dc.description.abstract | We generated transgenic tall fescue (Festuca arundinacea Schreb. cv. Kentucky-31) plants harboring a synthetic Myxococcus xanthus protoporphyrinogen oxidase (MxPPO) gene through Agrobacterium-mediated gene transfer. Successful integration of the transgene into the genome of transgenic plants confirmed by polymerase chain reaction (PCR) and Southern blot analysis, and the functional expression of the MxPPO gene at the mRNA level in transgenic lines was validated by Northern blot analysis. Responses of transgenic and non-transgenic tall fescue plants to diphenyl-ether herbicides such as oxyfluorfen and acifluorfen have been evaluated in respect of various physiological and biochemical parameters. Differential responses were observed in chlorophyll content, in vivo H2O2 deposition and lipid peroxidation in both transgenic and non-transgenic plants exposed to oxyfluorfen or acifluorfen. Isozyme profiles of four antioxidant-enzymes, including peroxidase (POD), catalase (CAT), superoxide dismutase (SOD) and ascorbate peroxidase (APX), were also investigated in transgenic and non-transgenic plants using native PAGE analysis. Compared to the transgenic lines, higher staining activities of the examined antioxidant-enzymes observed in non-transgenic plants subjected to 100 μM of oxyfluorfen or acifluorfen suggests that non-transgenic plants are unable to prevent the photodynamic induced oxidative stress caused by herbicides. In addition, both transgenic and non-transgenic plants exposed to oxyfluorfen exhibited proportionally increased band-staining patterns in contrast to acifluorfen, which suggests that oxyfluorfen has relatively greater or more rapid effects on leaves than acifluorfen. | - |
