In situ analysis of natural Crocosphaera populations revealed diel cycling of transcript abundances for a range of metabolic pathways, indicating that these cyanobacteria are dominant nitrogen fixers and contributors to primary productivity.
We anticipate that conventional management approaches will be insufficient to protect coral reefs, even if global warming is limited to 1.5 °C. Emerging technologies are needed to stem the decline of these natural assets.
A recent study identified a host-derived ammonium transporter in the genome of an algal virus that increases the rate of nitrogen uptake by infected cells and changes how the host accesses diverse nitrogen sources during infection.
