Recovery of population genomes from surface ocean samples identified non-cyanobacterial diazotrophs that were widespread and abundant, including Proteobacteria and Planctomycetes, indicating their importance for nitrogen fixation in this environment.

The recovery of viral populations from peatland soils across a permafrost thaw gradient provides insights into soil viral diversity, their hosts and the potential impacts on carbon cycling in this environment.

The type VI secretion system of Serratia marcescens can deliver effector proteins that target fungi, including pathogenic Candida species, via disruption of nutrient uptake and metabolism or loss of plasma membrane potential.
