Triple Threat: How Global Fungal Rice and Wheat Pathogens Utilize Comparable Pathogenicity Mechanisms to Drive Host Colonization.
Mol Plant Microbe Interact
January 2025
University of Florida, Microbiology and Cell Science, Gainesville, Florida, United States;
Plant pathogens pose significant threats to global cereal crop production, particularly for essential crops like rice and wheat, which are fundamental to global food security and provide nearly 40% of the global caloric intake. As the global population continues to rise, increasing agricultural production to meet food demands becomes even more critical. However, the production of these vital crops is constantly threatened by phytopathological diseases, especially those caused by fungal pathogens such as , the causative agent of rice blast disease, , responsible for head blight (FHB) in wheat, and , the source of Septoria tritici blotch (STB).

Objective: Studies in mouse models and human adults have shown that the intestinal microbiota composition can affect peripheral immune cells. We here examined whether the gut microbiota compositions affect B and T-cell subsets in children.
Methods: The intestinal microbiota was characterized from stool samples of 344 10-year-old children from the Generation R Study by performing 16S rRNA sequencing.
Specialized killing across the domains of life by the type VI secretion systems of Pseudomonas aeruginosa.

Type VI secretion systems (T6SSs) are widespread bacterial protein secretion machines that inject toxic effector proteins into nearby cells, thus facilitating both bacterial competition and virulence. Pseudomonas aeruginosa encodes three evolutionarily distinct T6SSs that each export a unique repertoire of effectors. Owing to its genetic tractability, P.

J Fungi (Basel)
December 2024
Leibniz Institute DSMZ, German Collection of Microorganisms and Cell Cultures, 38124 Braunschweig, Germany.
Helotiales, a diverse fungal order within Leotiomycetes (Ascomycota), comprises over 6000 species occupying varied ecological niches, from plant pathogens to saprobes and symbionts. Despite their importance, their genetic adaptations to temperature and environmental conditions are understudied. This study investigates temperature adaptations in infection genes and substrate degradation genes through a comparative genomics analysis of 129 Helotiales species, using the newly sequenced genomes of and .

Lichens are mutualistic associations consisting of a primary fungal host, and one to few primary phototrophic symbiont(s), usually a green alga and/or a cyanobacterium. They form complex thallus structures, which provide unique and stable habitats for many other microorganisms. Frequently isolated from lichens are the so-called black fungi, or black yeasts, which are mainly characterized by melanized cell walls and extremophilic lifestyles.
