Airway Thiol-NO Adducts as Determinants of Exhaled NO

Antioxidants, 2021
Thiol-NO adducts such as S-nitrosoglutathione (GSNO) are endogenous bronchodilators in human airways. Decreased airway S-nitrosothiol concentrations are associated with asthma. Nitric oxide (NO), a breakdown product of GSNO, is measured in exhaled breath

Proteomic Analysis of S-Nitrosation Sites During Somatic Embryogenesis in Brazilian Pine, Araucaria angustifolia (Bertol.) Kuntze

Frontiers in Plant Science, 2022
Cysteine S-nitrosation is a redox-based post-translational modification that mediates nitric oxide (NO) regulation of various aspects of plant growth, development and stress responses.

Nitric oxide and reactive oxygen species mediate metabolic changes in barley seed embryo during germination

Frontiers in Plant Science, 2016
The levels of nitric oxide (NO) and reactive oxygen species (ROS), ATP/ADP ratios, reduction levels of ascorbate and glutathione, expression of the genes encoding proteins involved in metabolism of NO and activities of the enzymes involved in ...

S-nitrosoglutathione reductases are low-copy number, cysteine-rich proteins in plants that control multiple developmental and defense responses in Arabidopsis.

Frontiers in Plant Science, 2013
S-nitrosoglutathione reductase (GSNOR) is believed to modulate effects of reactive oxygen and nitrogen species through catabolism of S-nitrosoglutathione (GSNO).

Suboptimal zinc supply affects the S-nitrosoglutathione reductase enzyme and nitric oxide signaling in Arabidopsis

Plant Stress, 2023
The S-nitrosoglutathione reductase (GSNOR), a key regulator of nitric oxide (NO) signaling, requires zinc (Zn) cofactors for its catalytic activity. Possible changes in GSNOR function and NO signaling due to limited Zn supply and participation of GSNOR ...

GSNOR provides plant tolerance to iron toxicity via preventing iron-dependent nitrosative and oxidative cytotoxicity

Nature Communications, 2019
How plants deal with iron toxicity is still unclear. Here, the authors reveal that S-nitrosoglutathione-reductase (GSNOR) provides tolerance to iron toxicity by preventing iron-dependent nitrosative and oxidative cytotoxicity in Arabidopsis, legumes, and

Strigolactones Interact With Nitric Oxide in Regulating Root System Architecture of Arabidopsis thaliana

Frontiers in Plant Science, 2020
Both nitric oxide (NO) and strigolactone (SL) are growth regulating signal components in plants; however, regarding their possible interplay our knowledge is limited.

S-nitrosylation of SlAPX Is Involved in Alleviating Oxidative Damage in Transgenic Tobacco under Nitrate Stress

Agronomy, 2023
Nitric oxide (NO) modulates plant response by post-translationally modifying proteins, mainly through S-nitrosylation. Ascorbate peroxidase (APX) in the ascorbate-glutathione (AsA-GSH) cycle participates in the removal of hydrogen peroxide (H2O2 ...

Exogenous application of nitric oxide donors regulates short-term flooding stress in soybean [PDF]

PeerJ, 2019
Short-term water submergence to soybean (Glycine max L.) create hypoxic conditions hindering plant growth and productivity. Nitric oxide (NO) is considered a stress-signalling and stress-evading molecule, however, little is known about its role during ...

GSNOR deficiency promotes tumor growth via FAK1 S-nitrosylation

Cell Reports, 2023
Summary: Nitric oxide (NO) production in the tumor microenvironment is a common element in cancer. S-nitrosylation, the post-translational modification of cysteines by NO, is emerging as a key transduction mechanism sustaining tumorigenesis.
