Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

New Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

Transcript analysis of the extended hyp-operon in the cyanobacteria Nostoc sp. strain PCC 7120 and Nostoc punctiforme ATCC 29133

BMC Research Notes, 2011
Background Cyanobacteria harbor two [NiFe]-type hydrogenases consisting of a large and a small subunit, the Hup- and Hox-hydrogenase, respectively. Insertion of ligands and correct folding of nickel-iron hydrogenases require assistance of accessory ...

Corn response to biological products and a nitrification inhibitor

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Atmospheric nitrogen (N2) is converted into ammonia (NH3), a form that plants can use, through biological nitrogen (N) fixation by various microorganisms and bacterial genera. This study assessed the field performance of three biological N‐fixing products, or biostimulants (BS), including Gluconacetobacter diazotrophicus (BS1), Klebsiella ...

The structure characterized of Nostoc commune polysaccharide and antioxidant activity of Gansu Nostoc commune

, 2022
Abstract In this paper，Nostoc commune crude polysaccharide was extracted by hot water and Ultrasonic-assisted extraction, then purified by DEAE-cellulose52 cellulose column chromatography and Sephacryl G-100 gel column chromatography. Homogeneous polysaccharide HNCP3 extracted with hot water and UNCP4 extracted by ultrasound were obtained.

Influence of Temperature Variations on Growth of Nostoc (Cyanobacteria) HS-5 and HS-20 Isolated from Indonesian Hot Springs

Microbiology Indonesia, 2018
The research aims to know the effect of variation temperature to the growth of Nostoc HS (Hot Spring)-5 and HS-20. Strain of Nostoc HS-5 was isolated from Ciseeng hot spring which has habitat temperature range of 30-43 °C, and Nostoc HS-20 was isolated ...

Additions to the Fern Flora of Niue (Polynesia): First Records of Ophioglossum lusitanicum L., Ophioderma falcatum (C.Presl) O.Deg. and Psilotum complanatum Sw. and the Disjunct Occurrence of Ophioderma intermedium (Hook.) Nishida

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
During recent field survey for threatened and uncommon vascular plants in Niue, four ferns were collected and confirmed as additions to the indigenous flora. Ophioderma intermedium (Hook.) Nishida and O. falcatum (C.Presl) O.Deg. were collected from terrestrial habitats in primary tropical forest.

The Biosynthesis and Functions of Flavonoids: Recent Advances From Studies Across Land Plant Diversity

Journal of the Royal Society of New Zealand, Volume 56, Issue 3, June 2026.
Over the last decade there have been significant advances in genome sequencing and model species development for ferns, lycophytes, and the bryophyte lineages—mosses, liverworts, and hornworts. This has facilitated research on the biosynthesis and function of flavonoids in these non‐seed land‐plant lineages.

Bacterial Communities Associated With Spherical Nostoc Macrocolonies [PDF]

Frontiers in Microbiology, 2019
Species of the genus Nostoc (Cyanobacteria) can form large colonies of up to several centimeters in diameter that may represent a unique habitat for bacteria in freshwaters. Bacteria inside the colony are probably segregated from the surrounding water and largely dependent on the metabolism of this primary producer. However, the existence of a specific

Fog, Symbiosis, and Survival: The Ecological Architecture of the Grit Crust From the Atacama Desert Represents a Lichen Holobiome Rather Than a Soil Microbiome

Environmental Microbiology, Volume 28, Issue 6, June 2026.
Multi‐marker metabarcoding (16S rRNA, 18S rRNA, ITS2) of the fog‐dependent grit crust in the Atacama Desert reveals a community structured by lichen symbioses rather than typical soil‐derived microbial assemblages. The green algal photobiont Trebouxia dominates the eukaryotic community, accompanied by lichenized Caliciales and lichen‐associated ...
