摘要: 转基因作物对土壤生态系统的影响日益引起人们的广泛关注。采用Biolog ECO微平板对转基因抗虫玉米IE09S034及其对应的受体玉米根际微生物群落碳代谢功能进行了比较研究。结果表明,转基因抗虫玉米IE09S034对根际微生物碳代谢功能无显著性影响,且发现年份和生育期是引起根际微生物碳代谢情况变化的主要因素。本文为转基因抗虫玉米IE09S034的环境安全性评估提供了新的依据。

Abstract: With the increase of genetically modified (GM) crops area, their biosafety for soil ecosystems has become a controversial issue. This paper compared the functional diversity of rhizosphere microbial communities between GM Bt maize IE09S034 and its non-GM parental maize Zong31 by Biolog ECO microplate. Results indicated that there was no difference between IE09S034 and Zong31 in the functional diversity of microbial communities in rhizosphere soil. Besides, year and plant growth stage had stronger effect than cultivar. It was concluded that GM maize IE09S034 did not alter the functional diversity of microbial communities in rhizosphere soil.
