TLDR
In this article, the roles of silicon in enhancing tolerance to excess zinc (Zn) in two contrasting rice (Oryza sativa L.) cultivars were examined in rice plants grown in the nutrient solutions with normal (0.15μm) and high (2 mM) Zn supply, without or with 1.5 mM Si.Citations

Mechanisms of silicon-mediated alleviation of heavy metal toxicity in plants: A review
Muhammad Adrees,Shafaqat Ali,Muhammad Rizwan,Muhammad Zia-ur-Rehman,Muhammad Ibrahim,Farhat Abbas,Mujahid Farid,Muhammad Farooq Qayyum,Muhammad Irshad +8 more
TL;DR: The mechanisms through which Si can alleviate heavy metal toxicity in plants are reviewed and the key mechanisms evoked include reducing active heavy metal ions in growth media, reduced metal uptake and root-to-shoot translocation, chelation and stimulation of antioxidant systems in plants.

Effect of silicon on wheat seedlings (Triticum turgidum L.) grown in hydroponics and exposed to 0 to 30 µM Cu
Catherine Keller,Muhammad Rizwan,Muhammad Rizwan,J. C. Davidian,Oleg S. Pokrovsky,Oleg S. Pokrovsky,Nicolas Bovet,Perrine Chaurand,Jean-Dominique Meunier +8 more
TL;DR: Evidence is provided for Si-mediated alleviation of Cu toxicity in durum wheat and that Si supplementation to plants exposed to increasing levels of Cu in solution induces non-simultaneous changes in physiological parameters.
Journal ArticleDOI
Foliar application with nano-silicon alleviates Cd toxicity in rice seedlings
TL;DR: The results suggested that nano-Si application alleviated Cd toxicity in rice by decreasing Cd accumulation, Cd partitioning in shoot and MDA level and by increasing content of some mineral elements (Mg, Fe, and Zn) and antioxidant capacity.
Journal ArticleDOI
Silicon alleviates Cd stress of wheat seedlings (Triticum turgidum L. cv. Claudio) grown in hydroponics
Muhammad Rizwan,Muhammad Rizwan,Jean-Dominique Meunier,J. C. Davidian,Oleg S. Pokrovsky,Nicolas Bovet,Catherine Keller +6 more
TL;DR: Data strongly suggest the existence of a root localised protection mechanism consisting in armoring the root surface by Si- and Cd-bearing compounds and in limiting root–shoot translocation in durum wheat.
Journal ArticleDOI
Silicon, the silver bullet for mitigating biotic and abiotic stress, and improving grain quality, in rice?
Caroline Meharg,Andrew A. Meharg +1 more
TL;DR: A review on silicon dynamics in rice considers recent advances in the understanding of the role of silicon in rice, and the challenges of maintaining adequate silicon fertility within rice paddy systems.

Oxidative stress, antioxidants and stress tolerance
TL;DR: Key steps of the signal transduction pathway that senses ROIs in plants have been identified and raise several intriguing questions about the relationships between ROI signaling, ROI stress and the production and scavenging ofROIs in the different cellular compartments.
