Here we report the effects of three Bt-rice varieties and their non-Bt conventional isolines on biological traits including survival, reproduction, and the activities of three antioxidant enzymes superoxide dismutase, catalase and peroxidase, in the Collembolan, Folsomia candida. The reproduction was significantly lower when fed Kemingdao and Huahui1 than those feeding on their non-GM near-isogenic varieties Xiushui and Minghui63 respectively, this can be explained by the differences of plant compositions depended on variety of rice. The catalase activity of F. candida was significantly lower when fed the Bt-rice variety Kemingdao compared to the near-isogenic non-Bt-rice variety Xiushui. This suggests that some Bt-rice varieties may impose environmental stress to collembolans. We emphasize that changes in activity of antioxidant enzymes of non-target organisms are important in understanding the ecological consequences for organisms inhabiting transgenic Bt-rice plantations.
在这里，我们报告了三种转 Bt 水稻品种及其非转 Bt 对照系对三种弹尾目生物特征的影响，包括生存、繁殖和三种抗氧化酶超氧化物歧化酶、过氧化氢酶和过氧化物酶的活性。与喂食其非转基因近等基因品种秀水和明恢 63 相比，喂食克明道和华贵 1 的繁殖力显著降低，这可以用水稻品种的植物成分差异来解释。与非转 Bt 水稻品种秀水相比，转 Bt 水稻品种克明道处理的 Folsomia candida 过氧化氢酶活性显著降低。这表明一些转 Bt 水稻品种可能会对弹尾目动物造成环境压力。我们强调，非靶标生物抗氧化酶活性的变化对于理解栖息在转 Bt 水稻种植园中生物体的生态后果非常重要。
