Silicon, the silver bullet for mitigating biotic and abiotic stress, and improving grain quality, in rice? (2015, background): “Rice has specific mechanisms for assimilating silicon from soil as soluble silicic acid, and for unloading silicic acid into the xylem, through the aquaglyceroporins lsi1 and lsi2 (i.e. Ma et al., 2006, 2007a).”
Regulation and function of root exudates. (2008, background): “Recent evidence demonstrated that the silicon efflux transporter from rice is involved in efflux of silicon from root cells (Ma et al. 2007; Ma & Yamaji 2008).”
Rice is more efficient in arsenite uptake and translocation than wheat and barley (2010, background): “Variation in Si uptake among rice or barley cultivars was found to correlate with the expression level of Lsi1 in roots (Chiba et al. 2009; Ma et al. 2007b).”
Transporters of arsenite in rice and their role in arsenic accumulation in rice grain (2008, background): “To investigate whether Lsi2 can transport arsenite, we compared As accumulation between the wild-type rice and a mutant (lsi2) defective in silicic acid transport (32).”
Linking transport system of silicon with its accumulation in different plant species (2020, background): “Knockout of either OsLsi1 or OsLsi2 results in a significant decrease of Si uptake by the roots, indicating that both of them are required for high Si uptake (Tamai and Ma 2003; Ma et al. 2006, 2007).”
Arsenic uptake and metabolism in plants. (2009, background): “Tansley review © The Authors (2008) New Phytologist (2009) 181: 777–794 Journal compilation © New Phytologist (2008) www.newphytologist.org Review 781 As accumulation in rice, the efflux of arsenite toward xylem mediated by Lsi2 is the crucial step in controlling As accumulation in rice shoots and g”
The roles of membrane transporters in arsenic uptake, translocation and detoxification in plants (2020, background): “In rice, the silicon efflux transporter OsLsi2 that is localized at the proximal side of both exodermal and endodermal cells of the roots, plays an important role in the radial transport of As(III) toward the stele for xylem loading (Ma et al., 2007; 2008).”
Toxic Heavy Metal and Metalloid Accumulation in Crop Plants and Foods. (2016, background): “It belongs to a family of anion transporters and effluxes silicic acid from the cytosol at the proximal side of exodermis and endodermis cells (71).”
Nramp5 Is a Major Transporter Responsible for Manganese and Cadmium Uptake in Rice[C][W] (2012, background): “In the case of Si, an efflux transporter, Lsi2, localized at the proximal side of the same cell layers is required for releasing Si from the cells toward the stele (Ma et al., 2007).”
Arsenic Toxicity: The Effects on Plant Metabolism (2012, background): “The localization of OsLsi2 to the proximal side of epidermal and endodermal cells (Ma et al., 2007), and OsLsi1 to the distal side of the same cells (Ma et al.”
