Abstract
Two different types of silicon (Si) transporter, influx and efflux, are involved in the Si-transport process of higher plants. The transporters responsible for Si uptake by roots (Lsi1 and Lsi2) have been identified in several higher plant species including rice (Oryza sativa), barley (Hordeum vulgare), maize (Zea mays), wheat (Triticum aestivum), pumpkin (Cucurbita moschata) and the primitive vascular plant, Equisetum arvense (horsetail). An influx transporter, Lsi6, involved in xylem unloading of Si has also been identified in graminaceous species, including rice, barley and corn. In this chapter, an overview will be provided to highlight the most recent breakthroughs in Si uptake and transport by plants.
