A positive role for EBR is advocated in reducing pollutant residues for food safety and also strengthening phytoremediation as a result of a potential interaction of EBR and PHE for Cd stress alleviation. Expand
Melatonin mitigates cadmium phytotoxicity through modulation of phytochelatins biosynthesis, vacuolar sequestration, and antioxidant potential in Solanum lycopersicum L
It is shown that optimal dose of melatonin could effectively ameliorate Cd-induced phytotoxicity in tomato and suggest that melatonin-induced enhancements in antioxidant potential, phytochelatins biosynthesis and subsequent Cd sequestration might play a critical role in plant tolerance to Cd. Expand
Brassinosteroid alleviates phenanthrene and pyrene phytotoxicity by increasing detoxification activity and photosynthesis in tomato.
The results suggest that BR has an anti-stress effect on tomato seedlings contaminated with PHE or PYR and this effect is mainly attributed by increased detoxification activity. Expand

Investigation of biomass, photosynthetic machinery and antioxidant system in pakchoi, cucumber, flowering chinese cabbage, tomato and lettuce under various levels of phenanthrene (PHE) stress found difference in defense capacity might result in different tolerance and phytotoxicity among the studied vegetables.

Results showed that increases in DWF transcripts and endogenous BR level resulted in improved germination, lateral root development, CO2 assimilation and eventually plant growth as characterized by slender and compact plant architecture. Expand
Grafting cucumber onto luffa improves drought tolerance by increasing ABA biosynthesis and sensitivity
It is demonstrated that the roots of luffa have developed an enhanced ability to sense the changes in root-zone moisture and could eventually deliver modest level of ABA from roots to shoots that enhances water use efficiency under drought stress. Expand

This review provides a broad overview of recent advances in cellular protein research with regards to heavy metal tolerance in plants and discusses how plants maintain functional and healthy proteomes for survival under such capricious surroundings. Expand
Brassinosteroid alleviates polychlorinated biphenyls-induced oxidative stress by enhancing antioxidant enzymes activity in tomato.
The results suggest a protective role of EBR against PCBs stress which may strengthen phytoremediation approaches by enhancing plant tolerance. Expand
HsfA1a upregulates melatonin biosynthesis to confer cadmium tolerance in tomato plants
It is demonstrated that transcription factor heat‐shock factor A1a (HsfA1a) conferred cadmium (Cd) tolerance to tomato plants, in part through its positive role in inducing melatonin biosynthesis under Cd stress. Expand
Glutathione-mediated regulation of nitric oxide, S-nitrosothiol and redox homeostasis confers cadmium tolerance by inducing transcription factors and stress response genes in tomato.
It is suggested that GSH increases tomato tolerance to Cd stress not only by promoting the chelation and sequestration of Cd but also by stimulating NO, SNO and the antioxidant system through a redox-dependent mechanism. Expand
