基于16S rRNA研究铜污染对土壤细菌群落、抗生素抗性基因及基因转移的影响OACSTPCD
A 16S rRNA-based study of the effect of copper contamination on antibiotic resistance genes and horizontal gene transfer in soil bacterial communities
对经0、200、400 mg·kg-1 Cu2+处理的3个种植池土壤分别采样,并对所有样品进行16S rRNA高通量测序.结果表明:铜污染改变了土壤中的细菌群落结构,抗生素抗性基因(antibiotic resistance genes,ARGs)与基因水平转移(horizontal gene transfer,HGT)相关基因的丰度随Cu2+浓度的升高而增加.富集的抗性基因大多为多药耐药基因.这表明铜胁迫会改变土壤中细菌群落结…查看全部>>
In this study,soil samples were collected from three planting ponds treated with 0,200 and 400 mg Cu2+,respectively,and all samples were sequenced by 16S rRNA high-throughput sequencing.Sequencing results showed that Cu contamination changed the bacterial community structure in soil,and the abundance of antibiotic resistance genes(ARGs)and horizontal gene transfer(HGT)related genes increased with the increase of Cu2+concentration.The resul-ting antibiotic re…查看全部>>
