The Role of Ascorbate–Glutathione System and Volatiles Emitted by Insect-Damaged Lettuce Roots as Navigation Signals for Insect and Slug Parasitic Nematodes [PDF]

open access: yesInsects, 2023
The effect of wireworm-damaged lettuce roots on the antioxidative defense system (ascorbate–glutathione cycle, photosynthetic pigments) and movement of insect/slug parasitic nematodes towards determined root exudates was studied in a glasshouse ...

Synergistic modulation of antioxidant enzymes by citric acid and EDTA to enhance lead tolerance and phytoextraction efficiency in harmel [PDF]

open access: yesScientific Reports
Lead (Pb) induces physiological, morphological, and metabolic effects in plants. The exogenous application of ethylenediaminetetraacetic acid (EDTA) and citric acid (CA) is a common method to enhance the phytoextraction of Pb from plants.

Expression of Heterologous OsDHAR Gene Improves Glutathione (GSH)-Dependent Antioxidant System and Maintenance of Cellular Redox Status in Synechococcus elongatus PCC 7942. [PDF]

open access: yes, 2020
An excess of reactive oxygen species (ROS) can cause severe oxidative damage to cellular components in photosynthetic cells. Antioxidant systems, such as the glutathione (GSH) pools, regulate redox status in cells to guard against such damage ...
