Over‐Expression of a Phycocyanin‐Interferon Fusion and Differential Cleaving Efficiency in Cyanobacteria (Synechocystis sp. PCC 6803)

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Recombinant protein expression in heterologous biological systems is an expanding field in synthetic biology. Photosynthetic organisms have the potential to provide an efficient low‐cost platform for recombinant protein production because they require minimal growth nutrients and are less susceptible to zoonotic and other contaminants ...

The Application of Carbon Dots in Crops for Sustainable Agriculture

open access: yesChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...

Quantum-coherent dynamics in photosynthetic charge separation revealed by wavelet analysis

open access: yes, 2017
Experimental/theoretical evidence for sustained vibration-assisted electronic (vibronic) coherence in the Photosystem II Reaction Center (PSII RC) indicates that photosynthetic solar-energy conversion might be optimized through the interplay of ...

The photosystem I assembly apparatus consisting of Ycf3–Y3IP1 and Ycf4 modules

open access: yesNature Communications, 2018
In oxygenic photosynthesis, light energy is converted into redox energy by two photosystems (PSI and PSII). PSI forms one of the largest multiprotein complexes in thylakoid membranes consisting of a core complex, peripheral light-harvesting complexes ...

Detection of Radical Anions by Electrospray‐Ionization Mass Spectrometry

open access: yesHelvetica Chimica Acta, EarlyView.
The present study investigates the ability of electrospray‐ionization mass spectrometry to detect radical anions. For neutral analytes with high electron affinities, radical anions are formed by cathodic reduction and can be easily observed. In contrast, analytes with lower electron affinities require the addition of a reducing agent for the generation

Consequences of Decreased Light Harvesting Capability on Photosystem II Function in Synechocystis sp. PCC 6803

open access: yesLife, 2014
Cyanobacteria use large pigment-protein complexes called phycobilisomes to harvest light energy primarily for photosystem II (PSII). We used a series of mutants with partial to complete reduction of phycobilisomes to examine the effects of antenna ...

On the pathways feeding the H₂ production process in nutrient-replete, hypoxic conditions : commentary on the article 'Low oxygen levels contribute to improve photohydrogen production in mixotrophic non-stressed Chlamydomonas cultures', by Jurado-Oller et al., Biotechnology for Biofuels, published September 7, 2015; 8:149 [PDF]

open access: yes, 2017
Background: Under low O-2 concentration ( hypoxia) and low light, Chlamydomonas cells can produce H-2 gas in nutrient-replete conditions. This process is hindered by the presence of O-2, which inactivates the [FeFe]-hydrogenase enzyme responsible for H-2

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Sustained diurnal stimulation of cyclic electron flow in two tropical tree species Erythrophleum guineense and Khaya ivorensis

open access: yesFrontiers in Plant Science, 2016
The photosystem II (PSII) activity of C3 plants is usually inhibited at noon associated with high light but can be repaired fast in the afternoon. However, the diurnal variation of photosystem I (PSI) activity is unknown.
