dc.description.abstract | To analyze the physiological role of each peroxidase (POD) isoenzyme in environmental stress adaptation, transgenic tobacco (Nicotiana tabacum) plants expressing either a sweet potato (Ipomoea batatas) anionic POD (swpa1) or neutral POD (swpn1) were tested for responses to oxidant methyl viologen (MV). Fully expanded leaves of both swpa1- and swpn1-transgenic plants had about two times higher POD activity than non transformed (NT) plants. When tobacco leaf discs were subjected to MV at 10 and 100 μmol/L, swpa1-transgenic plants showed about a 25 % reduction in membrane damage relative to swpn1-transgenic or NT plants. Leaves of swpn1-transgenic and NT plants were bleached more than those of swpa1-transgenics by 1 μmol/L MV treatment, whereas all plants were severely damaged at 3 μmol/L MV. These results indicate that the increased H2O2-scavenging capacity provided by the swpa1 POD (a guaiacol-type POD) contributes to increased protection against MV-mediated oxidative damage. Furthermore, differences in response to oxidant treatments indicate unique functions for the two isoenzymes encoded by swpa1 and swpn1. | - |
