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.

Molecular Diffusion through Cyanobacterial Septal Junctions

mBio, 2017
Heterocyst-forming cyanobacteria grow as filaments in which intercellular molecular exchange takes place. During the differentiation of N2-fixing heterocysts, regulators are transferred between cells.

HetR-dependent and -independent expression of heterocyst-related genes in an Anabaena strain overproducing the NtcA transcription factor [PDF]

, 2005
Heterocyst development in the cyanobacterium Anabaena sp. strain PCC 7120 depends on both the global nitrogen control transcription factor NtcA and the cell differentiation regulatory protein HetR, with expression of ntcA and hetR being dependent on each

Mathematical study of pattern formation accompanied by heterocyst differentiation in multicellular cyanobacterium [PDF]

Journal of Theoretical Biology, 2015
The filamentous cyanobacterium, Anabaena sp. PCC 7120, is one of the simplest models of a multicellular system showing cellular differentiation. In nitrogen-deprived culture, undifferentiated vegetative cells differentiate into heterocysts at ~10-cell intervals along the cellular filament.

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).

Rapid Transcriptional Reprogramming Triggered by Alteration of the Carbon/Nitrogen Balance Has an Impact on Energy Metabolism in Nostoc sp. PCC 7120

Life, 2020
Nostoc (Anabaena) sp. PCC 7120 is a filamentous cyanobacterial species that fixes N2 to nitrogenous compounds using specialised heterocyst cells.

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 ...

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.

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

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.
