“…Exogenous H 2 O 2 (millimolar equivalent) has been shown to inhibit stomatal opening by signaling the production of NO in guard cells (79,80). Furthermore, as peroxides are potent oxidizers and generators of reactive oxygen species (ROS) like the hydroxyl radical (OH) and the superoxide (O 2 .− ) in water, their large deposition flux motivates inquiries into their fates at the surface of plants.…”

We report fluxes and dry deposition velocities for 16 atmospheric compounds above a southeastern United States forest, including: hydrogen peroxide (H 2 O 2 ), nitric acid (HNO 3 ), hydrogen cyanide (HCN), hydroxymethyl hydroperoxide, peroxyacetic acid, organic hydroxy nitrates, and other multifunctional species derived from the oxidation of isoprene and monoterpenes. The data suggest that dry deposition is the dominant daytime sink for small, saturated oxygenates. Greater than 6 wt %C emitted as isoprene by the forest was returned by dry deposition of its oxidized products. Peroxides account for a large fraction of the oxidant flux, possibly eclipsing ozone in more pristine regions. The measured organic nitrates comprise a sizable portion (15%) of the oxidized nitrogen input into the canopy, with HNO 3 making up the balance. We observe that water-soluble compounds (e.g., strong acids and hydroperoxides) deposit with low surface resistance whereas compounds with moderate solubility (e.g., organic nitrates and hydroxycarbonyls) or poor solubility (e.g., HCN) exhibited reduced uptake at the surface of plants. To first order, the relative deposition velocities of water-soluble compounds are constrained by their molecular diffusivity. From resistance modeling, we infer a substantial emission flux of formic acid at the canopy level (∼1 nmol m −2 ·s −1 ). GEOS−Chem, a widely used atmospheric chemical transport model, currently underestimates dry deposition for most molecules studied in this work. Reconciling GEOS−Chem deposition velocities with observations resulted in up to a 45% decrease in the simulated surface concentration of trace gases.biosphere−atmosphere exchange | isoprene | dry deposition | OVOCs | fluxes

“…6, A and B). Nitro-L-Arg methyl ester inhibits H 2 O 2 -mediated NO generation in guard cells of P. aureus and V. faba, implying that NOS activity is related to H 2 O 2 -mediated NO generation (Lum et al, 2002;He et al, 2005). However, using Arabidopsis Atnoa1 and nia1, nia2 mutants, Bright et al (2006) reported that it is NR, not AtNOA1, that is responsible for the stomatal closure and NO generation in guard cells in response to H 2 O 2 , although Desikan et al (2002) showed that stomatal closure in the nia1, nia2 double mutant was induced by H 2 O 2 as in the wild type.…”

A Signaling Pathway Linking Nitric Oxide Production to Heterotrimeric G Protein and Hydrogen Peroxide Regulates Extracellular Calmodulin Induction of Stomatal Closure in Arabidopsis

Extracellular calmodulin (ExtCaM) regulates stomatal movement by eliciting a cascade of intracellular signaling events including heterotrimeric G protein, hydrogen peroxide (H 2 O 2 ), and Ca 2+ . However, the ExtCaM-mediated guard cell signaling pathway remains poorly understood. In this report, we show that Arabidopsis (Arabidopsis thaliana) NITRIC OXIDE ASSOCIATED1 (AtNOA1)-dependent nitric oxide (NO) accumulation plays a crucial role in ExtCaM-induced stomatal closure. ExtCaM triggered a significant increase in NO levels associated with stomatal closure in the wild type, but both effects were abolished in the Atnoa1 mutant. Furthermore, we found that ExtCaM-mediated NO generation is regulated by GPA1, the Ga-subunit of heterotrimeric G protein. The ExtCaM-dependent NO accumulation was nullified in gpa1 knockout mutants but enhanced by overexpression of a constitutively active form of GPA1 (cGa). In addition, cGa Atnoa1 and gpa1-2 Atnoa1 double mutants exhibited a similar response as did Atnoa1. The defect in gpa1 was rescued by overexpression of AtNOA1. Finally, we demonstrated that G protein activation of NO production depends on H 2 O 2 . Reduced H 2 O 2 levels in guard cells blocked the stomatal response of cGa lines, whereas exogenously applied H 2 O 2 rescued the defect in ExtCaM-mediated stomatal closure in gpa1 mutants. Moreover, the atrbohD/F mutant, which lacks the NADPH oxidase activity in guard cells, had impaired NO generation in response to ExtCaM, and H 2 O 2 -induced stomatal closure and NO accumulation were greatly impaired in Atnoa1. These findings have established a signaling pathway leading to ExtCaM-induced stomatal closure, which involves GPA1-dependent activation of H 2 O 2 production and subsequent AtNOA1-dependent NO accumulation.Plant guard cells control opening and closure of the stomata in response to phytohormones (e.g. abscisic acid [ABA]) and various environmental signals such as light and temperature, thereby regulating gas exchange for photosynthesis and water status via transpiration . Cytosolic calcium ([Ca 2+ ] i ) has been shown to be a key second messenger that changes in response to multiple stimuli in guard cells (McAinsh et al., 1995;Grabov and Blatt, 1998;Wood et al., 2000). A large proportion of Ca 2+ is localized in extracellular space. It has been shown that external Ca 2+ concentration ([Ca 2+ ] o ) promotes stomatal closure and induces oscillation in [Ca 2+ ] i in guard cells (MacRobbie, 1992;McAinsh et al., 1995;Allen et al., 2001 Calmodulin is a well-known Ca 2+ sensor that is activated upon binding of Ca 2+ . It has been shown that calmodulin exists not only intracellularly but also extracellularly in many plant species
