#microsky #phagesky #phage At last! Great to see this one out: journals.plos.org/plospathogen... Here, we discovered a nested phage-bacteria network despite their high genetic and ecological diversity. Kudos to everyone involved, especially @chloe-feltin.bsky.social ! @phimresearch.bsky.social

Ecological ubiquity and phylogeny drive nestedness in phages–bacteria networks and shape the bacterial defensome

Author summary Viruses that infect bacteria, known as phages, are part of microbial communities and influence the abundance, diversity, and traits of their hosts. In an agriculture-related context, th...

Want to know more about the bacterial leaf streak pathogen #Xanthomonas oryzae pv. oryzicola and the role of rice seed trade in the pathogen's spread in West Africa? Using genome sequencing and satellite markers, we describe its population structure and molecular epidemiology doi.org/10.1128/aem....

Large- and small-scale population structure of Xanthomonas oryzae pv. oryzicola, a bacterial pathogen of rice | Applied and Environmental Microbiology

West Africa has faced a rapid expansion of rice cultivation with importation of rice varieties mostly from Asia, and rice now constitutes 37% of the cereal consumed in the region. The bacterial pathog...

Thrilled to share that the first chapter of my PhD thesis has just been published! Our study shows that interactions between wheat varieties can modulate both the mean and variance of susceptibility to Septoria tritici blotch. 🌱↔️🌱 📖 Read the full article here: doi.org/10.1093/jxb/...

General mechanisms for a top–down origin of the predator–prey power law

The ratio of predator-to-prey biomass density is not constant along ecological gradients: denser ecosystems tend to have fewer predators per prey, following a scaling relation known as the ‘predator–....

After many years in the making, here is our host range #phage paper with #ecology, #evolution and #biocontrol perspectives published in Molecular Ecology! @phimresearch.bsky.social‬ @inrae-pv.bsky.social‬ #PVBMT #JulianGarneau onlinelibrary.wiley.com/doi/10.1111/... These are our key findings:

A Phylogenetic Host‐Range Index Reveals Ecological Constraints in Phage Specialisation and Virulence

Phages are typically known for having a limited host range, targeting particular strains within a bacterial species, but accurately measuring their specificity remains challenging. Factors like the g...
