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 ...

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’ ...

In 2011, The Scientist featured Bergmann’s early work on stomata development. She now uses new omics tools to explore the ...

Plant researchers have a potent new tool at disposal: A research team now shows how to close the stomata of leaves using light pulses. Plants have microscopically small pores on the surface of their ...

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 ...
