A role for APX1 gene in lead tolerance in Arabidopsis thaliana

Lead (Pb) is a dangerous and widespread metal pollutant. Numerous studies have been made in understanding heavy metal detoxification and tolerance in plants, however, relatively few are known about the mechanisms involved in Pb stress response. In this study, we provide evidence for a novel role of APX1 gene in Pb tolerance in Arabidopsis. KO-APX1 mutants apx1-3 and apx1-4 showed more resistant than wild type, and the APX1-complementary COM1...
