Genetically modified (GM) crops have brought various economic benefits but may also have adversely affected soil microorganisms. To examine whether transgenic high-methionine soybean ZD91 alters the bacterial community structure in the rhizosphere, we performed a 2-year follow-up study using the transgenic high-methionine soybean cultivar ZD91 and wild type cultivar ZD. The community composition and the relative abundance of bacteria in rhizosphere soil were determined by sequencing of the 16S rRNA amplicon. Our results indicated that transgenic soybean ZD91 had no significantly effects on rhizosphere bacterial communities. Instead, the plant growth stage and year appeared to have a stronger effect on bacterial communities. Our findings therefore provided reliable scientific evidence for potential commercial cultivation of cultivar ZD91.
转基因（GM）作物带来了各种经济效益，但也可能对土壤微生物产生不利影响。为了研究转高蛋氨酸大豆 ZD91 是否改变了根际土壤中的细菌群落结构，我们使用转高蛋氨酸大豆品种 ZD91 和野生型品种 ZD 进行了为期两年的后续研究。通过 16S rRNA 扩增子测序，确定了根际土壤中细菌的群落组成和相对丰度。我们的结果表明，转基因大豆 ZD91 对根际细菌群落没有显著影响。相反，植物生长阶段和年份似乎对细菌群落的影响更强。因此，我们的研究结果为品种 ZD91 的潜在商业种植提供了可靠的科学依据。
