Silicon accumulation in shoots suppresses cobalt uptake in rice through cobalt transporter gene downregulation.

Abstract excerpt

Cobalt (Co) enrichment in agricultural soils presents growing concerns for food security and human well-being. Although silicon (Si) is known to mitigate the toxicity of several heavy metals in plants, its specific role in regulating Co behavior in rice remains insufficiently characterized. Here, Si-Co interactions were examined with a silicon-deficient rice mutant (lsi1) alongside its wild-type (WT) control....
