The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome
Biological Reviews, EarlyView.ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Social organization and habitat use shape the gut microbiome of a marine fish
Journal of Animal Ecology, EarlyView.This study provides the first evidence linking habitat use—and to a lesser extent social organization—to gut microbiome composition in a wild marine fish. The results indicate that local habitat conditions are the primary driver of microbial variation, while social effects are detectable but weak.

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina
Insect Conservation and Diversity, EarlyView.Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Roles of PknB and CslA in Cell Wall Morphogenesis of Streptomyces
Molecular Microbiology, EarlyView.Streptomyces grow by extending hyphal tips, a process regulated by polarisome complexes anchored by DivIVA. Using a genetic screen based on toxic DivIVA overproduction, we identified the kinase PknB as a key regulator of cell envelope construction.
