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...

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 ...

ProteomicsDynamic Acclimation to High Light in Arabidopsis thaliana Involves Widespread Reengineering of the Leaf Proteome
Typically, when fully developed leaves of Arabidopsis thaliana are exposed to an increase in light intensity, they are able to increase their photosynthetic capacity in a process known as dynamic acclimation. Fully developed leaves of Arabidopsis thaliana were exposed to a fourfold increase in light...

MetabolomicsResolving coral photoacclimation dynamics through coupled photophysiological and metabolomic profiling
Corals continuously adjust to short term variation in light availability on shallow reefs. Long-term light alterations can also occur due to natural and anthropogenic stressors, as well as management interventions such as coral transplantation. Although short term photophysiological responses are re...

ProteomicsAcclimation of the Arabidopsis thaliana thylakoid proteome to different light conditions
Arabidopsis thaliana Col-0 plants were grown under different light conditions. Chloroplasts were isolated and their proteins extracted. Proteins were analysed by LC-MS and a label free quantification strategy was used to compare the different proteome compositions responsible for the respective accl...

MetabolomicsMetabolic signatures of Arabidopsis thaliana abiotic stress responses elucidate patterns in stress priming, acclimation, and recovery

Temperature, water and light are 3 abiotic stress factors that have major influences on plant growth, development and reproduction. Plants can be primed by a prior mild stress to enhance their resistance to future stress. We used an untargeted metabolomics approach to examine Arabidopsis thal...

TranscriptomicsHaeusler LL_HL shift A. thaliana
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...

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...
