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...

MetabolomicsSystems acclimation to osmotic stress in zygnematophyte cells

Zygnematophytes are the closest algal relatives of land plants. They hold key information to infer how the earliest land plants overcame the barrage of terrestrial stressors, prime of which is osmotic stress. Here, we applied two osmotic stressors on a unicellular and a multicellular representati...

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...

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...

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...

ProteomicsArabidopsis thaliana acclimation to fluctuating light
Plants are subjected to perpetual fluctuations of light intensity and spectral composition in their natural growth environment, particularly due to movement of clouds and upper canopy leaves. Sudden exposure to intense light is accompanied by absorption of excess light energy, which results in an ov...

ProteomicsFast light changes promote distinct responses of plastid protein acetylation marks
Protein acetylation is a key recurring co- and posttranslational modification. How different types of acetylation respond to the same environmental stress is unknown. A member of the newly discovered family of plastid acetyltransferases (GNAT2), which is featuring both lysine- and N-terminal acetyl...
