High Silicon Accumulation in the Shoot is Required for Down-Regulating the Expression of Si Transporter Genes in Rice

In conclusion, the Si-induced down-regulation of Si transporter genes is controlled by shoot Si, not root Si, and the region between –327 and –292 in the OsLsi1 promoter is involved in this regulation of OsLsi1 expression in rice.
