Polyamines and paraquat toxicity in Arabidopsis thaliana

Plant Cell Physiol. 1998 Sep;39(9):987-92. doi: 10.1093/oxfordjournals.pcp.a029463.

Abstract

The relationship between paraquat toxicity and polyamine levels was analyzed in Arabidopsis wild-type and gi-3 plants. Paraquat treatment led to an increase in putrescine, but not of spermidine and spermine content. Additionally, polyamine feeding offered high levels of protection against paraquat toxicity with spermidine being the most effective protectant.
