Plants adapt their water consumption to environmental conditions by counting and calculating environmental stimuli with their guard cells. Plants control their water consumption via adjustable pores ...

Stomata are microscopic pores on the leaf surface that regulate gas exchange and water loss, balancing CO2 uptake for photosynthesis with transpiration. Each pore is flanked by a pair of guard cells ...

Scientists have uncovered how the interplay between cell shape and mechanical stress influences the orientation of stomata ...

Using optogenetics, researchers have detected a new acid sensor in plant cells that is addressing a cell-internal calcium store. When plants are infected by pathogens, suffer from a lack of water or ...

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 ...
