- •
Arsenic(V) could be reduced and subsequently methylated in Panax notoginseng.
- •
The reduction and methylation of As in the root were promoted by low As toxic stress, but were impeded by high As toxic stress.
- •
The translocation of total As, As(III), and MMA from the root to the rhizome was a response to As toxic stress.
