e0“when functional CsLsi2 from cucumber was expressed in tomato, the Si uptake was significantly increased, resulting in higher Si accumulation in the leaves and enhanced tolerance of the leaves to water deficit and high temperature.”

Other claims from this paper (9)
- Observation SlLsi1 transported silicon in rice mutants and Xenopus oocytes.
- Observation SlLsi1 was constitutively expressed in tomato roots.
- Observation SlLsi1 localized to the plasma membrane of root tips and basal regions without polarity.
- Intervention effect SlLsi1 overexpression raised silicon concentration in tomato roots and root cell sap.
- Intervention effect SlLsi1 overexpression did not alter silicon concentration in tomato shoots.
- Observation Two Lsi2-like proteins showed no silicon efflux activity in Xenopus oocytes.
- Intervention effect Expressing cucumber CsLsi2 in tomato significantly increased silicon uptake.
- Intervention effect Expressing CsLsi2 increased silicon accumulation in tomato leaves.
- Mechanism The authors attribute low tomato silicon accumulation to the lack of a functional Lsi2 efflux transporter.
