MetabolomicsMetabolomic Responses of Guard Cells and Mesophyll Cells to Bicarbonate
Anthropogenic CO2 presently at 400 ppm is expected to reach 550 ppm in 2050, an increment expected to affect plant growth and productivity. Paired stomatal guard cells (GCs) are the gate-way for water, CO2, and pathogen, while mesophyll cells (MCs) represent the bulk cell-type of green leaves mainly...

MetabolomicsCell type-specific proteomics uncovers a RAF15-SnRK2.6/OST1 kinase cascade in guard cells

Multicellular organisms such as plants contain various cell types with specialized functions. Analyzing the characteristics of each cell type reveals specific cell functions and enhances our understanding of organization and function at the organismal level. Guard cells (GCs) are specialized epid...

TranscriptomicsSucrose modulation of the Arabidopsis thaliana guard-cell transcriptome
Microarrays were used to evaluate the effect of sucrose on gene expression in guard cells. Strips of Arabidopsis leaves were incubated with sucrose or mannitol or no sugars, then the leaves were freeze dried and guard cells were dissected from the leaf strips and analyzed. RNA was extracted from gu...

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...

TranscriptomicsAgilent data from Arabidopsis thaliana enriched guard cell tissue and leafs.
To identify genes of the guard cell transcriptome of Arabidopsis thaliana enriched guard cell samples were compared with total leaf tissue. Genes of the abscisic acid and humidity response of Arabidopsis thaliana guard cells were identified by treatment with ABA-Spray and low humidity. total samples...

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...

ProteomicsGuard cell proteome - Dawn regulates guard cell proteins in Arabidopsis thaliana that function in ATP production from fatty acid beta-oxidation
Proteome changes that happen in the guard cells during dawn were up till now poorly described. Bad accessibility to pure and intact guard cell samples can be considered as the primary reason behind this lack of knowledge. By elucidating the identities of enzymes that change in abundance by the trans...

MetabolomicsMesenchymal stromal cells secretome restores bioenergetic and redox homeostasis in human proximal tubule cells after ischemic injury

BACKGROUND: Ischemia/reperfusion injury (IRI) is the leading cause of acute kidney injury (AKI). The current standard of care focuses on supporting kidney function, stating the need for more efficient and targeted therapies to enhance repair. Mesenchymal Stromal Cells (MSCs) and ...

ProteomicsIdentification of DIR1-dependant cellular responses required for systemic acquired resistance in guard cells
After localized invasion by bacterial pathogens, systemic acquired resistance (SAR) is induced in uninfected plant tissues, resulting in enhanced defense against a broad range of pathogens. Although SAR requires mobilization of signaling molecules via the plant vasculature, the specific mechanisms r...
