چکیده

Transgenic tobacco (Nicotiana tabacum cultivar W38) plants that overproduce petunia chloroplastic Cu/Zn superoxide dismutase were exposed to ozone dosages that injure control tobacco plants. Based on foliar injury ratings, there was no consistent protection provided to the transgenic plants. These data indicate that an increase in the chloroplastic Cu/Zn superoxide dismutase alone is not sufficient to reduce ozone toxicity.

Enhancement of oxidative stress tolerance in transgenic tobacco plants overproducing Fe-superoxide dismutase in chloroplasts.

A chimeric gene consisting of the coding sequence for chloroplastic Fe superoxide dismutase (FeSOD) from Arabidopsis thaliana, coupled to the chloroplast targeting sequence from the pea ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit, was expressed in Nicotiana tabacum cv Petit Havana SR1. Expression of the transgenic FeSOD protected both the plasmalemma and photosystem II against...

Antisense and RNAi expression for a chloroplastic superoxide dismutase gene in transgenic plants

The cDNA of tomato chloroplastic Cu/Zn-superoxide dismutase was used to construct transgenic tobacco (Nicotiana plumbaginifolia). It was found that the gene expression of Cu/Zn-superoxide dismutase can constitutively be reduced in the transgenic tobacco plants because of double-stranded (dsRNA) expressed in the form of intronspliced hairpin structures and antisense suppression. Furthermore, the...

Differential accumulation of antioxidant mRNAs in Arabidopsis thaliana exposed to ozone.

Antioxidant isoenzymes function to eliminate free radicals and are localized to several different subcellular compartments within the plant cell. In Arabidopsis thaliana exposed to ozone (O3), we have monitored the accumulation of mRNAs encoding both cytosolic and chloroplastic antioxidant isoenzymes. Two different O3 exposure protocols yielded similar results. Upon O3 exposure, the steady-stat...

Maintenance of Normal Stress Tolerance in the Moss Physcomitrella patens Lacking Chloroplastic CuZn-Superoxide Dismutase

Superoxide dismutases (SODs) catalyze the dismutation of superoxide and play an important role in reducing oxidative stress in plants. Based on in-gel SOD activity staining, chloroplasts of the moss Physcomitrella patens have two CuZn-SODs as the major SOD isozymes and minor SODs, including a Fe-SOD and two Mn-SODs. To investigate the contribution of chloroplastic SODs to stress tolerance in P....

Site- and cell-specific alteration of lung copper/zinc and manganese superoxide dismutases by chronic ozone exposure.

The antioxidant enzymes copper/zinc (Cu-Zn) and manganese (Mn) superoxide dismutase (SOD) have been implicated in protection of the lungs from oxidant damage. Mn SOD in particular may be related to acquired tolerance in cells following chronic ozone exposure. In order to study these protective and adaptive phenomena in oxidant injury, the cellular location and relative abundance of Mn SOD and C...
