TL;DR: It was found that Candida tropicalis prevented phenol-caused cell damage through improvement of cell wall resistance, maintenance of high-fidelity DNA replication, intracellular protein homeostasis, organelle integrity, and kept the intrace cellular phenol concentration at a low level through cell-wall remodeling and removal of excess phenol via MDR/MXR transporters.

Gamma-aminobutyric acid improves phenanthrene phytotoxicity tolerance in cucumber through the glutathione-dependent system of antioxidant defense.
TL;DR: In this paper, the role and regulatory mechanisms of gamma-aminobutyric acid (GABA) in PHE stress responses in plants remains largely uncharacterized, however, it has been shown that GABA content increased by 44.5%, 89.2%, 160% and 39.2% under 50, 100, 200 and 300 µM PHE treatment, respectively compared with mock.

Transcriptomic profiling and identification of candidate genes in two Phoebe bournei ecotypes with contrasting cold stress responses
TL;DR: The stronger transcriptional differentiation of related genes under cold stress in WY may explain its greater cold resistance compared with the WP ecotype, providing important genetic resources for improving cold-resistant characteristics in P. bournei.

Defense Induced by Jasmonic Acid: A Review
TL;DR: In this paper, it has been shown that plant defense responses are mediated by three major pathways of the phytohormones, jasmonic acid (JA), salicylic acid (SA), and ethylene (ET), and fine tuning of plant response to pathogen depends on synergistic or antagonistic interactions between these three pathways.
Book ChapterDOI
Protein Denitrosylation in Plant Biology
TL;DR: This analysis has revealed that a wide range of both physiological and stress response processes are regulated by this post-translational modification, and denitrosylation, the removal of an NO group from an SNO, has emerged as a key regulatory process.

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.

TL;DR: How alterations in glutathione status, such as those observed during stress, may participate in signal transduction cascades are discussed and how these alterations are integrated to fine-tune photorespiratory and respiratory metabolism and to modulate phytohormone signalling pathways.
Journal ArticleDOI
Biotechnological approach of improving plant salt tolerance using antioxidants as markers.
TL;DR: The role of different antioxidants as potential selection criteria for improving plant salt tolerance has been critically discussed and the potential of this approach in counteracting stress-induced oxidative stress has been discussed at length in this review.
