Over-expression of Trxo1 and cell viability under H2O2 stress
Ortiz-Espín et al. treat over-expressing PsTrxo1 tobacco (Nicotiana tabacum) BY-2 cells with H2O2 and find a significant delay in cell death compared to controls, which may in part be due to a decreased content of endogenous H2O2 in the over-expressing cells, in which changes in oxidative parameters and antioxidants are less extended after the oxidative treatment.
Selenium toxicity in plants (Botanical Briefing)
Van Hoewyk provides a framework on plant selenium toxicity, showing that both malformed selenoproteins and oxidative stress drive selenium-induced stress.
