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...

MetabolomicsMetabolomic Responses of Arabidopsis Suspension Cells to Bicarbonate under Light and Dark Conditions
Global CO2 level presently recorded at 400 ppm is expected to reach 550 ppm in 2050, an increment likely to impact plant growth and productivity. Using targeted LC-MS and GC-MS platforms we quantified 229 and 29 metabolites, respectively in a time-course study to reveal short-term responses to diffe...

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...

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...

MetabolomicsMetabolomic Profile of Diet-Induced Obesity Mice in Response to Human and Small Humanin-like Peptide 2 Treatment

INTRODUCTION: The mitochondrial-derived peptides (MDPs) are a novel group of natural occurring peptides that have important signaling functions and biological activity. Both humanin and small-humanin-like peptide 2 (SHLP2) have been reported to act as insulin sensitizers and modu...

MetabolomicsDual transcriptomic & metabolomic analysis of elicited flax sheds light on the kinetics of immune defense activation against the biotrophic pathogen Oidium lini.
Flax (Linum usitatissimum) grown under controlled conditions displayed genotype-dependent resistance to powdery mildew (Oidium lini) following COS-OGA (comprising chitosan- and pectin-derived oligomers) elicitor application. The present study reveals a two-step immune response in plant...

TranscriptomicsAcute effects of light on alternative splicing in light-grown plants
We report the results of a genome-wide analysis of AS in Arabidopsis thaliana plants exposed to a 2h light pulse given in the middle of the night, a treatment that simulates the effects of early dawn or late dusk signals. This light affects the plant transcriptome at multiple regulatory layers, and...

TranscriptomicsMolecular Rejuvenation of Gene Expression Pattern of Photoaged and Intrinsically Aged Human Skin by Broadband Light Treatment
Studies in model organisms suggest that aged cells can be functionally rejuvenated, but whether this concept applies to human skin is unclear. Here we apply deep sequencing of RNA 3' ends ("3-seq") to discover the gene expression program associated with human photoaging and intrinsic skin ...
