DOI: 10.1016/j.cub.2018.01.008
Abstract: Cyanobacteria were the ultimate ancestor of all plastids and, for much of Earth's history, the only source of biogenic oxygen and a major source of fixed carbon and nitrogen. One cyanobacterial clade, subsections IV+V, is… read more here.

DOI: 10.1093/plankt/fbx023
Abstract: Calothrix rhizosoleniae and Richelia intracellularis are widespread heterocystous nitrogen-fixing cyanobacteria in nitrate-limited tropical oceans. Most of them are symbiotic with diatom hosts (SYM), but some are free-living (FL). We investigated FL abundance in the South… read more here.
