Widespread and intron-rich mirusviruses are predicted to reproduce in nuclei of unicellular eukaryotes Open
Mirusviruses infect unicellular eukaryotes and are related to tailed bacteriophages and herpesviruses. Here we expand the known diversity of mirusviruses by screening diverse metagenomic assemblies and characterizing 1,202 non-redundant en…

Mobilization of an ICEclc-Like Element as a Potential Mechanism for the Spread of IMP-13 Carbapenemase in Pseudomonas aeruginosa Open
Carbapenem-resistant Pseudomonas aeruginosa is a global public health concern. IMP-13 is a carbapenemase that was described for the first time in 2001 but is often underestimated due to poor hydrolysis of carbapenems and a lack of molecula…

Global Phylogeography of Marine <i>Synechococcus</i> in Coastal Areas Reveals Strong Community Shifts Open
Synechococcus is the second most abundant phytoplanktonic organism on Earth, and its wide genetic diversity allowed it to colonize all the oceans except for polar waters, with different clades colonizing distinct oceanic niches. In recent …

Global phylogeography of marine <i>Synechococcus</i> in coastal areas reveals strikingly different communities than in the open ocean Open
Marine Synechococcus comprise a numerically and ecologically prominent phytoplankton group, playing a major role in both carbon cycling and trophic networks in all oceanic regions except in the polar oceans. Despite their high abundance in…
