Chilling, oxidative stress and antioxidant enzyme responses in Arabidopsis thaliana

Abstract

SynopsisAlthough chilling of Arabidopsis thaliana cells to 4°C reduced respiration and superoxide generation, the latter still appears significant. Superoxide may contribute to the observed chilling-induced cellular lipid peroxidation and through processes that may be facilitated by the up-regulation of Cu,Zn-superoxide dismutase activity.
