Saint-Sorny M, Dimitriades A, Delrue F, Johnson X
Physiol Plant
. 2024 Sep;
176(5):e14539.
PMID: 39329246
Nutrient deprivation induces reserve accumulation in unicellular algae. An absence of nitrogen in the growth media results in the reorganization of the photosynthetic apparatus and triggers an increase in starch...

Commun Biol
. 2023 May;
6(1):529.
PMID: 37193883
Using a mutant screen, we identified trehalose 6-phosphate phosphatase 1 (TSPP1) as a functional enzyme dephosphorylating trehalose 6-phosphate (Tre6P) to trehalose in Chlamydomonas reinhardtii. The tspp1 knock-out results in reprogramming...

Hirt H, Al-Babili S, Almeida-Trapp M, Martin A, Aranda M, Bartels D, et al.
Trends Plant Sci
. 2023 Feb;
28(5):537-543.
PMID: 36740490
Greenhouse gas (GHG) emissions have created a global climate crisis which requires immediate interventions to mitigate the negative effects on all aspects of life on this planet. As current agriculture...

Wang F, Dischinger K, Westrich L, Meindl I, Egidi F, Trosch R, et al.
Plant Physiol
. 2023 Jan;
191(3):1612-1633.
PMID: 36649171
In land plants and cyanobacteria, co-translational association of chlorophyll (Chl) to the nascent D1 polypeptide, a reaction center protein of photosystem II (PSII), requires a Chl binding complex consisting of...

Saint-Sorny M, Brzezowski P, Arrivault S, Alric J, Johnson X
Front Plant Sci
. 2022 May;
13:876439.
PMID: 35574084
A RuBisCO-less mutant, Δ, was used to study carbohydrate metabolism without fixation of atmospheric carbon. The regulatory mechanism(s) that control linear electron flow, known as "photosynthetic control," are amplified in...

Plant Physiol
. 2020 Apr;
183(4):1749-1764.
PMID: 32327546
Protein phosphorylation plays important roles in short-term regulation of photosynthetic electron transfer, and during state transitions, the kinase STATE TRANSITION7 (STT7) of phosphorylates components of light-harvesting antenna complex II (LHCII)....

PMID: 31069268
In the last common enzymatic step of tetrapyrrole biosynthesis, prior to the branching point leading to the biosynthesis of heme and chlorophyll, protoporphyrinogen IX (Protogen) is oxidised to protoporphyrin IX...

. 2018 Apr;
177(2):465-475.
PMID: 29703866
Site-directed mutagenesis of chloroplast genes was developed three decades ago and has greatly advanced the field of photosynthesis research. Here, we describe a new approach for generating random chloroplast gene...

94(6):1023-1037.
PMID: 29602195
The GreenCut encompasses a suite of nucleus-encoded proteins with orthologs among green lineage organisms (plants, green algae), but that are absent or poorly conserved in non-photosynthetic/heterotrophic organisms. In Chlamydomonas reinhardtii,...

Plant J
. 2018 Mar;
94(5):822-835.
PMID: 29575329
Photosynthetic organisms have evolved numerous photoprotective mechanisms and alternative electron sinks/pathways to fine-tune the photosynthetic apparatus under dynamic environmental conditions, such as varying carbon supply or fluctuations in light intensity....
