The order Physarales is of special interest since it contains the two best-studied myxomycete species at the biochemical and molecular levels (Physarum polycephalum and Didymium iridis) [6, 18]. Each P. polycephalum can merge with the individuals surrounding it, forming a super-sized cell that’s capable of reaching a metre in length that can slowly creep towards nearby food (usually fungal spores and bacteria). Fusion between two swarm cells or myxamoebae followed by karyogamy results in … obrusseum (Berk. The exon–intron organization of its genes, examined in this paper, exhibits features apparently unique to this organism, features typical for the evolutionarily old (and usually small-genomed) taxa, as well as those characteristic for the more advanced (and large-genomed) ones.
