Abstract

How rice grabs its silicon Silicon plays a beneficial role in plant growth: it increases the resistance of plants to pests and diseases and helps minimize transpiration losses. Rice is a typical silicon-accumulating plant, able to build up silicon levels in the shoots thanks to the ability of the roots to take it up from the soil. The sophisticated system that achieves this was partially characterized when a 'low silicon' gene, Lsi1, was shown to encode an influx transporter to move silicon from the soil into root cells. Now, the second step in the process — the efflux of silicon from root cells into the core of vascular tissue running through the root — has been revealed with the discovery of a second low silicon gene, the efflux transporter Lsi2.
