Abstract
This study identifies *SIET4*, a silicon transporter gene crucial for rice growth. *SIET4* is constitutively expressed in leaves and facilitates Si export from leaf cells to the surface. Knockout of *SIET4* leads to rice death in the presence of Si due to abnormal Si deposition in mesophyll cells and the induction of stress response genes.
