Nitric oxide, polyamines and Cd-induced phytotoxicity in wheat roots

Cadmium, polyamines and SNP elevated endogenous NO contents and reduced root growth rates. The NO-trapping agent cPTIO considerably reverted root growth inhibition confirming that NO was, at least in part, responsible for this inhibition. However, other ROS might also be involved in Cd and Spm phytotoxicity.
