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）是一类可自我复制的染色体外遗传元件，可介导多种表型性状，包括致病性、适应性提升以及抗微生物剂耐药性。其在微生物种群的种内与种间遗传物质转移过程中发挥着关键作用。鉴于移动遗传元件（mobile genetic elements）在生态、生物学及临床领域均具有重要意义，针对包括质粒在内的移动遗传元件的研究备受关注。RefSeq质粒数据集收录了源自不同细菌菌株的完整序列，并依据宿主物种层级完成分类组织。
