New work out! A multilayered network reveals the centrality of Nucleocytoviricota in wastewater treatment plant communities
In a collaboration with Anouk Willemsen and led by Dominik (VEE lab), we reconstructed high-quality genomes from diverse Waste-water treatment plants (61 novel nucleocytoviruses, 15 virophages and 14 polinton-like viruses). We aimed to study interactions… read more

New work out! Co-evolution and synchronised evolutionary rates in aphid dual endosymbiont systems
Aphids typically rely on the obligate symbiont Buchnera, but several lineages have acquired additional co-obligate symbionts, most commonly Serratia symbiotica. Through phylogenetic analyses, we found that a clade of Cinara aphids shows strict co-speciation between… read more
