Physarales is of particular interest since the two best-studied myxomycete species, Physarum polycephalumand Didymium iridis, belong to this order and are currently subjected to whole genome and transcriptome analyses. The two genes were found to very homologous with regions of E. coli and indicate a link between these, which are eukaryote specific, and the larger prokaryote rRNA gene. If there is insufficient nutrients, microplasmodia can form Spherules, a dormant form. 10. Although they used to be classified as fungi, slime molds aren’t really molds at all. Directions are given for: acquiring the organism; activating it; observing its life cycle; and viewing protoplasmic streaming. This is where it starts to sporulate (produce spores) and these spores eventually rupture from the cell leaving them exposed for wind and rain to distribute. Sporulation competence of slow desiccation-induced sclerotia. (n.d.). 80 no. Plasmodium: the diploid vegetative state that migrates around to find food.

Sclerotia: a dormant stage formed in poor growing conditions. Background Myxomycetes (plasmodial slime molds) are eukaryotic microorganisms that according to Olive [1] represent one of four main groups of slime molds (Mycetozoans). Small plasmodia: can grow large like number 1 if there is a suitable food source. In moving, the plasmodium may move along many fronts that are connected by veins. Olive defines the Mycetozoa as consisting of three distinct groups ().The true or plasmodial slime molds (Myxogastria—e.g., Physarum polycephalum) are amoeboflagellates, most of which develop into large, reticulate plasmodia with >10 4 synchronously dividing nuclei. Subclass: Endosporeae Phylum. Scale bar ~0.5 cm. Species: Physarum polycephalum Also, while widely considered to be a lower eukaryote, study of aminoacyl-tRNAs has shown that P. polycephalum has patterns of codon recognition that are more like higher plants and animals, and lower fungi. So this slime molds name really means "many headed slime."  Ridgway B. E, Durham C. H. A. J Cell Biol. It acts like an animal but appears to be more of a fungus. With light stimulation the slime mold begins to retract and can eventually lead to a dormant stage. 1. Physarum polycephalum Schwein. These include periodic events of the mitotic cycle in Physarum polycephalum. Physarum compressum. The entire genome has yet to be sequenced, but there have been some parts that have revealed a good deal about this organism, such as the 26S and 5.8S rRNA genes. Since 2008 Heather Barnett has been working with the true slime mould, Physarum polycephalum, observing and influencing its growth patterns, navigational abilities and seemingly human behaviours. With a tendency to be very easy to cultivate in the lab, it is used to study mitosis, streaming/cell motility (the movement), and basal forms of intelligence.
