- •
Si restored growth and membrane stability of Cd-stressed pea plants.
- •
Expression of GSH1 and MTA transcripts strongly induced due to Si under Cd stress in roots of peas.
- •
Uptake of Fe and expression of RIT1 correlated with Cd uptake and translocation in peas.
- •
Si caused significant increase in CAT, POD, SOD and GR activities along with S-metabolites.
- •
The study illustrates first evidences on the effect of Si alleviating Cd toxicity in pea plants.
