Abstract

âº Chloroplastic and mitochondrial SOD and APX from leaf and inflorescence of Chenopodium album showed activity even after boiling temperature treatment. âº Chloroplastic and mitochondrial APX isozymes showing activity at boiling temperature are being reported for the first time. âº Thermostable SOD and APX in both chloroplast and mitochondria may contribute to heat tolerance in C. album.
