Fresh-cut pumpkin is favored by consumers for its environmental protection, safety, and convenience at home abroad. To investigate the effect of different wounding intensities (piece, strip slice, corresponding to 1.90, 3.53 6.29 m2 kg−1) on quality fresh-cut pumpkin, critical indexes involved in reactive oxygen species (ROS) metabolism, vitamin C-glutathione cycle, phenylpropanoid metabolism m...

Ketogulonicigenium vulgare, though grows poorly when mono-cultured, has been widely used in the industrial production of the precursor of vitamin C with the coculture of Bacillus megaterium. Various efforts have been made to clarify the synergic pattern of this artificial microbial community and to improve the growth and production ability of K. vulgare, but there is still no sound explanation....

The purpose of the current study was to determine possible improvement in soybean plants’ tolerance against vanadium-induced stress response application olive solid waste (OSW) and selenium nanoparticles (Se-NPs), by assessing metabolites plant defense systems. Drawing upon this aim, a pot experiment performed where plants were grown with fertilization treatment (including, control, OSW, Se-NPs...

Abstract The protective mechanism of nitric oxide (NO) in regulating tolerance to Cu-induced toxicity shoots barley ( Hordeum vulgare L.) was studied. experiment consisted four treatments based on additions basal nutrient solutions (BNS): control (CTR), Cu (200 µM), SNP (500 and µM) + over a period 10 days. Treatment with significantly reduced seedling growth photosynthetic efficiency concomita...

T. Chan, V-A. Raymond, M. Bilodeau, D. Leibfritz, C. Zwingmann Centre de Recherche, Hospital Saint-Luc, Montreal, Quebec, Canada, Department of Organic Chemistry, University of Bremen, Bremen, Bremen, Germany Introduction. Acetaminophen (AAP) is converted by the cytochrome P450 pathway to a toxic intermediate, N-acetyl-p-benzoquinone-imine (NAPQI), which is usually completely detoxified through...

Reduced forms of ascorbate (AsA) and glutathione (GSH) are among the most important non-enzymatic foliar antioxidants in maize (Zea mays L.). The survey was aimed to evaluate impact of bird cherry-oat aphid (Rhopalosiphum padi L.) or grain aphid (Sitobion avenae F.) herbivory on expression of genes related to ascorbate-glutathione (AsA-GSH) cycle in seedlings of six maize varieties (Ambrozja, N...

The effect o f paraq u a t on hydroxyl radical production , glutathione and ascorbate content, and glutathione reductase and superoxide dism utase activities was assayed in the to lerant “K w angkyo” and the susceptible “ H o o d ” cultivars o f soybean [Glycine max (L.) Merr.]. Seed­ lings o f both cultivars a t the fully expanded first trifoliate leaf stage were treated with paraquat at 0, 1,...

Abiotic stress poses major problems to agriculture and increasing efforts are being made to understand plant stress response and tolerance mechanisms and to develop new tools that underpin successful agriculture. However, the molecular mechanisms of plant stress tolerance are not fully understood, and the data available is incomplete and sometimes contradictory. Here, we review the significance...

background: glutathione (gsh) is a non-protein thiol compound, which plays an important role in the response to oxidative stress and nutritional stress. the aim of this study was to isolate indigenous s. cerevisiae strains capable of effectively produce gsh. methods: one hundred-twenty sweet fruit samples were collected. the strains were isolated on yeast glucose chloramphenicol (ygc) agar medi...
