Molecular diversity of myxomycetes near Siegen (Germany)

Genetic variations of myxomycetes were seldom studied. Different probes were collected in the general vicinity of the city of Siegen, Germany, with a special focus on Fuligo septica. Three different habitats around Siegen were screened for myxomycetes. Fuligo septica var. flava was examined for intraspecific variation using DNA sequence analysis. A 142 bp region of the mitochondrial small subunit was analyzed. Although the sequence analysis did not strictly assign individuals to separate groups related to their geographical regions. Herewith I present the first molecular genetic tree revealing intraspecific variation that occurs within the morphospecies F. septica. ► Genetic variability of myxomycetes. ► A 142 bp fragment of the mtDNA was sequenced and differences are shown. ► Three groups of mtDNA could distinguish in these vicinity regions.
