| Popis: | Effect of cold on antioxidant responses in aerial (shoots and leaves) and roots tissues of two contrasting accessions of M. ciliaris Krockers (Cil 126, tolerant and Cil 123, sensible) were investigated. Ten-day-old grown seedlings were subjected at different periods of cold acclimation (4°C) 2, 4, and 6 days. Peroxidases (POD) (EC 1.11.1.7) activities and isoenzymes expression of plantlets treated and control (23°C) of the aerial (shoot+leaves) and root vegetative tissues were carried. Global peroxidase activity under low temperature stress was higher in tolerant ecotype than sensible one. The same trend was also observed at expressed isoenzymes. On the other hand, whether in tolerant or sensitive, activity and isoenzymes peroxidase was more pronounced at the roots than in aerials tissues system. |
