Isolation and functional characterization of CsLsi2, a cucumber silicon efflux transporter gene

Abstract

The results suggest that CsLsi2 is a silicon efflux transporter gene in cucumber. The coordination of CsLsi1 and CsLsi2 mediates silicon uptake in cucumber roots. This study may help us understand the molecular mechanism for silicon uptake in cucumber, one of the few dicots with a relatively high capacity for silicon accumulation.
