Description | Lsi1 encodes a silicon transporter in rice. The sequence is similar to aquaporins and belongs to a Nod26-like major intrinsic protein (MIP) subfamily. It is consititutively expressed in the roots. Suppression of Lsi1 expression resulted in reduced silicon uptake and susceptible to pets and diseases. The grain yield is also greatly reduced in the Lsi1 mutant. |
