The effects of salicylic acid (SA) pretreatment on ascorbate–glutathione (GSH) cycle under chilling stress in eggplant seedlings were investigated. Salicylic acid pretreatment improved chilling resistance of eggplant seedlings with maximum efficiency at a concentration of 0.3%. The chilling injury index was decreased by 36.9% as compared to that of the control after 0.3% SA pretreatment. Under chilling stress, seedlings pretreated with SA displayed lower hydrogen peroxide (H2O2) content and… Expand

Exogenous salicylic acid enhances wheat drought tolerance by influence on the expression of genes related to ascorbate-glutathione cycle
Treatment with 0.5 mM salicylic acid (SA) significantly alleviated growth inhibition induced by drought in wheat seedlings, manifested by less decreassed fresh mass, dry mass, plant height, rootExpand
Salicylic acid increases the contents of glutathione and ascorbate and temporally regulates the related gene expression in salt-stressed wheat seedlings.
TLDR
The results implied that SA temporally regulated the transcript levels of the genes encoding ASA-GSH cycle enzymes, resulting in the increased contents of GSH and ASA and enhanced salt tolerance. Expand
Abscisic acid enhances tolerance of wheat seedlings to drought and regulates transcript levels of genes encoding ascorbate-glutathione biosynthesis
TLDR
Exogenous application of ABA significantly increased the tolerance of seedlings of common wheat suffering from 5 days of 15% polyethylene glycol (PEG)-stimulated drought stress, as demonstrated by increased shoot lengths and shoot and root dry weights, while showing decreased content of hydrogen peroxide (H2O2) and malondialdehyde (MDA).

Exogenous 24-epibrassinolide alleviates zinc-induced toxicity in eggplant (Solanum melongena L.) seedlings by regulating the glutathione-ascorbate-dependent detoxification pathway
TLDR
The results of the present study suggest that exogenous EBL confers resistance against Zn-induced oxidative damage by enhancing the ASA-GSH cycle by up-regulating key gene expression and key enzyme activities. Expand

Abscisic acid enhances tolerance to spring freeze stress and regulates the expression of ascorbate–glutathione biosynthesis-related genes and stress-responsive genes in common wheat
TLDR
The present study showed that exogenous abscisic acid pre-treatment remarkably increases the freeze tolerance of common wheat seedlings at the anther connective tissue formation phase (ACFP) and tetrad developmental phase and suggested that plant hormones induce an increase in GSH and ASA levels, possibly by differentially regulating the expression levels of genes encoding ASA–GSH synthesis enzymes.

Exogenous 6-benzylaminopurine confers tolerance to low temperature by amelioration of oxidative damage in eggplant (Solanum melongena L.) seedlings
TLDR
It can be concluded that 6-BA can play a positive role in the alleviation of oxidative damage caused by ROS overproduction through enhancing antioxidant defense system, resulting in improving the low-temperature tolerance. Expand

Epibrassinolide confers zinc stress tolerance by regulating antioxidant enzyme responses, osmolytes, and hormonal balance in Solanum melongena seedlings
TLDR
Evaluating the role of exogenous epibrassinolide in some physiological processes in the leaves of eggplant seedlings grown under zinc (Zn) stress conditions revealed that EBL greatly alleviated harmful effects of Zn stress on eggplants by activating antioxidant enzyme responses, accumulation of osmolytes, and balancing endogenous hormones. Expand
Modulation of zinc-induced oxidative damage in Solanum melongena by 6-benzylaminopurine involves ascorbate–glutathione cycle metabolism
TLDR
The results of the present study strongly suggest that BAP-enhanced resistance of eggplants against Zn toxicity is associated with the regulation of AsA–GSH cycle metabolism as an effective antioxidant system and the balance of hormones. Expand
