Plant responses to fungal volatiles involve global posttranslational thiol redox proteome changes that affect photosynthesis
(Wiley-Blackwell, 2019)
Microorganisms produce volatile compounds (VCs) that promote plant growth and photosynthesis through complex mechanisms involving cytokinin (CK) and abscisic acid (ABA). We hypothesized that plants' responses to microbial ...

A chloroplast redox relay adapts plastid metabolism to light and affects cytosolic protein quality control
(American Society of Plant Biologists, 2021)
In chloroplasts, thiol-dependent redox regulation is linked to light since the disulfide reductase activity of thioredoxins (Trxs) relies on photo-reduced ferredoxin (Fdx). Furthermore, chloroplasts harbor an NADPH-dependent ...

Biochemical characterization of the amylase activity from the new haloarchaeal strain haloarcula sp. Hs isolated in the odiel marshlands
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Alpha‐amylases are a large family of α,1‐4‐endo‐glycosyl hydrolases distributed in all kingdoms of life. The need for poly‐extremotolerant amylases encouraged their search in extreme environments, where archaea become ideal ...

Communication between L–galactono–1,4–lactone dehydrogenase and cytochrome c
(Wiley: FEBS Journal, 2013-02-25)
l‐galactono‐1,4‐lactone dehydrogenase (GALDH) catalyzes the terminal step of vitamin C biosynthesis in plant mitochondria. Here we investigated the communication between Arabidopsis thaliana GALDH and its natural electron ...

Phosphorylation of CONSTANS and its COP1-dependent degradation during photoperiodic flowering of Arabidopsis
(Blackwell Publishing, 2015)
Seasonal flowering involves responses to changes in day length. In Arabidopsis thaliana, the CONSTANS (CO) transcription factor promotes flowering in the long days of spring and summer. Late flowering in short days is due ...

Photorespiration: regulation and new insights on the potential role of persulfidation
(Oxford University Press, 2023-07-24)
Photorespiration has been considered a 'futile' cycle in C3 plants, necessary to detoxify and recycle the metabolites generated by the oxygenating activity of Rubisco. However, several reports indicate that this metabolic ...

Monitoring autophagy in the model green microalga chlamydomonas reinhardtii
(MDPI, 2017-10-22)
Autophagy is an intracellular catabolic system that delivers cytoplasmic constituents and organelles in the vacuole. This degradative process is mediated by a group of proteins coded by autophagy-related (ATG) genes that ...

A loop unique to ferredoxin-dependent glutamate synthases is not absolutely essential for ferredoxin-dependent catalytic activity
(Springer, 2015)
It had been proposed that a loop, typically containing 26 or 27 amino acids, which is only present in monomeric, ferredoxin-dependent, “plant-type” glutamate synthases and is absent from the catalytic α-subunits of both ...

Inorganic Pyrophosphatases: Study of Interest
(Scientific Research Publishing, 2017)
Inorganic pyrophosphatases are enzymes that catalyze the hydrolysis of inorganic pyrophosphate to orthophosphate. These enzymes are divided into two groups: the soluble pyrophosphatases and the membrane pyrophosphatases. ...

The dynamic complex of cytochrome c6 and cytochrome f studied with paramagnetic NMR spectroscopy
(Elsevier B.V., 2014)
The rapid transfer of electrons in the photosynthetic redox chain is achieved by the formation of short-lived complexes of cytochrome b6f with the electron transfer proteins plastocyanin and cytochrome c6. A balance must ...
