Two highly specialized cells, the guard cells that surround the stomatal pore, are able to
integrate environmental and endogenous signals in order to control the stomatal aperture …

▪ Abstract Acid soils significantly limit crop production worldwide because approximately
50% of the world's potentially arable soils are acidic. Because acid soils are such an …

▪ Abstract The rhizosphere is the zone of soil immediately surrounding plant roots that is
modified by root activity. In this critical zone, plants perceive and respond to their …

Aluminum (Al) toxicity is the primary factor limiting crop production on acidic soils (pH values
of 5 or below), and because 50% of the world's potentially arable lands are acidic, Al toxicity …

▪ Abstract Guard cells surround stomatal pores in the epidermis of plant leaves and stems.
Stomatal pore opening is essential for CO2 influx into leaves for photosynthetic carbon …

Natural inputs of chlorine (Cl) to soils come mainly from rainwater, sea spray, dust and air
pollution. In addition, human practices, such as irrigation and fertilization, contribute …

Because plant wilting has been described as a consequence of cadmium (Cd2+) toxicity, we
investigate Cd2+ effects on plant water losses, gas exchanges and stomatal behaviour in …

Guard cells are located in the epidermis of plant leaves, and in pairs surround stomatal
pores. These control both the influx of CO2 as a raw material for photosynthesis and water …

The phytohormone abscisic acid (ABA) is the best‐known stress signaling molecule in
plants. ABA protects sessile land plants from biotic and abiotic stresses. The conserved …

Abscisic acid (ABA) is a well-studied regulator of stomatal movement. Hydrogen sulfide
(H2S), a small signaling gas molecule involved in key physiological processes in mammals …
