2014年1月1日 · H 2 O 2 plays an important role in plants, which may control many different physiological responses such as biotic and abiotic stress-response and systemic signaling.

2018年9月17日 · Hydrogen peroxide (H 2 O 2) is produced, via superoxide and superoxide dismutase, by electron transport in chloroplasts and mitochondria, plasma membrane NADPH oxidases, peroxisomal oxidases, type III peroxidases and other apoplastic oxidases.

2020年8月1日 · Hydrogen peroxide acts as a significant signalling and regulatory component interrelated with signal transduction in plants. H 2 O 2 at nanomolar levels facilitates seed germination, chlorophyll content, stomatal opening, flowering and delays senescence.

2023年1月1日 · Hydrogen peroxide (H 2 O 2) is a molecule generated by plant cells during vital processes such as photosynthesis and photorespiration. This molecule is required for plant development and growth, as well as for coordinating appropriate responses to survive in a changing climate.

2008年1月7日 · This review describes various aspects of H 2 O 2 function, generation and scavenging, gene regulation and cross-links with other physiological molecules during plant growth, development and resistance responses.

2018年9月18日 · In this review, we summarize hydrogen peroxide metabolism in plants, the sources and sinks of this compound and its transport via peroxiporins. We outline H 2 O 2 perception, its direct and indirect effects and known targets in the transcriptional machinery.

2023年5月12日 · In plants H 2 O 2 is produced as a by-product of oxidative metabolism (Mittler 2002). Plants can either produce H 2 O 2 through enzymatic or non-enzymatic means. In plant cells, H 2 O 2 is produced via a variety of mechanisms, including redox reactions, electron transport chains (ETC) and photorespiration.

2011年1月1日 · Hydrogen peroxide (H2O2) is continuously produced as a by-product of oxidative plant aerobic metabolism. It plays a dual role in cells. Under normal conditions, H2O2 acts as a key regulator of many biological processes because H2O2 have been identified as an...

2019年3月29日 · Nitric oxide (NO) and hydrogen peroxide (H 2 O 2) in plant cells participate in complex processes both under physiological conditions (seed and pollen germination, plant development and growth, stomatal movement, leaf senescence, fruit ripening, and others) and in the mechanism of response against biotic and abiotic stresses. They play their ...

Hydrogen peroxide (H2O2) is produced predominantly in plant cells during photosynthesis and photorespiration, and to a lesser extent, in respiration processes. It is the most stable of the so-called reactive oxygen species (ROS), and therefore plays a …
