摘要: 明确抗草甘膦转基因大豆AG5601对根际土壤微生物群功能多样性的影响,为转基因大豆的安全性评价提供基础数据。采用BIOLOG的方法,对抗草甘膦转基因大豆AG5601、亲本大豆SNK500和普通栽培大豆中黄13成熟期和残茬期的根际土壤微生物的碳源利用特征进行比较分析。AG5601成熟期的根际土壤微生物群落碳源利用能力显著高于SNK500,但与中黄13无显著差异;在残茬期,AG5601、SNK500和中黄13的根际土壤微生物群落碳源利用能力均无显著差异。功能多样性分析发现,成熟期的AG5601与中黄13在根际土壤微生物McIntosh指数和Simpson指数均显著高于SNK500,而残茬期,3种大豆的根际土壤微生物多样性差异不显著。主成分分析表明,AG5601与SNK500成熟期和残茬期的根际土壤微生物碳源利用在两主成分轴上的差异较小,碳源利用模式基本相同。本研究表明,抗草甘膦转基因大豆AG5601对根际微生物群落功能多样性无长期、显著性影响。

Abstract: This study aims to clarify the effects of Roundup Ready Soybean AG5601 on the functional diversity of microbial community in rhizospheric soil,for supplying basic information for the safety evaluation of transgenic soybean. BIOLOG method was applied to compare the carbon source utilization characteristics of rhizospheric microorganism among AG5601,their parent SNK500,and ordinary cultivated soybean Zhonghuang 13 at mature and stubble stage. In the mature stage,the carbon source utilization capacity of rhizospheric microbial community in AG5601 was significantly higher than that in SNK500;however,had no significant difference with that in Zhonghuang 13. At the stubble stage,there were no significant differences in the carbon source utilization capacity of rhizospheric microbial community among G5601,SNK500 and Zhonghuang 13. Functional diversity analysis found that the rhizosphere soil microbial diversity indices of Simpson(1/D)and Mcintosh(U)of AG5601 were significantly higher than those of SNK500 in the mature stage. In the stubble stage the differences in microbial diversity among 3 soybeans rhizosphere soil were insignificant. Principal component analysis indicated that there existed same in the carbon source utilization by the microbes in rhizosphere soils of SNK500 and AG5601 at the mature and stubble stage,suggesting the non-difference in the carbon source utilization pattern of the microbes during these processes. This study revealed that the effects of Roundup Ready soybean AG5601 on the diversity of microbial community in the rhizospheric soil were not significant.
