Silicon (Si) Uptake

  • Gyanendra Nath Mitra


Silicon (Si) is the second most abundant element after oxygen and constitutes 27.7 % of the earth’s crust. While the occurrence of pure silicon is rare, silicate minerals account for 90 % of the mass of the earth’s crust. Silicon is a constituent of all plants, and its concentration in shoot may vary from 0.1 to 10 % of dry weight. Plants take up Si primarily as orthosilicic acid. LSi1 (low silicon 1) is a member of NIP2 subgroup of NIP subfamily of aquaporin-like proteins and functions as a Si-permeable channel. LSi6 is a homologue of LSi1 and is involved in xylem unloading of Si in rice.
