Phytotoxicity induced by perfluorooctanoic acid and perfluorooctane sulfonate via metabolomics
Pengyang Li,Xihui Oyang,Xiaocan Xie,Zhifang Li,Hongju Yang,Jialin Xi,Yang Guo,Xiujun Tian,Bin Liu,Jiuyi Li,Zhiyong Xiao +10 more
TL;DR: The main defense processes against PFASs exposure in lettuce included alteration in plasma membrane, activation of antioxidant systems, increase of tolerance and repair of DNA injury, and changes of antioxidants and 8-hydroxy-deoxyguanosine indicated the occurrence of oxidative stress and DNA damage under PFOA or PFOS exposure.

Amelioration of cold-induced oxidative stress by exogenous 24-Epibrassinolide treatment in grapevine seedlings: toward regulating the ascorbate-glutathione cycle.
TL;DR: In this paper, the role of brassinolide in AsA-GSH cycle in grape under chilling stress was investigated in a wine grape cultivar, Cabernet Sauvignon (Vitis vinifera), for different time points after treated by 24-Epibrassinolide (EBR).

Glutathione Metabolism in Plants under Stress: Beyond Reactive Oxygen Species Detoxification
TL;DR: In this article, the authors examined the structure and the stress regulation of the pathways involved in glutathione synthesis and degradation and provided a synthesis of the current knowledge on the Glutathione-dependent glyoxalase pathway responsible for MG detoxification.

Metabolomics Response for Drought Stress Tolerance in Chinese Wheat Genotypes (Triticum aestivum)
Xiaoyang Guo,Zeyu Xin,Tiegang Yang,Xingli Ma,Yang Zhang,Zhiqiang Wang,Yongzhe Ren,Tongbao Lin +7 more
TL;DR: The understanding of the mechanisms involved in the drought response of wheat seedling is explored and these metabolome data could also be used for potential QTL or GWAS studies to identify locus (loci) or gene(s) associated with these metabolic traits for the crop improvement.

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.
