“…Cui B, et al [2] reported that the level of NO is significant for setting up basal resistance against Phytophthora parasitica in Arabidopsis. Moreover, transformations in S-nitrosoglutathione Reductase 1 (GSNOR1) impair both SA and Reactive Oxygen Species (ROS) amassing, driving to improved helplessness towards P. parasitica.…”

Nitric oxide (NO) may be a diatomic gaseous atom, which plays distinctive parts completely different strata of life forms. Found as a neurotransmitter in creatures, presently picked up a significant place in plant signaling cascade. NO as a key molecular signal that takes an interest within the direction of a few physiological forms in specific, it features a critical part in plant resistance to pathogens by activating resistance related cell passing and by contributing to the nearby and systemic acceptance of protection qualities. NO invigorates flag transduction pathways through protein kinases, cytosolic Ca2+ mobilization and protein alteration (i.e., nitrosylation). S-nitrosylation can balance the work of target proteins, empowering responsiveness to cellular redox changes [1].

“…SA modulates the biosynthesis of auxin/JA and antagonizes their signaling in pathogenesis responses (Vlot et al., 2009). SA also mediates NO synthesis to regulate stomatal conductance by integrating into the Ca 2+ /CPK‐dependent ABA signaling pathway (Cui et al., 2021; Prodhan et al., 2018; Zottini et al., 2007). In addition, it is required for optimal photosynthesis and redox homeostasis (Mateo et al., 2006).…”

SUMMARY The homeostasis of hydrogen peroxide (H2O2), a key regulator of basic biological processes, is a result of the cooperation between its generation and scavenging. However, the mechanistic basis of this balance is not fully understood. We previously proposed that the interaction between glycolate oxidase (GLO) and catalase (CAT) may serve as a molecular switch that modulates H2O2 levels in plants. In this study, we demonstrate that the GLO–CAT complex in plants exists in different states, which are dynamically interchangeable in response to various stimuli, typically salicylic acid (SA), at the whole‐plant level. More crucially, changes in the state of the complex were found to be closely linked to peroxisomal H2O2 fluctuations, which were independent of the membrane‐associated NADPH oxidase. Furthermore, evidence suggested that H2O2 channeling occurred even in vitro when GLO and CAT worked cooperatively. These results demonstrate that dynamic changes in H2O2 levels are physically created via photorespiratory metabolic channeling in plants, and that such H2O2 fluctuations may serve as signals that are mechanistically involved in the known functions of photorespiratory H2O2. In addition, our study also revealed a new way for SA to communicate with H2O2 in plants.
