Glutathione (GSH) plays a critical role in plant growth, development and responses to stress. However, the mechanism by which GSH regulates tolerance to cadmium (Cd) stress still remains unclear. Here we show that inhibition of GSH biosynthesis by buthionine sulfoximine (BSO) aggravated Cd toxicity by increasing accumulation of reactive oxygen species (ROS) and reducing contents of nitric oxide (NO) and S-nitrosothiol (SNO) in tomato roots. In contrast, exogenous GSH alleviated Cd toxicity by… Expand
Exogenous Glutathione-Mediated Abiotic Stress Tolerance in Plants
Glutathione (GSH), a major non-protein low-molecular-weight thiol tripeptide in plant cells, is involved in a variety of life processes, including cell differentiation, removal of free radicals andExpand
Glutathione-induced alleviation of cadmium toxicity in Zea mays.
TLDR
It is revealed that GSH reversed the adverse effects of Cd, as reflected by plant growth, plant hormones, vacuole, stoma development, gene expression, etc, and a promising strategy for safe food production is indicated. Expand
Nitric oxide-mediated regulation of sub-cellular chromium distribution, ascorbate-glutathione cycle and glutathione biosynthesis in tomato roots under chromium (VI) toxicity.
TLDR
NO mitigates Cr(VI) toxicity in tomato roots by reducing Cr and oxidative stress markers accumulation, triggering sequestration of Cr into vacuoles, and up-regulating ascorbate-glutathione cycle and glutathione biosynthesis, and phytochelatins. Expand

TLDR
The roles of NO in confronting HM phytotoxicity in plants are described with a particular focus on the presentation and discussion of recent data obtained in this field, which involves in the function of various phytohormones and S-nitrosylation during plant responses to HM stress. Expand
New insights into cadmium stressful-conditions: Role of ethylene on selenium-mediated antioxidant enzymes.
TLDR
Investigating the role of ethylene in Se-modulation of antioxidant defence system in response to Cd-stress suggested that ethylene may be involved in Se induced-defence responses, that triggers a positive response of the antioxidant system and improve growth under Cd stress. Expand
Exogenous glutathione enhances cadmium accumulation and alleviates its toxicity in Populus × canescens
TLDR
Exogenous GSH can enhance Cd accumulation and alleviate its toxicity in poplars, and is probably attributed to external-GSH-induced higher net Cd2+ influx in the roots, greaterCd accumulation in aerial parts, stronger scavenging of reactive oxygen species, and transcriptional overexpression of several genes involved in Cd uptake, detoxification and accumulation.

TLDR
It is highlighted that NO and Si synergistically interact to mitigate detrimental effects of As stress through reducing As uptake and combined No and Si application in As spiked soils for improvement of plant growth and stress alleviation. Expand
