Function
Silicon influx transporter responsible for silicon transport from the external solution to the root cells . Is coupled with the silicon efflux transporter LSI2 in both exodermal and endodermal root cells for an efficient silicon transport across the cells into the stele . 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 . Is coupled with LSI2 transporter in roots for efficient uptake of arsenite; which is further dispatched in shoots and grains . Mediates uptake of methylated arsenic species in roots .

Location
Mainly expressed in the roots. In roots; it localizes in the main and lateral roots; but not in root hairs. Within a root; it localizes on the plasma membrane of the distal side of both exodermis and endodermis; where casparian strips exist (at protein level). Within a root; it localizes on the plasma membrane of the distal side of both exodermis and endodermis; where casparian strips exist (at protein level). Within a root; it localizes on the plasma membrane of the distal side of both exodermis and endodermis; where casparian strips exist (at protein level). Expressed low levels in leaves and anthers
