Left: A blue light pulse of 0.1 seconds triggers a calcium signal (red) in guard cells, which is followed by an anion current (black). Right: The influx of calcium into the cell promotes the release ...

We have investigated the cellular basis for the effects of oxidative stress on stomatal behavior using stomatal bioassay and ratio photometric techniques. Two oxidative treatments were employed in ...

Scientists from Nagoya University and The University of Texas at Austin have unraveled a key mystery in the formation of stomatal cells in plants. Stomata are the holes on the surface of plants’ ...

The paper M. Papanatsiou et al., “Optogenetic manipulation of stomatal kinetics improves carbon assimilation, water use, and growth,” Science, 363:1456–59, 2019. In plants, guard cells control the ...

Plants optimize carbon assimilation while limiting water loss by adjusting stomatal aperture. In grasses, a developmental innovation—the addition of subsidiary cells (SCs) flanking two dumbbell-shaped ...

To test whether speed of stomata opening and closing can increase productivity and water use efficiency, researchers added the synthetic light-activated BLINK1 ion channel to guard cells in ...

Whether Guard Cells (GCs) carry out photosynthesis has been debated for decades. Earlier studies suggested that guard cell chloroplasts (GCCs) cannot fix CO2 but later studies argued otherwise. Until ...
