Arsenic uptake and metabolism in plants.
TL;DR: Hyperaccumulation appears to involve enhanced arsenate uptake, decreased arsenite-thiol complexation and arsenite efflux to the external medium, greatly enhanced xylem translocation of arsenite, and vacuolar sequestration of arsenites in fronds.

An efflux transporter of silicon in rice
Jian Feng Ma,Naoki Yamaji,Namiki Mitani,Kazunori Tamai,Saeko Konishi,Toru Fujiwara,Maki Katsuhara,Masahiro Yano +7 more
TL;DR: A previously uncharacterized gene is described, low silicon rice 2 (Lsi2), which has no similarity to Lsi1 and is constitutively expressed in the roots and revealed a unique mechanism of nutrient transport in plants: having an influx transporter on one side and an efflux transporter on the other side of the cell to permit the effective transcellular transport of the nutrients.

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.

A silicon transporter in rice
Jian Feng Ma,Kazunori Tamai,Naoki Yamaji,Namiki Mitani,Saeko Konishi,Maki Katsuhara,Masaji Ishiguro,Yoshiko Murata,Masahiro Yano +8 more
TL;DR: 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.
Journal ArticleDOI
Role of silicon in enhancing the resistance of plants to biotic and abiotic stresses
TL;DR: The role of Si in conferring resistance to mutiple stresses is described and genetic modification of the root ability to take up Si has been proposed to obtain plants resistant to multiple stresses.
Journal ArticleDOI
Phylogenetic Variation in the Silicon Composition of Plants
TL;DR: Information on the phylogenetic variation in shoot Si concentration may provide useful palaeoecological and archaeological information, and inform studies of the biogeochemical cycling of Si and those of the molecular genetics of Si uptake and transport in plants.

Silicon alleviates salt stress and increases antioxidant enzymes activity in leaves of salt-stressed cucumber (Cucumis sativus L.)
TL;DR: Higher activities of SOD, GPX, APX, DHAR and GR in salt-stressed leaves induced by Si addition may protect the plant tissues from membrane oxidative damage under salt stress, thus mitigating salt toxicity and improving the growth of cucumber plants.

Silicon alleviates oxidative damage of wheat plants in pots under drought
TL;DR: It was suggested that the improvement of silicon on drought tolerance of wheat plants was associated with the increase of antioxidant defense abilities, therefore alleviating oxidative damage of cellular functional molecules induced by over produced reactive oxygen species (ROS) under drought and maintaining many physiological processes of stressed plants.
