Stomatal pores in plant leaves mediate CO 2 uptake for photosynthesis and water loss via transpiration. Altered stomatal density can affect plant photosynthetic capacity, water use efficiency, and growth, potentially providing either benefits or drawbacks depending on the environment. Here we explore, at different air humidity regimes, gas exchange...

Stomatal pores that control plant CO2 uptake and water loss affect global carbon and water cycles. In the era of increasing atmospheric CO2 levels and vapor pressure deficit (VPD), it is essential to understand how these stimuli affect stomatal behavior. Whether stomatal responses to sub-ambient and above-ambient CO2 levels are governed by the same...

Stomatal pores that control plant CO 2 uptake and water loss affect global carbon and water cycles. In the era of increasing atmospheric CO 2 levels and vapor pressure deficit (VPD), it is essential to understand how these stimuli affect stomatal behaviour. It is unknown whether stomatal responses to sub-ambient and above-ambient CO 2 levels are go...

Respiration in leaves and the continued elevation in the atmospheric CO2 concentration cause CO2‐mediated reduction in stomatal pore apertures. Several mutants have been isolated for which stomatal responses to both abscisic acid (ABA) and CO2 are simultaneously defective. However, there are only few mutations that impair the stomatal response to e...
