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元件，与多种表型性状相关，涵盖毒力、适合度增强以及抗微生物剂耐药性。其在微生物种群内部及跨物种的遗传物质转移过程中发挥关键作用。由于质粒这类可移动遗传元件（mobile genetic elements）具有重要的生态学、生物学与临床价值，相关研究备受学界关注。RefSeq质粒参考序列集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进行分类编排。
