Comparative Genomics Insights Into the Evolutionary Disparities Between Nitroplast-Evolved Ecotype UCYN-A2 and Its Closest Relative UCYN-A1 [PDF]
Ecology and EvolutionUCYN‐A is a phenomenal diazotrophic cyanobacterium with significant ecological importance. UCYN‐A1 and UCYN‐A2 are the two most abundant ecotypes. Recently, the striking discovery of nitroplast, a novel N2‐fixing organelle in cultured B.

Primer Design for the Amplification of the Ammonium Transporter Genes From the Uncultured Haptophyte Algal Species Symbiotic With the Marine Nitrogen-Fixing Cyanobacterium UCYN-A1 [PDF]
Frontiers in Microbiology, 2023 The multiple symbiotic partnerships between closely related species of the haptophyte algae Braarudosphaera bigelowii and the nitrogen-fixing cyanobacteria Candidatus Atelocyanobacterium thalassa (UCYN-A) contribute importantly to the nitrogen and carbon

Open ocean and coastal strains of the N2-fixing cyanobacterium UCYN-A have distinct transcriptomes. [PDF]
PLoS ONE, 2023 Decades of research on marine N2 fixation focused on Trichodesmium, which are generally free-living cyanobacteria, but in recent years the endosymbiotic cyanobacterium Candidatus Atelocyanobacterium thalassa (UCYN-A) has received increasing attention ...

Critical Role of Light in the Growth and Activity of the Marine N2-Fixing UCYN-A Symbiosis
Frontiers in Microbiology, 2021 The unicellular N2-fixing cyanobacteria UCYN-A live in symbiosis with haptophytes in the Braarudosphaera bigelowii lineage. Maintaining N2-fixing symbioses between two unicellular partners requires tight coordination of multiple biological processes ...

Integrating Stochastic and Deterministic Process in the Biogeography of N2-Fixing Cyanobacterium Candidatus Atelocyanobacterium Thalassa [PDF]
Frontiers in Microbiology, 2021 UCYN-A is one of the most widespread and important marine diazotrophs. Its unusual distribution in both cold/warm and coastal/oceanic waters challenges current understanding about what drives the biogeography of diazotrophs.

Eddy-driven diazotroph distribution in the subtropical North Atlantic: horizontal variability prevails over particle sinking speed [PDF]
Communications BiologyMesoscale eddies influence the distribution of diazotrophic (nitrogen-fixing) cyanobacteria, impacting marine productivity and carbon export. Non-cyanobacterial diazotrophs (NCDs) are emerging as potential contributors to marine nitrogen fixation ...
