Plasmodial slime moulds (myxomycetes) in Swedish and Nordic folk biology [PDF]
Journal of Ethnobiology and EthnomedicineBackground Folk biology commonly contains knowledge of many more taxa than those of immediate economic importance. Species with little or no practical use are, however, often overlooked by ethnobiological research.

Effective mixing due to oscillatory laminar flow in tubular networks of plasmodial slime moulds
New Journal of Physics, 2020 The plasmodium of the unicellular slime mould Physarum polycephalum forms an extended vascular network in which protoplasm is transported through the giant cell due to peristaltic pumping. The flow in the veins is always parabolic and it performs shuttle

Diet and mitonuclear haplotype interactions affect growth rate in a slime mould. [PDF]
Ecol Evol, 2023 Three‐way interactions between mitochondrial, nuclear haplotypes and dietary P:C ratios affected the slime mould's surface area of growth but not biomass. Our findings have broad implications for our understanding of the effect of mitonuclear interactions on trait expression across diverse eukaryotic lineages.

Two-gene phylogeny of bright-spored Myxomycetes (slime moulds, superorder Lucisporidia). [PDF]
PLoS ONE, 2013 Myxomycetes, or plasmodial slime-moulds, are one of the largest groups in phylum Amoebozoa. Nonetheless, only ∼10% are in the database for the small subunit (SSU) ribosomal RNA gene, the most widely used gene for phylogenetics and barcoding.

The Occurrence of Myxomycete Communities in Taxodium distichum Forests: Influence of Substrates and Seasons [PDF]
MicroorganismsMyxomycete communities in Taxodium distichum forests and the influence of substrates and seasons on myxomycete diversity were studied. In total, 80 substrates (40 living barks and 40 litters) were collected from the sample site in winter, spring, summer ...

Applicability of Redirecting Artemisinins for New Targets
Global Challenges, Volume 7, Issue 12, December 2023., 2023 Repurposing of drugs has great practical appeal. However, a systematic approach is essential. Here, artemisinins (ARTS) are used to illustrate some considerations that are critical in this process. Several mechanisms of action are suggested for ARTS, among which only a few are successfully examined in vivo, mainly the induction of oxidant stress and ...

Biological Reviews, Volume 98, Issue 6, Page 2188-2209, December 2023., 2023 ABSTRACT Multicellularity evolved multiple times in the history of life, with most reviewers agreeing that it appeared at least 20 times in eukaryotes. However, a specific list of multicellular eukaryotes with clear criteria for inclusion has not yet been published.

On the evolution of epigenetics via exaptation: A developmental systems perspective
Annals of the New York Academy of Sciences, Volume 1529, Issue 1, Page 21-32, November 2023., 2023 Abstract Evolution and development are interrelated processes influenced by genomic, epigenetic, and environmental factors. Epigenetic processes serve critical roles in development and operate as intermediaries that connect the genome to the rest of the world. Therefore, it is of interest to consider the evolution of epigenetic processes.

Network Coarsening Dynamics in a Plasmodial Slime Mould: Modelling and Experiments [PDF]
Acta Physica Polonica B, 2015 The giant unicellular slime mould Physarum polycephalum forms an extended network of stands (veins) that provide for an effective intracellular transportation system, which coarsens in time. The network coarsening was investigated numerically using an agent-based model and the results were compared to experimental observations.

Environmental Microbiology, Volume 23, Issue 11, Page 6924-6939, November 2021., 2021 Summary Nitric oxide (NO) is a signalling molecule in eukaryotic and prokaryotic organisms. NO levels transiently boost upon induction of conidiation in Aspergillus nidulans. Only one pathway for NO synthesis involving nitrate reductase has been reported in filamentous fungi so far, but this does not satisfy all the NO produced in fungal cells. Here we
