Possible Interaction: Aminolevulinic Acid and Antioxidants

“ Antioxidant status was impaired after the Fe period, as indicated by decreased FRAP (P < 0.005) and delta-ALAD activity (P < 0.05) and increased EOF (P < 0.01).”

“Application of ALA at 25mg/l dosage significantly enhanced the antioxidant activities e.g. APX, SOD, POD, and GSH contents under Cd stress.”

“administration of ALA could be affected by antioxidants.”

“Chronic administration of delta-aminolevulinic acid (2 weeks) markedly decreased activities of the porphyrogenic enzymes delta-aminolevulinate synthase (ALA-S) and delta-aminolevulinate dehydratase (ALA-D) and of the antioxidant enzymes superoxide dismutase (SOD), glutathione reductase (GR) and catalase (CAT), whereas porphobilinogen deaminase (PBG-D) remained unaffected.”

“ ALA enhances abiotic stress tolerance as well as growth and yield by regulating photosynthetic and antioxidant machineries and nutrient uptake in plants.”

“Silencing of GSTU43 with virus-induced gene silencing reduced the activities of GST, superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase, and increased the membrane lipid peroxidation; while fed with ALA significant increased all these antioxidase activities and antioxidant contents, and alleviated the membrane damage.”

“Our results suggest the up-regulation of antioxidant enzyme activities, nutrient contents, and hormone accumulation with the application of ALA increases tolerance to low-temperature stress, leading to improved cucumber seedling performance.”

“Priming Slaski 2 and Carmen cultivars with ALA under salt stress significantly induced pigment contents, antioxidants enzymes activity and stress-responsive genes expression, relative to NaCl-stressed plants.”

“Foliar application ALA decreased the levels of MDA, EL, and H2O2 while further improved the performance of antioxidant in both leaves and roots compared to only Cr-stressed plant.”

“Further analyses showed that ALA and NO enhanced antioxidant defense and activated plasma membrane (PM) H+-ATPase and decreased the accumulation of ROS induced by chilling stress.”
