DOI: 10.1038/s41467-017-01237-5
Abstract: Stomata regulate gas exchange between plants and atmosphere by integrating opening and closing signals. Stomata open in response to low CO2 concentrations to maximize photosynthesis in the light; however, the mechanisms that coordinate photosynthesis and… read more here.

DOI: 10.1038/s41467-022-28263-2
Abstract: Stomatal opening requires the provision of energy in the form of ATP for proton pumping across the guard cell (GC) plasma membrane and for associated metabolic rearrangements. The source of ATP for GCs is a… read more here.

DOI: 10.1038/s41467-024-45236-9
Abstract: Plasma membrane H+-ATPase provides the driving force for light-induced stomatal opening. However, the mechanisms underlying the regulation of its activity remain unclear. Here, we show that the phosphorylation of two Thr residues in the C-terminal… read more here.

DOI: 10.1038/s41598-021-04433-y
Abstract: Stomata are epidermal pores formed by pairs of specialized guard cells, which regulate gas exchanges between the plant and the atmosphere. Modulation of transcription has emerged as an important level of regulation of stomatal activity.… read more here.

DOI: 10.1093/jxb/eraa073
Abstract: Abstract The glucosinolate–myrosinase system is a well-known defense system that has been shown to induce stomatal closure in Brassicales. Isothiocyanates are highly reactive hydrolysates of glucosinolates, and an isothiocyanate, allyl isothiocyanate (AITC), induces stomatal closure… read more here.

DOI: 10.1093/jxb/eraf040
Abstract: Abstract Organisms adapt to predictable environmental changes via a biological mechanism called priming. Phototropin is a plant-specific blue light photoreceptor that mediates daily light-induced responses, such as chloroplast relocation, stomatal opening, and phototropism, to optimize… read more here.

DOI: 10.1093/jxb/erz563
Abstract: Abstract Plants experience changes in light intensity and quality due to variations in solar angle and shading from clouds and overlapping leaves. Stomatal opening to increasing irradiance is often an order of magnitude slower than… read more here.

DOI: 10.1093/pcp/pcaf050
Abstract: Abstract Phosphorylation of the penultimate residue, threonine (pen-Thr), of plasma membrane (PM) H+-ATPase is essential for its activation and blue light (BL)-induced stomatal opening. However, the regulatory mechanism of action of PM H+-ATPase pen-Thr phosphorylation… read more here.
