摘　　要：转基因技术在提高作物抗逆性、增加粮食产量方面贡献卓越的同时,对包括土壤微生物群落在内的土壤生态系统的风险评估一直存在争议。大多数研究表明,转基因作物的种植会引起土壤微生物群落多样性的变化,但其对土壤微生物群落多样性的影响程度、持续作用时间等都没有定论。综述了外源基因及其表达产物进入作物根际的方式与不同类型外源基因及其表达产物对土壤微生物群落多样性的影响;并对转基因作物影响土壤微生物群落的研究手段进行了讨论,提出了下一步的研究策略。Transgenic technology plays an important role on improving crops resistance and increasing food production, but the risk assessment about transgenic crops on soil ecosystem in which microorganisms are involved has been controversial. Most studies showed that transgenic crops could affect the soil microbial community diversity. However, the degree and time of the affected were not settled yet.This paper summarized the ways which the exogenous gene and their expression products entered crop rhizosphere and the effects of different transgenic crops on soil microbial community diversity. And it discussed the research technologies about the effects and proposed strategy of the future.
