Glutathion-S-Transferase activity in zea mais seedlings under high temperature and heavy metals combine action

Abstract

In model experiment the changes of Glutathione-S-Transferase (GST) activity in Zea maise seeds and seedlings under high temperature, and lead and cadmium ions combine action were investigated. Tissue-specific dynamics of enzymatic activity under two factors’ combine action was revealed. The dependence of enzyme’s activity level in seedlings’ organs from influence of cadmium and lead ions under short-term action of high temperature was shown. The enhancing of heavy metals detoxification process in seedlings under long-term action of high temperature was concluded.
