In a first, scientists have designed immune cells that protect stem cell transplants from being rejected by the body — and they could someday open the door for a cure for diabetes. The new cells, ...

Beyond controlling stomatal (tiny pores for gas exchange) guard cells, FAMA also helps to produce myrosin cells—the specialized structures that store mustard oil compounds. So, when a plant is ...

Because of these properties, the majority of plant gas exchange occurs through stomata. Consequently, composition of cuticle and fast guard cell signaling are thought to be the major factors limiting ...

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 ...
