MetabolomicsThe Arabidopsis Concert of Metabolic Acclimation to High Light Stress

In plants, exposure to high light irradiation induces various stress responses, which entail complex metabolic rearrangements. To explore these dynamics, we conducted time-course experiments spanning 2 minutes to 72 hours with Arabidopsis thaliana under high and control light. Comparative metabol...

MetabolomicsInositol Pyrophosphates Mediate Chloroplast Lipid Remodeling and Nuclear Gene Repression during High-Light Acclimation in Chlamydomonas reinhardtii
Microalgae are photosynthetic organisms capable of autotrophic growth. Their applicability in multiple industrial fields has been largely studied, thanks to their ability to fixate CO2 into high added value organic products like fatty acids and carotenoids. However, our under-standing of the cellula...

TranscriptomicsGene expression from Arabidopsis under high light conditions
We have investigated the genomic response of Arabidopsis cell suspension culture under high light. Our main goal has been twofold: first, to establish whether chloroplasts in Arabidopsis cell suspension culture are functional and, as such, can act as sensors of adverse external stimuli leading to th...

TranscriptomicsAn Integrated Analysis of Molecular Acclimation to High Light in the Marine Diatom Phaeodactylum tricornutum
Photosynthetic diatoms are exposed to rapid and unpredictable changes in irradiance and spectral quality, and must be able to adapt their light harvesting systems to varying light conditions. Molecular mechanisms behind light acclimation in diatoms are largely unknown. We set out to investigate the ...

ProteomicsImpact of SliP4 deletion on the high-light acclimation in Synechocystis sp. PCC 6803
SliP4 is a 37 amino acids small protein that is strongly induced when the cyanobacterium Synechocystis is exposed to high-light conditions. Deletion mutants exhibit a light-sensitive phenotype due to impaired cyclic electron flow and state transitions. Here, we investigated the consequences of SliP4...

Wild-type (Col-0) and mutant plants (adg1-1, tpt-2, adg1-1/tpt-2) were grown for 28 days under low light conditions and were then transferred to HL. Leaf samples for transcriptional profiling were taken at time 0 (before transfer to high light) and 4 hours and 48 hours (2 days) after transfer to hig...

ProteomicsThe Role of Microbe-Enhanced Iron-Dependent Redox Metabolism in optimizing photosynthesis under high light stress in Arabidopsis
High light stress in subtropical and tropical regions strongly limits agricultural production due to photo-oxidative damage, decreased growth and yield. Here, we investigated whether beneficial microbes can protect plants under high light stress. We show that Enterobacter sp. SA187 (SA187) assists A...

ProteomicsProtein abundance changes in response to high light treatment
To characterize Arabidopsis proteomics and transcritomics changes in response to high light treatment. We quantify specific transcipts and protein abundance changes under both control and high light stress conditions. We aim to investigate the causality and interconnection of transcription and pr...

TranscriptomicsTranscription profiling of control and catalase-deficient Arabidopsis (Arabidopsis thaliana) plants
In plants, reactive oxygen species and, more particularly, hydrogen peroxide (H2O2) play a dual role as toxic by-products of normal cell metabolism and as regulatory molecules in stress perception and signal transduction. Peroxisomal catalases are an important sink for photorespiratory H2O2. Using A...
