#Fungi disarm #BarkBeetle chemical shields by converting their plant-derived toxins phys.org/news/2025-12-fungus-b… pnas.org/doi/10.1073/pnas.2525…

"a bark beetle can co-opt a tree's defensive compounds to make defenses against its own enemies. However, since one of the enemies, the #fungus Beauveria bassiana, has developed the ability to detoxify these antimicrobial defenses, it can successfully infect the #BarkBeetles and thus actually help the tree in its battle against bark #beetles"

Fungus disarms bark beetle chemical shields by converting their plant-derived toxins

Spruce bark is rich in phenolic compounds that protect trees from pathogenic fungi. A research team at the Max Planck Institute for Chemical Ecology in Jena has investigated how these plant defenses function within the food web, particularly in spruc…

Genetic potential for aerobic respiration and denitrification in globally distributed respiratory endosymbionts - Nature Communications

In this study, the authors report and analyze four complete genomes of respiratory endosymbionts to show that they carry the potential to breathe both oxygen and nitrogen oxides providing energy to their hosts.

Genomic analyses of Symbiomonas scintillans show no evidence for endosymbiotic bacteria but does reveal the presence of giant viruses

Author summary Endosymbiotic bacteria are found in a wide variety of hosts across the tree of eukaryotes and have been proposed to be evolutionarily and ecologically significant, but in most cases, we know little to nothing about them.

How do bacterial endosymbionts work with so few genes?

The move from a free-living environment to a long-term residence inside a host eukaryotic cell has profound effects on bacterial function.

#Mutualism on the edge: Understanding the #Paramecium–#Chlorella symbiosis journals.plos.org/plosbiology/…

"Exploring the mechanisms that underpin #symbiosis requires an understanding of how these complex interactions are maintained in diverse model systems. The ciliate #protist, Paramecium bursaria, offers a valuable insight into how emergent endosymbiotic interactions have evolved."

Beyond pathogenesis: Detecting the full spectrum of ecological interactions in the virosphere

"Viral interactions with their hosts are complex and some non-pathogenic viruses could have potential benefits to society. However, viral research is seldom designed to identify viral mutualists, a gap that merits considering new experimental designs."

Beyond pathogenesis: Detecting the full spectrum of ecological interactions in the virosphere

Viral interactions with their hosts are complex and can be beneficial, yet the public perception of viruses is generally negative.

Tripartite interactions between filamentous Pf4 bacteriophage, Pseudomonas aeruginosa, and bacterivorous nematodes

"Collectively, our data support a model where suppression of quorum-regulated virulence factors by Pf4 allows P. aeruginosa to evade detection by innate host immune responses."

Tripartite interactions between filamentous Pf4 bacteriophage, Pseudomonas aeruginosa, and bacterivorous nematodes

Author summary Pseudomonas aeruginosa is an opportunistic bacterial pathogen that infects wounds, lungs, and medical hardware. P. aeruginosa strains are often themselves infected by a filamentous virus (phage) called Pf.

Bacterial lifestyle switch in response to algal metabolites

Opportunistic bacteria modulate their lifestyle from coexistence to pathogenicity by perceiving the physiological state of their algal host through sensing of algal secreted metabolites.
