Mechanisms involved in the boosting effects of the alternating current electric field on cadmium enrichment of Sedum alfredii Hance.
PubMed · 2026-05-30
Scientists used gentle alternating electrical current in water to dramatically boost a plant's ability to pull toxic cadmium out of contaminated soil, revealing the genetic and hormonal mechanisms that make it work.
1
Alternating current significantly increased both biomass yield and cadmium accumulation in Sedum alfredii compared to controls.
2
AC exposure upregulated most genes encoding metal transport and detoxification proteins (IRT, ZIP, NRAMP, HMA, MTs, PCs), driving more cadmium into shoot tissues.
3
Mantel analysis and structural equation modeling showed that gene expression upregulation — not just physical ion movement — was the primary driver of enhanced cadmium enrichment.
