and Luteibacter.
