Rapid CO2 effects on protein‐related metabolism during photosynthetic gas exchange

The Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY It is common practice to vary atmospheric CO2 mole fraction (Ca) during gas exchange experiments to manipulate photorespiration and explore photosynthetic properties such as maximum carboxylation velocity. In doing so, it is assumed that changing Ca essentially alters the carboxylation‐to‐oxygenation ratio, with negligible effects on other ...

Overexpression of the protein disulfide isomerase AtCYO1 in chloroplasts slows dark-induced senescence in Arabidopsis

BMC Plant Biology, 2018
Background Chlorophyll breakdown is the most obvious sign of leaf senescence. The chlorophyll catabolism pathway and the associated proteins/genes have been identified in considerable detail by genetic approaches combined with stay-green phenotyping ...

The Elusive Fraction of Marine Plankton Diversity: Size, Abundance and Taxonomic Composition of 0.2 μm‐Filterable Prokaryotes Across Three Contrasting Coastal Environments

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The existence of prokaryotes escaping filtration through 0.2‐μm filters has been known for decades. Such ‘filterable’ prokaryotes (hereafter ‘FP’) might include true ultra‐small groups (i.e., ultramicrobacteria), but also cells that miniaturize temporally as a physiological strategy to persist under unfavourable conditions, representing a ...

Effect of Light on Chemical Modification of Chloroplast Ferredoxin-NADP Reductase [PDF]

Plant Physiology, 1980
Chemical modification of spinach chloroplasts by phenylglyoxal and dansyl chloride resulted in inhibition of NADP photoreduction. The rate of inactivation was higher with both reagents when modification was carried out in the light with methylviologen or phenazine methosulfate present. Uncouplers prevent the effect of light.

Deciphering photosynthetic protein networks: a crosslinking‐MS strategy for studying functional thylakoid membranes

The Plant Journal, Volume 126, Issue 5, June 2026.
SUMMARY Photosynthesis, which sustains life on Earth, depends on organized and yet adaptable protein assemblies embedded in specialized membranes known as thylakoids. Understanding how these complexes interact and reorganize within functional photosynthetic membranes is essential to reveal the molecular basis of energy conversion in cells.

Functional and structural insights into cyanobacterial CO2 concentrating mechanisms: from compartmentalization to regulation

The Plant Journal, Volume 126, Issue 5, June 2026.
Significance Statement Life on Earth depends on photosynthetic CO2 fixation via the Calvin–Benson–Bassham cycle to form organic carbon. This process evolved first in cyanobacteria and was later conveyed to eukaryotes, giving rise to plastids in algae and plants. To cope with low atmospheric CO2 concentrations that developed over the course of evolution,

Integrated Single‐Cell and Spatial Transcriptomics Reveal Cell‐Type‐Specific Immune Regulatory Networks in Maize Responding to Southern Corn Rust

Advanced Science, Volume 13, Issue 27, 13 May 2026.
By integrating single‐nuclei and spatial transcriptomics, this study presents a stereoscopic landscape of maize leaf to Puccinia polysora infection. Epidermal and mesophyll cells initiate primary defenses via RLPs/RLKs and jasmonic acid signaling. Cell‐cell communication analyses further reveal the underlying the dynamics of the underlying immune ...

Thiol post‐translational modifications modulate allosteric regulation of the OpcA–G6PDH complex through conformational gate control

Protein Science, Volume 35, Issue 5, May 2026.
Abstract In cyanobacteria, the redox‐sensitive protein OpcA acts as a metabolic switch for G6PDH, enabling rapid adjustment of reducing power generation from glycogen catabolism and thereby precisely regulating carbon flux between anabolic and catabolic pathways.

Emerging Technologies for Biobutanol Production via Syngas Fermentation

GCB Bioenergy, Volume 18, Issue 5, May 2026.
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...
