Plant stomata pressure dynamics illuminated by laser-based method offer water efficiency insights

Summary by Phys.org
Every time the temperature drops, a cloud passes overhead, or the sun sets, a plant makes a choice: Keep its microscopic pores, called stomata, open to absorb carbon dioxide and continue photosynthesizing or close them to protect its precious stores of water. That capacity to open and close pores requires the plant to respond to subtle environmental changes by adjusting the pressure within the cells of the stomata—a complex ability that plants e…

The Genetic Secret Behind Wasabi's Defensive Kick

Plants in the cabbage family didn’t intend to be so tasty. The taste is part of a defence against herbivores. Now scientists in Japan have found the genes for this defence are repurposed genes that originally controlled stomata, the pores in leaves that plants “breathe” through. Opening and closing of stomata for gas exchange depends on guard cells that guard the holes in a leaf. They’re very different to myrosin cells, the cells that help creat…
