Signaling Pathways Regulating Dimorphism in Medically Relevant Fungal Species

Pathogens
Pathogenic fungi that exhibit the ability to alternate between hyphal and yeast morphology in response to environmental stimuli are considered dimorphic. Under saprobic conditions, some fungi exist as filamentous hyphae, producing conidia.

NADPH Dehydrogenase Gene Regulates Energy Distribution and Fatty Acid Metabolism During Fruiting Body Formation in the Filamentous Fungus Podospora anserina

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
NADPH dehydrogenase gene deletion significantly triggered NADPH/NADP+ increase in mutant strains. NADPH gene deletion promoted Fatty acid biosynthesis and repressed β‐oxidation. NADPH gene deletion decreased oxidative phosphorylation and increased substrate‐level phosphorylation. Mutants exhibited hypersensitivity to oxidative stress, but promoted more

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, Volume 250, Issue 5, Page 2778-2813, June 2026.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Genome analysis reveals evolutionary mechanisms of adaptation in systemic dimorphic fungi

, 2017
Dimorphic fungal pathogens cause a significant human disease burden and unlike most fungal pathogens affect immunocompetent hosts. To examine the origin of virulence of these fungal pathogens, we compared genomes of classic systemic, opportunistic, and ...

Ammonium Signalling in Dimorphic Fungi [PDF]

, 2020
Ph. D. ThesisAmmonium is a preferred source of nitrogen utilised by fungi. In some fungi ammonium availability is sensed by ammonium transporters belonging to the Amt/Mep/Rh superfamily. During ammonium limiting conditions these transporters trigger a

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

New Phytologist, Volume 250, Issue 6, Page 3613-3630, June 2026.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).

The Ecology of Non-Candida Yeasts and Dimorphic Fungi in Cetaceans: From Pathogenicity to Environmental and Global Health Implications Journal of Fungi

Cetaceans, which are integral to marine ecosystems, face escalating anthropogenic threats, including climate change and pollution, positioning them as critical sentinel species for ocean and human health. This review explores the neglected realm of non-

Nonclassical MHC‐I Molecules: Emerging Therapeutic Targets in Next‐Generation Immunotherapy

MedComm, Volume 7, Issue 5, May 2026.
Immunotherapies dependent on classical MHC‐I molecules face significant challenges, including extreme polymorphism and frequent downregulation in pathological conditions. This review discusses how nonclassical MHC‐I molecules (HLA‐E, HLA‐F, HLA‐G, CD1, MR1) may potentially circumvent these limitations through restricted genetic diversity, stable ...
