Pre-soaking in Weed Extracts is a Reasonable Approach to Mitigate Fusarium graminearum Infection in Wheat
Sherien Sobhy,Essam-Eldeen M. Abo-Kassem,Nasser Sewelam,Elsayed E. Hafez,Dalia G. Aseel,Khalil M. Saad-Allah +5 more
TL;DR: Natural weed extracts as supplement to chemical antifungals can be safely employed to increase the growth rate and reconfigure the pathophysiological status of wheat seedlings by reducing the detrimental effects of F. graminearum infection.

Oxidative stress status, antioxidant metabolism and polypeptide patterns in Juncus maritimus shoots exhibiting differential mercury burdens in Ria de Aveiro coastal lagoon (Portugal)
TL;DR: Significantly elevated activity of non-glutathione-based H2O2-metabolizing enzymes such as ascorbate peroxidase and catalase accompanied the studied damage-endpoint responses, whereas the activity of glutathione -based H1N1-scavenging enzyme system was inhibited and the contents of both reduced and oxidized glutATHione were perceptible in high mercury-exhibiting shoots.

Oxidant and antioxidant signalling in plants: a re-evaluation of the concept of oxidative stress in a physiological context
Christine H. Foyer,Graham Noctor +1 more
TL;DR: It is proposed that the oxidative stress syndrome would be more usefully described as 'oxidative signalling', that is, an important and critical function associated with the mechanisms by which plant cells sense the environment and make appropriate adjustments to gene expression, metabolism and physiology.
