Hernandez M, Jimenez-Lopez J, Cejudo F, Perez-Ruiz J
Plant Physiol
. 2024 Feb;
195(2):1521-1535.
PMID: 38386701
Fatty acid unsaturation levels affect chloroplast function and plant acclimation to environmental cues. However, the regulatory mechanism(s) controlling fatty acid unsaturation in thylakoid lipids is poorly understood. Here, we have...

Redox Biol
. 2023 Mar;
62:102645.
PMID: 36898225
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 mutant lacking...

Ojeda V, Jimenez-Lopez J, Romero-Campero F, Cejudo F, Perez-Ruiz J
Plant Physiol
. 2021 Oct;
187(1):88-102.
PMID: 34618130
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 Trx reductase (NTR)...

Cejudo F, Gonzalez M, Perez-Ruiz J
Plant Physiol
. 2021 Apr;
186(1):9-21.
PMID: 33793865
Regulation of enzyme activity based on thiol-disulfide exchange is a regulatory mechanism in which the protein disulfide reductase activity of thioredoxins (TRXs) plays a central role. Plant chloroplasts are equipped...

Duan L, Perez-Ruiz J, Cejudo F, Dinneny J
Plant Physiol
. 2021 Mar;
185(2):503-518.
PMID: 33721893
Photosynthesis in leaves generates fixed-carbon resources and essential metabolites that support sink tissues, such as roots. Two of these metabolites, sucrose and auxin, promote growth in root systems, but the...

Jurado-Flores A, Delgado-Requerey V, Galvez-Ramirez A, Puerto-Galan L, Perez-Ruiz J, Cejudo F
Antioxidants (Basel)
. 2020 Nov;
9(11).
PMID: 33142810
Thioredoxins (Trxs) are small, ubiquitous enzymes that catalyze disulphide-dithiol interchange in target enzymes. The large set of chloroplast Trxs, including , , and subtypes, use reducing equivalents fueled by photoreduced...

Front Plant Sci
. 2019 Apr;
10:380.
PMID: 31019520
Light is probably the most important environmental stimulus for plant development. As sessile organisms, plants have developed regulatory mechanisms that allow the rapid adaptation of their metabolism to changes in...

Ojeda V, Perez-Ruiz J, Cejudo F
Mol Plant
. 2018 Oct;
11(11):1377-1388.
PMID: 30292682
Most redox-regulated chloroplast enzymes are reduced during the day and oxidized during the night. While the reduction mechanism of light-dependent enzymes is well known, the mechanism mediating their oxidation in...

Perez-Ruiz J, Naranjo B, Ojeda V, Guinea M, Cejudo F
Proc Natl Acad Sci U S A
. 2017 Oct;
114(45):12069-12074.
PMID: 29078290
Thiol-dependent redox regulation allows the rapid adaptation of chloroplast function to unpredictable changes in light intensity. Traditionally, it has been considered that chloroplast redox regulation relies on photosynthetically reduced ferredoxin...

Ojeda V, Perez-Ruiz J, Gonzalez M, Najera V, Sahrawy M, Serrato A, et al.
Plant Physiol
. 2017 May;
174(3):1436-1448.
PMID: 28500266
Thiol-dependent redox regulation of enzyme activity plays a central role in the rapid acclimation of chloroplast metabolism to ever-fluctuating light availability. This regulatory mechanism relies on ferredoxin reduced by the...
