… At low pH gradients V-ATPases transport several H + ions per ATP, but the coupling ratio
drops if H + has to be transported against a higher pH gradient across the vacuolar membrane. …

Plants grow and reproduce within a highly dynamic environment that can see abrupt changes
in conditions, such as light intensity, temperature, humidity, or interactions with biotic …

… (2014a) studied the properties of ABA import into yeast and root cells and concluded that
diffusion of ABA-H is not the dominant transport mechanism of ABA there. Be that as it may, …

… We measured stomatal responses to ABA, hydrogen peroxide (H 2 O 2 ), NO and repetitive
Ca 2+ pulses (Fig. 3). Stomata of slac1 mutants showed a strong insensitivity to ABA (Fig. …

… Among these, H 2 O 2 is not very toxic to plants cells, which are capable of detoxifying
substantial amounts of it. However, formation of hydroxyl radicals in the apoplast from …

Abscisic acid ( ABA ) is a key hormone for plant growth, development, and stress adaptation.
Perception of ABA through four types of receptors has been reported. We show here that …

The air pollutant ozone can be used as a tool to unravel in planta processes induced by reactive
oxygen species (ROS). Here, we have utilized ozone to study ROS‐dependent stomatal …

… Photosynthetic photon flux was 400 µmol m–2 s–1, photoperiod was 12 h and relative …
lasted for 4 h per day. The total ozone dose at the end of the experiment was 2.8 ppm h–1. Ozone …

Experiments with several Arabidopsis thaliana mutants have revealed a web of interactions
between hormonal signaling. Here, we show that the Arabidopsis mutant radical-induced …

… mmol H 2 O per m 2 per s per min for Col‐0 wild‐type plants and −0.035±0.008 mmol H 2 O
… ±0.013 mmol H 2 O per m 2 per s per min for Col‐0 wild‐type plants and 0.022±0.002 mmol …
