Intervention effect Reduced glutathione retarded PEG-induced oxidative damage in detached rice leaves.
Intervention effect Thiourea retarded PEG-induced oxidative damage in detached rice leaves.
Intervention effect 2,2'-bipyridine (BP) prevented PEG-induced oxidative damage in detached rice leaves.
Intervention effect 8-hydroxyquinoline prevented PEG-induced oxidative damage in detached rice leaves.
Intervention effect 1,10-phenanthroline prevented PEG-induced oxidative damage in detached rice leaves.
Intervention effect Adding Fe2+ and Cu2+ reversed the protective effect of BP in PEG-treated rice leaves.
Intervention effect Adding Mn2+ or Zn2+ did not reverse the protective effect of BP in PEG-treated rice leaves.
Mechanism The protective effect of BP is most likely mediated through chelation of iron.
Mechanism Oxidative damage induced by PEG may require the participation of iron.

Differential Impact of Nitric Oxide and Abscisic Acid on the Cellular and Physiological Functioning of sub1A QTL Bearing Rice Genotype under Salt Stress

Indraneel Saha; Arijit Ghosh; Debabrata Dolui; et al. Plants 2022. doi:10.3390/plants11081084

Other claims from this paper (11)

Intervention effect Exogenous SNP and ABA sensitized cv. Swarna Sub1 more than cv. Swarna, with different cellular responses.
Intervention effect Salinity lowered relative water content and osmotic potential irrespective of cultivar.
Intervention effect Salinity decreased the compatible solutes alanine, gamma-aminobutyric acid and glycine betaine.
Intervention effect Salinity was accompanied by a decrease in photosynthetic reserves.
Intervention effect NaCl stress gradually declined NADP-malic enzyme activity, sucrose accumulation and ascorbate peroxidase.
Intervention effect NaCl stress gradually declined glutathione S-transferase activity.
Intervention effect Salinity also declined invertase activity (wall and cytosolic forms).
Intervention effect Salinity increased superoxide, hydrogen peroxide and their biosynthetic enzymes such as NADP(H) oxidase, causing oxidative stress.
Association Moderation of Na+/K+ by SNP and ABA was correlated with other salt sensitivities in the plants.
Intervention effect SNP and ABA had their maximum effects on recovery of antioxidation pathways, osmotic tolerance and carbohydrate metabolism.
Intervention effect SNP and ABA, alone or together, are predicted to overcome NaCl toxicity in rice.
