2-Methylhopanoids are maximally produced in akinetes of Nostoc punctiforme: geobiological implications [PDF]

, 2009
2-Methylhopanes, molecular fossils of 2-methylbacteriohopanepolyol (2-MeBHP) lipids, have been proposed as biomarkers for cyanobacteria, and by extension, oxygenic photosynthesis.

Integrating phytoplankton phenology, traits, and model‐data fusion to advance bloom prediction

Limnology and Oceanography Letters, Volume 10, Issue 6, Page 815-834, December 2025.
Abstract While there is a diversity of approaches for modeling phytoplankton blooms, their accuracy in predicting the onset and manifestation of a bloom is still lagging behind what is needed to support effective management. We outline a framework that integrates trait theory and ecosystem modeling to improve bloom prediction.

Expanding the Role of FurA as Essential Global Regulator in Cyanobacteria.

PLoS ONE, 2016
In the nitrogen-fixing heterocyst-forming cyanobacterium Anabaena sp. PCC 7120, the ferric uptake regulator FurA plays a global regulatory role. Failures to eliminate wild-type copies of furA gene from the polyploid genome suggest essential functions. In

Taxonomic, phylogenetic and functional β‐diversity of stream algae is driven by the number of added nutrients and herbivory

Journal of Ecology, Volume 113, Issue 11, Page 3390-3405, November 2025.
Higher numbers of added nutrients (NAN) in treatment (T) relative to control (C) algal communities (1) and grazing (2) elevated taxonomic/phylogenetic nestedness (βNes) and functional gradient (βGra) components of β‐diversity. Herbivory favoured grazer‐resistant inferior competitors (2).

Vegetative cells may perform nitrogen fixation function under nitrogen deprivation in Anabaena sp. strain PCC 7120 based on genome-wide differential expression analysis.

PLoS ONE, 2021
Nitrogen assimilation is strictly regulated in cyanobacteria. In an inorganic nitrogen-deficient environment, some vegetative cells of the cyanobacterium Anabaena differentiate into heterocysts.

Gastric Signet Ring Cell Carcinoma: Tumor Microenvironment Reprogramming and Novel Therapeutic Targets With Emphasis on GRIN2D

Clinical and Translational Science, Volume 18, Issue 11, November 2025.
ABSTRACT Gastric Signet Ring Cell Carcinoma (GSRCC) is an increasingly recognized subtype of gastric cancer, particularly prevalent in South Asian populations and regions within India. This carcinoma is distinguished by its abundant cytoplasmic mucinous cells and aggressive clinical behavior, often affecting younger individuals and leading to a poor ...

Role of Two Cell Wall Amidases in Septal Junction and Nanopore Formation in the Multicellular Cyanobacterium Anabaena sp. PCC 7120

Frontiers in Cellular and Infection Microbiology, 2017
Filamentous cyanobacteria have developed a strategy to perform incompatible processes in one filament by differentiating specialized cell types, N2-fixing heterocysts and CO2-fixing, photosynthetic, vegetative cells. These bacteria can be considered true

Cyanobacterial Bloom Development, Nitrogen Fixation and Community Change: Insights on Rapid Change From a Shallow Lake

Freshwater Biology, Volume 70, Issue 11, November 2025.
ABSTRACT Nutrient‐rich lakes are highly susceptible to cyanobacterial blooms. During blooms, the consumption of dissolved inorganic nutrients can be rapid, but nitrogen (N) limitation can be mitigated through N2 fixation by cyanobacterial diazotrophs.

A Minority of Desert Cyanobacteria and Algae Is Responsible for the Bulk of CO2 Fixation

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Cyanobacteria and algae are the major photosynthetic organisms in deserts because they survive desiccation, high solar radiation and extreme temperature fluctuations better than other plants. Under favourable conditions, desert cyanobacteria and algae evidently photosynthesise.

The smallest known genomes of multicellular and toxic cyanobacteria: comparison, minimal gene sets for linked traits and the evolutionary implications. [PDF]

PLoS ONE, 2010
Cyanobacterial morphology is diverse, ranging from unicellular spheres or rods to multicellular structures such as colonies and filaments. Multicellular species represent an evolutionary strategy to differentiate and compartmentalize certain metabolic ...
