Cruciferous plants' pungent defense mechanism: How repurposed stomatal genes also fend off herbivores
Throughout evolution, plants have continuously adapted to survive in changing environments. Apart from complex structural ...
Plants 'breathe' with millions of tiny mouths—lasers illuminate evolution of stomata behavior
Plant behavior may seem rather boring compared with the frenetic excesses of animals. Yet the lives of our vegetable friends, ...

Optogenetic method shows plant guard cells can count environmental stimuli to adapt water consumption
More information: Shouguang Huang et al, Guard cells count the number of unitary cytosolic Ca 2+ signals to regulate stomatal dynamics, Current Biology (2024). DOI: 10.1016/j.cub.2024.07.086 ...

Adaptations of the leaf
It moves by diffusion through small holes in the underside of the leaf called stomata. Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or ...

Coming closer to a stoma ion channel
Gas exchange between the plant and the atmosphere takes place through the stomata, which consist in two bean-shaped guard cells surrounding a pore. (a) Malate and Cl − efflux from the guard ...
