A Bibliometric‐Based Review of Biochar for Salt‐Affected Soil Restoration: Mapping Research Trends and Future Directions

open access: yesLand Degradation &Development, Volume 37, Issue 13, Page 8963-8985, 15 August 2026.
ABSTRACT In recent years, biochar has been studied for its range of applications. Recognized by the IPCC as a key Carbon Dioxide Removal (CDR) strategy, it also stands out as an important tool for reclaiming degraded lands, including vast global areas affected by salinity, such as those in China, India, and Australia.

Extraction, Purification and Spectroscopic Characterization of Phycobiliproteins Extracted from some Nostoc Spp. [PDF]

open access: yesJournal of Agricultural Chemistry and Biotechnology, 2017
Phycocyanin and phycoerythrin are considered the major phycobiliprotein in many cyanobacteria as well as being a secondary phycobiliprotein in some red algae.

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 8, Page 1463-1480, August 2026.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Conserved symbiosis‐associated genes in the cycad Encephalartos natalensis suggest co‐option for cyanobacterial symbiosis

open access: yesNew Phytologist, Volume 251, Issue 4, Page 2168-2185, August 2026.
The heterocyst‐rich Encephalartos natalensis cyanobacterial zone in coralloid root suggests co‐option of conserved symbiosis‐associated genes. This figure was created in BioRender (BioRender.com/https://BioRender.com/n3qveqc). Summary Plant‐cyanobacterial symbioses have evolved independently at least four times across land plants, yet their underlying ...

Production of cyanobacterial toxins from two Nostoc species (Nostocales) and evaluation of their cytotoxicity in vitro [PDF]

open access: yesJournal of BioScience and Biotechnology, 2012
Cyanobacteria are among the oldest autotrophic organisms with cosmopolitan distribution and known as producers of secondary metabolites with toxic properties named "cyanotoxins".

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

open access: yesBMC 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 ...

Prospection of cyanobacteria producing bioactive substances and their application as potential phytostimulating agents

open access: yesBiotechnology Reports, 2020
This work clarifies some of the substances involved with the biostimulant effect shown by 28 cyanobacteria isolated from different aquatic environments. The production of salicylic acid, cytokinins, siderophores and phosphate solubilization were analyzed

Ecological niches and biogeography of nitrogen‐fixing plants in Europe

open access: yesPlant Biology, Volume 28, Issue 5, Page 1349-1360, August 2026.
Despite sharing N fixation as a common trait, European legume and actinorhizal plant lineages occupy strikingly divergent ecological niches shaped by their evolutionary histories and physiological adaptations. Advanced symbiont control allows IRLC legumes to expand into northern, mesic regions, while non‐IRLC legumes are more common in Mediterranean ...

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

open access: yesMicrobiology 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 ...

A Crack‐Based One‐Dimensional Microspheres Array Enables Thermal–Mechanical Decoupled Dual‐Functional Sensing

open access: yesAdvanced Science, Volume 13, Issue 41, 22 July 2026.
Inspired by Nostoc, a crack‐based one‐dimensional microspheres array (COMA) sensor is developed, which stabilizes crack geometry under isotropic expansion, enabling a predictable, monotonic thermal response from which true strain can be accurately extracted. The COMA sensor exhibits high sensitivity at ultralow deformation (gauge factor up to 89) and a
