Bacterial plasmids are self-replicating, extrachromosomal elements associated with a variety of phenotypic traits including virulence, enhanced fitness, and resistance to antimicrobial agents. They play an important role in the transfer of genetic material in microbial populations within and between the species. The study of mobile genetic elements such as plasmids is of particular interest because of their ecological, biological, and clinical significance. The Refseq collection of plasmids represent complete sequences derived from different bacterial strains and is organized by host organism at the species level.

细菌质粒（bacterial plasmids）是一类可自主复制的染色体外遗传因子（extrachromosomal elements），与多种表型性状相关，包括毒力、适合度增强以及抗菌剂抗性。它们在微生物种群内部及物种间的遗传物质转移过程中发挥着重要作用。鉴于可移动遗传元件（mobile genetic elements）具有重要的生态学、生物学与临床意义，对包括质粒在内的这类元件的研究备受学界关注。本RefSeq质粒集（Refseq）收录了源自不同细菌菌株的完整序列，并按照宿主物种水平的生物体进行分类组织。
