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.

Abstract: Silicon is beneficial to plant growth and helps plants to overcome abiotic and biotic stresses by preventing lodging (falling over) and increasing resistance to pests and diseases, as well as other stresses. Silicon is essential for high and sustainable production of rice, but the molecular mechanism responsible for the uptake of silicon is unknown. Here we describe the Low silicon rice 1 (Lsi1) gene, which controls silicon accumulation in rice, a typical silicon-accumulating plant. This gene belongs to the aquaporin family and is constitutively expressed in the roots. Lsi1 is localized on the plasma membrane of the distal side of both exodermis and endodermis cells, where casparian strips are located. Suppression of Lsi1 expression resulted in reduced silicon uptake. Furthermore, expression of Lsi1 in Xenopus oocytes showed transport activity for silicon only. 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.

Management of rice blast with different fungicides and potassium silicate under in vitro and in vivo conditions
R. Raj,P.P.S. Pannu +1 more
TL;DR: The potassium silicate applied at 40 and 50 ml/l was found effective against rice blast and significantly increased the grain yield by reducing the toppling of panicles and can provide us with an environmentally safe alternative source to rice blast disease management.

Mutiara K. Pitaloka,Emily L. Harrison,Christopher Hepworth,Samart Wanchana,Theerayut Toojinda,Watchara Phetluan,Robert A Brench,Supatthra Narawatthana,Apichart Vanavichit,Julie E. Gray,Robert S. Caine,Siwaret Arikit +11 more
TL;DR: In this article, an anatomical screen of 64 Thai and 100 global rice cultivars was undertaken to identify agronomic traits related to rice stomatal complexes, and the potential function(s) of mega-papillae were studied by assessing gas exchange and pathogen infection rates.

Efficient transformation of rice (Oryza sativa L.) mediated by Agrobacterium and sequence analysis of the boundaries of the T-DNA.
TL;DR: A large number of morphologically normal, fertile, transgenic rice plants were obtained by co-cultivation of rice tissues with Agrobacterium tumefaciens, and sequence analysis revealed that the boundaries of the T-DNA in transgenic Rice plants were essentially identical to those intransgenic dicotyledons.

The anomaly of silicon in plant biology.
TL;DR: Ample evidence is presented that silicon, when readily available to plants, plays a large role in their growth, mineral nutrition, mechanical strength, and resistance to fungal diseases, herbivory, and adverse chemical conditions of the medium.

Silicon and plant disease resistance against pathogenic fungi
TL;DR: Silicon possesses unique biochemical properties that may explain its bioactivity as a regulator of plant defense mechanisms, and may interact with several key components of plant stress signaling systems leading to induced resistance.
