Recent biochemical and genetic studies confirm that hydrogen peroxide is a signalling molecule in plants that mediates responses to abiotic and biotic stresses. Signalling roles for hydrogen peroxide during abscisic-acid-mediated stomatal closure, auxin-regulated root gravitropism and tolerance of oxygen deprivation are now evident. The synthesis and action of hydrogen peroxide appear to be linked to those of nitric oxide. Downstream signalling events that are modulated by hydrogen peroxide include calcium mobilisation, protein phosphorylation and gene expression. Calcium and Rop signalling contribute to the maintenance of hydrogen peroxide homeostasis.

Anthocyanin Function in Vegetative Organs (2008, background): “H2O2 is considered a particularly important molecule in plant signalling because of its relative stability, as well as its ability to diffuse rapidly across membranes and between different cell compartments (Droge 2002; Neill et al. 2002a ).”
The role of the mitochondrion in plant responses to biotic stress (2007, neutral): “…(ROS) (particularly H2O2) increase in abundance following pathogen recognition and each are important signaling molecules that promote and coordinate defense and HR responses (Alvarez 2000, Delledonne 2005, Laloi et al. 2004, Neill et al. 2002, Torres and Dangl 2005, Wendehenne et al. 2004).”
Temperature stress and redox homeostasis in agricultural crops (2015, background): “…of plant maturation and senescence (Mishina et al., 2007), suppression of floral transition (He et al., 2004), ethylene emission and stomatal closure (Garcia-Mata and Lamattina, 2002; Neill et al., 2002; Guo et al., 2003), programmed cell death and light-mediated greening (Zhang et al., 2006).”
The role of ABA and MAPK signaling pathways in plant abiotic stress responses.

Ethylene-induced stomatal closure in Arabidopsis occurs via AtrbohF-mediated hydrogen peroxide synthesis. (2006, background): “H2O2 is a signalling molecule of widespread importance in plant responses to various biotic and abiotic stimuli that include pathogen challenge, drought stress, exposure to atmospheric pollutants, extremes of temperatures, gravitropism, hormones, cell development and senescence (Apel and Hirt, 2004;”
Hydrogen Peroxide and Plant Stress: A Challenging Relationship (2007, background): “That is, sensing was a result of oxidation of the thiol groups by H2O2 and other ROS, including NO, perhaps even involving competition of the two types of oxidants for the same modification sites (see also Foyer et al. 1997; Neill et al. 2002).”
Beneficial effects of silicon nutrition in alleviating salinity stress in hydroponically grown canola, Brassica napus L., plants (2010, background): “Salt stress through an increase in reactive oxygen species (ROS), such as singlet oxygen, superoxide anion (O2· )), hydrogen peroxide (H2O2) and hydroxyl radical (OH·), also leads to oxidative stress (Alscher et al. 1997; Mittler 2002; Neill et al. 2002).”
ABA-induced NO generation and stomatal closure in Arabidopsis are dependent on H2 O2 synthesis. (2006, background): “…hydrogen peroxide (H2O2) have emerged as ubiquitous components of signal transduction pathways, controlling a diverse range of physiological functions in a wide spectrum of biological systems (Durner and Klessig, 1999; Finkel and Holbrook, 2000; Neill et al., 2002a, 2003; Wendehenne et al., 2004).”
