Abstract

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.

摘要

过量生产矮牵牛叶绿体 Cu/Zn 超氧化物歧化酶的转基因烟草（Nicotiana tabacum 品种 W38）植株暴露于会伤害对照烟草植株的臭氧剂量下。根据叶片损伤等级，转基因植株没有提供一致的保护。这些数据表明，单独增加叶绿体 Cu/Zn 超氧化物歧化酶的含量不足以降低臭氧毒性。
