Silica nanoparticles alleviate cadmium toxicity to <i>Pisum sativum</i> L. seedling growth by remodeling carbon-nitrogen metabolism.

Under Cd stress, the Cd+nSiO 2 interaction treatment promoted the accumulation of Cu, Mg and Zn in pea seedlings ( Supplementary Figures S2C–E ), but this difference did not reach statistical significance. 3.7 Transcriptome analysis To explore the molecular mechanism underlying the alleviation of Cd toxicity to pea seedlings by nSiO 2 and elucidate the potential regulatory pathway of the nSiO 2 -mediated response to Cd stress in pea, we performed transcriptome sequencing analysis on pea seedlings exposed to Cd toxicity, nSiO 2 treatment, or Cd+nSiO 2 interactive treatment.
