Evaluating the Combined Effects of Elevated [CO2] and Accelerated NPQ Relaxation on Yield, Physiology and Transcription in Soybean

Plant, Cell &Environment, Volume 49, Issue 8, Page 6169-6187, August 2026.
ABSTRACT Improving photosynthesis is proposed as a means of enhancing crop productivity. To assess whether simultaneous increases in light use‐efficiency and carbon assimilation are additive, we investigated the impact of elevated CO2 on the performance of a transgenic soybean line engineered for faster relaxation of photoprotection by overexpression ...

Cold stress impairs CurT accumulation and thylakoid architecture in Synechocystis sp. PCC 6803

Frontiers in Plant Science
Low-temperature stress affects the thylakoid membrane system in both cyanobacteria and chloroplasts. In this study, a previously unrecognized link between cold-stress acclimation and the thylakoid-shaping CurT abundance in Synechocystis sp.

Size of chloroplasts in Arabidopsis mesophyll cells affects jasmonate biosynthesis

Plant Biology, Volume 28, Issue 5, Page 1330-1342, August 2026.
The relationship between chloroplast structure and hormone biosynthesis capacity is poorly understood. This study shows that mutants harbouring giant chloroplasts produce more jasmonic acid upon mechanical stress than wild‐type plants, suggesting that organellar architecture is a previously unrecognized factor associated with plant hormone biosynthesis

On the relationship between Photosystem II thermotolerance and irreversible heat damage in leaves of Rhizophora mangle

Plant Biology, Volume 28, Issue 5, Page 1596-1601, August 2026.
Temperature‐F0 fluorescence curves of Rhizophora mangle leaves demonstrate that Tcrit, the temperature at which F0 begins to rise, is unrelated to tissue necrosis; irreversible leaf damage starts to occur at significantly higher temperatures where fluorescence emission is maximal. Abstract Global temperatures are on the rise and may, together with more

CurT/CURT1 proteins are involved in cell and chloroplast division coordination of cyanobacteria and green algae

Nature Communications
Plant proteins of the CURVATURE THYLAKOID 1 (CURT1) family and their prokaryotic CurT homologues are key determinants of the three-dimensional structure of the thylakoid membrane systems in chloroplasts and cyanobacteria.

Phycobilisomes: modular light‐harvesting systems of cyanobacteria and red algae

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Phycobilisomes (PBSs) are supramolecular pigment–protein complexes that function as the principal light‐harvesting antennae in cyanobacteria, red algae (Rhodophyta), and glaucophytes, and to a lesser extent in cryptophytes. Because the intrinsic chlorophyll‐based antennae of the photosystems absorb poorly in the green region of the spectrum ...

Spectroscopic Investigation of the In Vivo Light‐Dependent Photodynamics of the Marine Diatom Phaeodactylum tricornutum

ChemPhysChem, Volume 27, Issue 13, 14 July 2026.
µm fourier transform infrared (FTIR) image, 442 nm Raman of the Si–O of the silica‐based frustule at 472 cm−1, and UV–vis of Phaeodactylum tricornutum cells. Marine diatoms are responsible for fixing CO2 into organic carbon and contribute to the regulation of global climate.
