Zygote gene expression and plasmodial development in Didymium iridis A Thesis presented in Partial fulfillment of the Requirements for the Degree of Master of Biology By Sean Schaefer 2019 Advisor: Dr. Margaret Silliker Department of Biological Sciences College of Liberal Arts and Sciences DePaul University Chicago, IL Abstract: Didymium iridis is a cosmopolitan species of plasmodial slime mold consisting of two distinct life stages. Haploid amoebae and diploid plasmodia feed on microscopic organisms such as bacteria and fungi through phagocytosis. Sexually compatible haploid amoebae act as gametes which when fused embark on an irreversible developmental change resulting in a diploid zygote. The zygote can undergo closed mitosis resulting in a multinucleated plasmodium. Little is known about changes in gene expression during this developmental transition. Our principal goal in this study was to provide a comprehensive list of genes likely to be involved in plasmodial development. -
Myxomycetes NMW 2012Orange, Updated KS 2017.Docx
Myxomycete (Slime Mould) Collection Amgueddfa Cymru-National Museum Wales (NMW) Alan Orange (2012), updated by Katherine Slade (2017) Myxomycetes (true or plasmodial slime moulds) belong to the Eumycetozoa, within the Amoebozoa, a group of eukaryotes that are basal to a clade containing animals and fungi. Thus although they have traditionally been studied by mycologists they are distant from the true fungi. Arrangement & Nomenclature Slime Mould specimens in NMW are arranged in alphabetical order of the currently accepted name (as of 2012). Names used on specimen packets that are now synonyms are cross referenced in the list below. The collection currently contains 157 Myxomycete species. Specimens are mostly from Britain, with a few from other parts of Europe or from North America. The current standard work for identification of the British species is: Ing, B. 1999. The Myxomycetes of Britain and Ireland. An Identification Handbook. Slough: Richmond Publishing Co. Ltd. Nomenclature follows the online database of Slime Mould names at www.eumycetozoa.com (accessed 2012). This database is largely in line with Ing (1999). Preservation The feeding stage is a multinucleate motile mass known as a plasmodium. The fruiting stage is a dry, fungus-like structure containing abundant spores. Mature fruiting bodies of Myxomycetes can be collected and dried, and with few exceptions (such as Ceratiomyxa) they preserve well. Plasmodia cannot be preserved, but it is useful to record the colour if possible. Semi-mature fruiting bodies may continue to mature if collected with the substrate and kept in a cool moist chamber. Collected plasmodia are unlikely to fruit. Specimens are stored in boxes to prevent crushing; labels should not be allowed to touch the specimen. -

To facilitate this, we surveyed contrasting plant associations of an upland boreal forest (in British Columbia, Canada) to explore the association of soil productivity with cryptogam distribution and diversity. Total terrestrial cryptogam richness of the study sites (19 plots of 0.15 ha each) was 148 taxa, with 47 mosses, 23 liverworts, and 78 lichens. Soil productivity was strongly related to the distribution of cryptogams by guild (i.e. lichen species richness declined with productivity, while moss and liverwort richness increased) and substrate (i.e. species richness on forest floor and cobbles declined with productivity as species richness increased on coarse woody debris). Generalists comprised only 15% of the cryptogam community by species, and mesotrophic sites lacked some of the species adapted to the dry-poor or moist-rich ends of the producitivity spectrum. -

How- ever, biocrusts, as cryptogamic covers, inhabit some of these areas and provide essential ecological functions, but, nevertheless, they remain poorly described. Here, we applied high-throughput sequencing (HTS) and targeted four groups of microorganisms: bacteria, cyanobacteria, fungi and other eukaryotes. The sequencing of the 16S rRNA gene revealed the dominance of Proteobacteria, Cyanobacteria and Actinobacteria. Additionally, we applied yanobacteria-specific primers for a detailed assessment of the cyanobacterial community, which was dominated by members of the filamentous orders Synechococcales and Oscillatoriales. Furthermore, the majority of reads in the studied biocrusts obtained by sequencing of the 18S rRNA gene belonged to eukaryotic microalgae. In addition, sequencing of the internal rDNA transcribed spacer region (ITS) showed the dominance Citation: Pushkareva, E.; Sommer, V.; of Ascomycota within the fungal community.

Slime Moulds
Queen’s University Biological Station Species List: Slime Molds The current list has been compiled by Richard Aaron, a naturalist and educator from Toronto, who has been running the Fabulous Fall Fungi workshop at QUBS between 2009 and 2019. Dr. Ivy Schoepf, QUBS Research Coordinator, edited the list in 2020 to include full taxonomy and information regarding species’ status using resources from The Natural Heritage Information Centre (April 2018) and The IUCN Red List of Threatened Species (February 2018); iNaturalist and GBIF. Contact Ivy to report any errors, omissions and/or new sightings. Based on the aforementioned criteria we can expect to find a total of 33 species of slime molds (kingdom: Protozoa, phylum: Mycetozoa) present at QUBS. Species are Figure 1. One of the most commonly encountered reported using their full taxonomy; common slime mold at QUBS is the Dog Vomit Slime Mold (Fuligo septica).

Various problems in recording myxomycetes and analysis of their diversity are discussed by the examples taken from tundra, boreal, and arid areas of Russia and Kazakhstan. Recent advances in inventory of some regions of these areas are summarised. A rapid technique of moist chamber cultures can be used to obtain quantitative estimates of myxomycete species diversity and species abundance. Substrate sampling and species isolation by the moist chamber technique are indispensable for myxomycete inventory, measurement of species richness, and species abundance. General principles for the analysis of myxomycete diversity are discussed. Key words: slime moulds, Mycetozoa, Myxomycetes, biodiversity, ecology, distribu- tion, habitats Introduction decay (Madelin, 1984).

Mycosphere 6(3), 356–384, doi 10.5943/mycosphere/6/3/11 Abstract A total of 299 substrate samples collected throughout the Sultanate of Oman were analyzed for myxomycetes and myxomycete-like organisms (MMLO) with a combined approach, preparing one moist chamber culture and one agar culture for each sample. We recovered 8 forms of Myxobacteria, 2 sorocarpic amoebae (Acrasids), 19 known and 6 unknown taxa of protostelioid amoebae (Protostelids), and 50 species of Myxomycetes. Moist chambers and agar cultures completed each other. No method alone can detect the whole diversity of myxomycetes as the most species-rich group of MMLO. A significant overlap between the two methods was observed only for Myxobacteria and some myxomycetes with small sporocarps.
