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，与多种表型性状相关，包括毒力、适合度提升以及抗菌药物耐药性。其在微生物种群内部及跨物种间的遗传物质传递过程中发挥着关键作用。诸如质粒在内的移动遗传因子（Mobile genetic elements）的研究因其生态学、生物学与临床层面的重要意义而备受学界关注。RefSeq质粒序列数据集收录了源自不同细菌菌株的完整序列，并按照宿主物种进行分类组织。
