Comparative metagenomic analysis reveals mechanisms for stress response in hypoliths from extreme hyperarid deserts [PDF]
, 2016 Understanding microbial adaptation to environmental stressors is crucial for interpreting broader ecological patterns. In the most extreme hot and cold deserts, cryptic niche communities are thought to play key roles in ecosystem processes and represent ...

Synergistic effects of nutrients and light favor Nostocales over non-heterocystous cyanobacteria
Hydrobiologia, 2017 Blooms of Nostocales (Cyanobacteria) are thought to be invading subtropical and temperate water bodies. According to nutrient stoichiometry and physiological differences between cyanobacterial groups, the replacement of non-heterocystous species by Nostocales is favored when dissolved inorganic nitrogen decreases.

A potential cyanobacterial ancestor of Viridiplantae chloroplasts [PDF]
, 2011 The theory envisaging the origin of plastids from endosymbiotic cyanobacteria is well-established but it is difficult to explain the evolution (spread) of plastids in phylogenetically diverse plant groups.
