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 ...

In all experiments, stomata incubated at low (10 °C) temperatures on 5.6 × 10-4 M ABA showed wider apertures than those incubated on distilled water. This ABA-stimulated stomatal opening was ...

SLAC/SLAH-type anion channels in the guard cells are of central importance for the regulation of the stomata. This has been ...

How do plants breathe through stomata? Key regulators of stomata are plant vacuoles, fluid-filled organelles bound by a single membrane called the tonoplast. Plant vacuoles are fluid-filled ...

the structure and development of stomata; the measurement of stomatal aperture and conductance; the ion exchanges and metabolism of guard cells; work on isolated guard-cell protoplasts; the responses ...

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 ...

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 ...
