Back to the future: Transplanting the chloroplast TrxF–FBPase–SBPase redox system to cyanobacteria
(Frontiers Media S.A., 2022)
Fructose-1,6-bisphosphatase (FBPase) and sedoheptulose-1,7-bisphosphatase (SBPase) are two essential activities in the Calvin–Benson–Bassham cycle that catalyze two irreversible reactions and are key for proper regulation ...

Stress-related biomolecular condensates in plants
(American Society of Plant Biologists, 2023-09)
Biomolecular condensates are membraneless organelle-like structures that can concentrate molecules and often form through liquid-liquid phase separation. Biomolecular condensate assembly is tightly regulated by developmental ...

Sulfide promotes tolerance to drought through protein persulfidation in Arabidopsis
(Oxford University Press, 2023-08-17)
Hydrogen sulfide (H2S) is a signaling molecule that regulates essential plant processes. In this study, the role of H2S during drought was analysed, focusing on the underlying mechanism. Pretreatments with H2S before ...

The Role of SepF in Cell Division and Diazotrophic Growth in the Multicellular Cyanobacterium Anabaena sp. Strain PCC 7120
(Elsevier, 2023)
The cyanobacterium Anabaena forms filaments of cells that grow by intercalary cell division producing adjoined daughter cells connected by septal junction protein complexes that provide filament cohesion and intercellular ...

Arabidopsis plants deficient in plastidial glyceraldehyde-3-phosphate dehydrogenase show alterations in abscisic acid (ABA) signal transduction: interaction between ABA and primary metabolism
(Oxford University Press, 2011)
Abscisic acid (ABA) controls plant development and regulates plant responses to environmental stresses. A role for ABA in sugar regulation of plant development has also been well documented although the molecular mechanisms ...

Analysis of Salmonella lineage-specific traits upon cell sorting
(Frontiers Media SA, 2023-03-29)
Microbial cell individuality is receiving increasing interest in the scientific community. Individual cells within clonal populations exhibit noticeable phenotypic heterogeneity. The advent of fluorescent protein technology ...

Phosphorylation disrupts long-distance electron transport in cytochrome c
(Springer Nature, 2022)
t has been recently shown that electron transfer between mitochondrial cytochrome c and the cytochrome c1 subunit of the cytochrome bc1 can proceed at long-distance through the aqueous solution. Cytochrome c is thought to ...

Chloroplast Lipids Metabolism and Function. A Redox Perspective
(Frontiers Media, 2021)
Plant productivity is determined by the conversion of solar energy into biomass through oxygenic photosynthesis, a process performed by protein-cofactor complexes including photosystems (PS) II and I, and ATP synthase. ...

Plastid 2-Cys peroxiredoxins are essential for embryogenesis in Arabidopsis
(Elsevier, 2023)
The redox couple formed by NADPH-dependent thioredoxin reductase C (NTRC) and 2-Cys peroxiredoxins (Prxs) allows fine-tuning chloroplast performance in response to light intensity changes. Accordingly, the Arabidopsis 2cpab ...

Chitosan is involved in elicitation of vestitol production in Lotus japonicus
(Springer Nature, 2023-05-16)
Leaves of Lotus japonicus infected by powdery mildew accumulate isoflavonoids, especially vestitol and sativan as protective compounds, whereas their flavonol-glycosides or phenylpropanoic acids content were rather decreased. ...
