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...

Plant–plant interactions in wheat mixtures modulate mean and variance of susceptibility to Septoria tritici blotch Wheat varietal mixtures modulate the mean and variance of Septoria tritici blotch disease symptoms through specific plant–plant interactions, with mixtures

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. 🌱↔️🌱
