“…More specifically, NOS uses two co-substrates, molecular oxygen and nicotinamide adenine dinucleotide phosphate (NADPH), to catalyze the oxidation of the guanidine nitrogen of L-arginine. The intermediate product of five-electron oxidation is N-hydroxy-L-arginine [31,32]. The active human NOS isoforms are neuronal NOS (nNOS), endothelial NOS (eNOS), and inducible NOS (iNOS).…”

Nitric oxide (NO) is an important signaling molecule that is involved in a wide range of physiological processes in plants, including responses to biotic and abiotic stresses. Changes in endogenous NO concentration lead to activation/deactivation of NO signaling and NO-related processes. This paper presents the current state of knowledge on NO biosynthesis and scavenging pathways in plant cells and highlights the role of NO in post-translational modifications of proteins (S-nitrosylation, nitration, and phosphorylation) in plants under optimal and stressful environmental conditions. Particular attention was paid to the interactions of NO with other signaling molecules: reactive oxygen species, abscisic acid, auxins (e.g., indole-3-acetic acid), salicylic acid, and jasmonic acid. In addition, potential common patterns of NO-dependent defense responses against attack and feeding by parasitic and molting Ecdysozoa species such as nematodes, insects, and arachnids were characterized. Our review definitely highlights the need for further research on the involvement of NO in interactions between host plants and Ecdysozoa parasites, especially arachnids.

“…Nitric oxide (NO) is a gaseous signaling molecule originated mainly from the nitrate metabolism in plants through nitrate/nitrite reductase activities ( Salgado et al, 2009 ; Salgado et al, 2017 ). NO plays a broad role in the regulation of developmental processes in plants ( Mur et al, 2013 ).…”

An overview of the total Arabidopsis thaliana transcriptome, described previously by our research group, pointed some noncoding RNA (ncRNA) as participants in the restoration of hair-root phenotype in A. thaliana rhd6 mutants, leading us to a deeper investigation. A transcriptional gene expression profiling of seedling roots was performed aiming to identify ncRNA responsive to nitric oxide (GSNO) and auxin (IAA), and their involvement in root hair formation in the rhd6 null mutant. We identified 3,631 ncRNAs, including new ones, in A. thaliana and differential expression (DE) analysis between the following: 1) GSNO-treated rhd6 vs. untreated rhd6, 2) IAA-treated rhd6 vs. untreated rhd6, 3) GSNO-treated rhd6 vs. IAA-treated rhd6, and 4) WS-2 vs. untreated rhd6 detected the greatest number of DE genes in GSNO-treated rhd6. We detected hundreds of in silico interactions among ncRNA and protein-coding genes (PCGs), highlighting MIR5658 and MIR171 precursors highly upregulated in GSNO-treated rhd6 and wild type, respectively. Those ncRNA interact with many DE PCGs involved in hormone signaling, cell wall development, transcription factors, and root hair formation, becoming candidate genes in cell wall modulation and restoration of root hair phenotype by GSNO treatment. Our data shed light on how GSNO modulates ncRNA and their PCG targets in A. thaliana root hair formation.
