Journal ArticleDOI
Candida albicans glutathione reductase downregulates Efg1-mediated cyclic AMP/protein kinase A pathway and leads to defective hyphal growth and virulence upon decreased cellular methylglyoxal content accompanied by activating alcohol dehydrogenase and glycolytic enzymes.
TL;DR: This is the first report that GLR1-triggered Efg1-mediated signal transduction repression strictly reduces dimorphic switching and virulence by maintaining the basal level of methylglyoxal following the enhanced gene expressions of glycolytic enzymes and ADH1.

iTRAQ-based comparative proteomic response analysis reveals regulatory pathways and divergent protein targets associated with salt-stress tolerance in kenaf (Hibiscus cannabinus L.)
Muhammad Haneef Kashif,Wei Fan,Danfeng Tang,Meiqiong Tang,Dengjie Luo,Lu Hai,Ru Li,Peng Chen +7 more
TL;DR: In this paper, a comparative cytological, physiological, and proteomic analysis was performed on a salt-sensitive (P3B) and salt-tolerant(P3A) kenaf seedlings under salt stress.

TL;DR: The genetic architecture of Cd accumulation and tolerance in Populus nigra L. nigra would be a good candidate for the phytoremediation of metal-polluted sites and some CGs are directly related to Cd transport and detoxification, whereas other non-metal-specific CGs could also contribute to explain the phenotypic variation in Cd accumulated and tolerance.

Arbuscular mycorrhizal fungi and exogenous glutathione mitigate coal fly ash (CFA)-induced phytotoxicity in CFA-contaminated soil.
TL;DR: It is demonstrated that AMF and GSH have the potential to mitigate CFA-induced phytotoxicity and could be further harnessed for efficient utilization of switchgrass plant in the phytoremediation of CFA contaminated soil environment while simultaneously limiting CFA

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.

Glutathione in plants: an integrated overview.
Graham Noctor,Amna Mhamdi,Sejir Chaouch,Yi Han,Jenny Neukermans,Belén Márquez-García,Guillaume Queval,Christine H. Foyer +7 more
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.
