Comparative proteomics of thylakoids from Arabidopsis grown in laboratory and field conditions

Plant Direct, 2021
Compared to controlled laboratory conditions, plant growth in the field is rarely optimal since it is frequently challenged by large fluctuations in light and temperature which lower the efficiency of photosynthesis and lead to photo‐oxidative stress ...

Integrated Multi‐Omic Analyses Uncover a Regulatory Link Between Photosynthesis and Drought Tolerance in Field‐Grown Sorghum

Plant, Cell &Environment, Volume 49, Issue 9, Page 6748-6764, September 2026.
ABSTRACT Global warming and increasing water scarcity pose major challenges to agriculture, emphasising the need to translate stress‐biology insights into the development of drought‐resilient cultivars. In this study, we evaluated a panel of six diverse sorghum (Sorghum bicolour) accessions grown under field‐imposed drought conditions in central ...

Enhanced Production of D-Lactate in Cyanobacteria by Re-Routing Photosynthetic Cyclic and Pseudo-Cyclic Electron Flow

Frontiers in Plant Science, 2020
Cyanobacteria are promising chassis strains for the photosynthetic production of platform and specialty chemicals from carbon dioxide. Their efficient light harvesting and metabolic flexibility abilities have allowed a wide range of biomolecules, such as

Essential mitochondrial activity in Physcomitrium patens relies on complementary cytochrome and alternative oxidase pathways

The Plant Journal, Volume 127, Issue 5, September 2026.
SUMMARY Mitochondrial respiration catalyses the transfer of electrons from NADH to oxygen through the activity of five multiprotein complexes. In plants, mitochondria also possess additional alternative electron transport pathways, including the alternative oxidase (AOX) pathway, which transfers electrons from ubiquinol to O2, bypassing the cytochrome ...

Chloroplast ATP Synthase Modulation of the Thylakoid Proton Motive Force: Implications for Photosystem I and Photosystem II Photoprotection

Frontiers in Plant Science, 2017
In wild type plants, decreasing CO2 lowers the activity of the chloroplast ATP synthase, slowing proton efflux from the thylakoid lumen resulting in buildup of thylakoid proton motive force (pmf).

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.

Structural proteomics reveals the functional docking interface of ferredoxin‐NADP+ reductase on photosystem I in the red alga Cyanidioschyzon merolae

The Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY Efficient photosynthetic electron transfer relies on transient interactions between photosystem I (PSI) and soluble electron carriers. However, structural information describing these transient interactions are limited in red algae. Here, we applied chemical cross‐linking mass spectrometry (XL‐MS) to isolated thylakoid membranes of the red alga

Enhanced Reduction of Ferredoxin in PGR5-Deficient Mutant of Arabidopsis thaliana Stimulated Ferredoxin-Dependent Cyclic Electron Flow around Photosystem I. [PDF]

Int J Mol Sci
The molecular entity responsible for catalyzing ferredoxin (Fd)-dependent cyclic electron flow around photosystem I (Fd-CEF) remains unidentified. To reveal the in vivo molecular mechanism of Fd-CEF, evaluating ferredoxin reduction–oxidation ...

Complete Chloroplast Genome of the Eria Sensu Lato Complex (Orchidaceae): Comparative Analysis and Phylogenetic Relationship

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We sequenced and assembled 18 complete chloroplast genomes representing the Eria sensu lato complex. Our comparative analyses unveiled stepwise NDH complex degradation, lineage‐specific positive selection on ycf1, and climate‐driven rapid radiation during the Late Miocene.
