Silicon (Si) has attracted substantial attention because of its beneficial effect on plants during abiotic stress, including stress due to arsenic (As). We here report that priming rice seeds with As and Si together, helped the plant to sustain As stress for longer period. We examined Si induced tolerance against As in rice seedlings at short (7 d) and long (15 d) exposure periods under As(III) and Si treatments since their germinating stage. Results showed that the expression of As(III… 
THE ROLE OF SILICON TO INCREASE ARSENIC TOLERANCE IN RICE (Oryza sativa L.) SEEDLINGS BY REINFORCING ANTI-OXIDATIVE DEFENSE
Arsenic is a toxic metalloid which can cause severe problems to plants. On the other hand, silicon is a beneficial element, which supports plants to build resistance under stressed conditions. The
Alleviation mechanisms of metal(loid) stress in plants by silicon: A review.
TLDR
This review focuses on all currently known plant-based mechanisms related to Si supply and involved in amelioration of stress caused by excess metal(loid)s.
Sulphur potentiates selenium to alleviate arsenic-induced stress by modulating oxidative stress, accumulation and thiol-ascorbate metabolism in Brassica juncea L.
TLDR
AS nutrition potentiated Se to alleviate As-inhibited plant growth by modulating antioxidants including thiol-ascorbate-based mechanism and reducing As accumulation in B. juncea plants.

Silicon mitigates heavy metal stress by regulating P-type heavy metal ATPases, Oryza sativa low silicon genes, and endogenous phytohormones
TLDR
The present study supports the active role of Si in the regulation of stresses from heavy metal exposure through changes in root morphology and shows a significant up-regulation of mRNA expression with Si treatment in rice plants.
A silicon transporter in rice
TLDR
The identification of a silicon transporter provides both an insight into the silicon uptake system in plants, and a new strategy for producing crops with high resistance to multiple stresses by genetic modification of the root's silicon uptake capacity.
High Silicon Accumulation in the Shoot is Required for Down-Regulating the Expression of Si Transporter Genes in Rice.
TLDR
The Si-induced down-regulation of Si transporter genes is controlled by shoot Si, not root Si, and the region between -327 and -292 in the OsLsi1 promoter is involved in this regulation of OsLSI1 expression in rice.
Effect of silicon on wheat seedlings (Triticum turgidum L.) grown in hydroponics and exposed to 0 to 30 µM Cu
TLDR
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.
