MetabolomicsJasmonate-mediated stomatal closure under elevated CO2 revealed by time-resolved metabolomics
Foliar stomatal movements are critical for regulating plant water loss and gas exchange. Elevated carbon dioxide (CO2) levels are known to induce stomatal closure. However, the current knowledge on CO2 signal transduction in stomatal guard cells is limited. Here we report metabolomic responses of Br...

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...

TranscriptomicsA transcriptional map following the developmental trajectory of the Arabidopsis stomatal lineage
Developmental transitions can be described in terms of morphology and individual genes expression patterns, but also in terms of global transcriptional and epigenetic changes. Most of the large-scale studies of such transitions, however, have only been possible in synchronized cell culture systems. ...

TranscriptomicsMolecular profiling of stomatal lineage cell states
We initiated a study to investigate the transcriptional profiles associated with cell states of the stomatal lineage. A stem-cell like precursor of stomata, a meristemoid. reiterates asymmetric divisions and renews itself before differentiating into guard cells. The transient and asynchronous nature...

TranscriptomicsArabidopsis Me-0 vs tetraploid Col
To investigate gene expression differences related to the regulation of stomatal aperture between two Arabidopsis accessions, Me-0 and tetraploid Col, we performed microarray analysis on guard cell protoplasts from these two accessions. We identified 1,777 probes as up-regulated and 1,706 probes as ...

GenomicsDirect roles of SPEECHLESS in the specification of stomatal self-renewing cells [ChIP-Seq]
Lineage-specific stem cells are critical for the production and maintenance of specific cell types and tissues in multicellular organisms. In higher plants, the initiation and proliferation of stomatal stem cells is controlled by the basic helix-loop-helix transcription factor SPEECHLESS (SPCH). The...

ProteomicsCo-Immunoprecipitation of transcriptional regulators of stomatal development in B. distachyon
Stomata are pores in the epidermis of plants that can open and close and allow for gas exchange vital for photosynthesis and regulate transpiration. Stomatal development is driven by a set of conserved bHLH transcription factors (SPCH, MUTE, FAMA, and their heterodimerization partners ICE1, SCRM2), ...
