MetabolomicsApoplastic metabolomics reveals sugars as mesophyll messengers regulating guard cell ion transport under red light
Here we sought to identify mesophyll messenger(s) that promote stomatal opening under red light. We first established a method to isolate leaf apoplastic fluids from Arabidopsis thaliana and Vicia faba and ascertained that the apoplastic fluid enhances red light-induced stomatal opening. We then app...

MetabolomicsMetabolomics of red-light-induced stomatal opening in Arabidopsis thaliana: Coupling with abscisic acid and jasmonic acid metabolism
Environmental stimuli-triggered stomatal movement is a key physiological process that regulates CO2 uptake and water loss in plants. Stomata are defined by pairs of guard cells that perceive and transduce external signals, leading to cellular volume changes and consequent stomatal apertur...

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...

MetabolomicsA systems analysis with “simplified source-sink model” reveals metabolic reprogramming in a pair of source-to-sink organs during early fruit development in tomato by LED light treatments
Tomato (Solanum lycopersicum) is a model crop for studying development regulation and ripening in flesh fruits and vegetables. Supplementary light to maintain the optimal light environment can lead to the stable growth of tomatoes in greenhouses and areas without sufficient daily light integral. Tec...

MetabolomicsMetabolite control of enzyme activity links stress to biosynthetic regulation

Cells must continuously adjust metabolic output to maintain homeostasis under changing environmental conditions, yet the mechanisms that enable rapid and reversible control of pathway activity remain largely unknown. The methylerythritol phosphate (MEP) pathway, of bacterial origin and conserved ...

MetabolomicsMolecular characterization of firefly nuptial gifts: a multi-omics approach sheds light on postcopulatory sexual selection
Postcopulatory sexual selection is recognized as a key driver of reproductive trait evolution, including the machinery required to produce endogenous nuptial gifts. Despite the importance of such gifts, the molecular composition of the non-gametic components of male ejaculates and their interactions...

ProteomicsDynamic regulation of the proteome and lysine acetylome of Chlamydomonas reinhardtii in dependence on light and acetate
Here, we performed a mass spectrometry-based analysis to study lysine acetylation and proteome dynamics in Chlamydomonas under varying growth conditions. Liquid cultures of Chlamydomonas were transferred from mixotrophic (light and acetate as carbon source) to heterotrophic (dark and acetate), or ph...

MetabolomicsClock regulation of metabolites reveals coupling between transcription and metabolism
The circadian clock is intricately connected with metabolism, however the precise details of these connections are incomplete. Here we used high temporal resolution metabolite profiling to determine circadian regulation of mouse liver and cell autonomous metabolism. In mouse liver, we found ~50% of ...

MetabolomicsMicroRNA-mediated regulation of lipid metabolism in virus-infected Emiliania huxleyi.
The interactions between Emiliania huxleyi and E. huxleyi virus (EhV) regulate marine carbon and sulfur biogeochemical cycles and play a prominent role in global climate change. As a large DNA virus, EhV has developed a novel 'virocell metabolism' model to meet its high metabolic needs. Although it ...
