eLibrary of Microbial Systematics and Genomics

eLMSG (eLibrary of Microbial Systematics and Genomics) is a web microbial library that integrates not only taxonomic information, but also genomic information and phenotypic information (including morphology, physiology, biochemistry and enzymology). The taxonomic system of eLMSG is manually curated and composed of all validly and some effectively published taxa. For each taxon, the Latin name, taxon ID (NCBI taxonomy), etymology, rank, lineage, the dates of effective and/or valid publication, feature descriptions, nomenclature type and references for the proposal and emendations during the history of the taxon are presented. Besides these data, the species taxa contain information about 16S rRNA gene and/or genome sequences. All publicly available genome data of each type species including both type and non-type strains were collected, and if needed, re-annotated using the standardized analysis pipeline. Furthermore, pan-genomic data analyses were conducted for species with ≥5 genome sequences available. Finally, for all type species, taxonomically relevant phenotypic data were extracted and curated from literatures, which were further indexed into eLMSG as searchable and analyzable data records. Taken together, eLMSG is a comprehensive web platform for studying mi- crobial systematics and genomics, potentially useful for better understanding microbial taxonomy, natural evolutionary processes and ecological relationships.

eLMSG（微生物系统学和基因组学电子图书馆）是一个综合性的网络微生物数据库，它不仅整合了分类学信息，还包括基因组信息和表型信息（包括形态学、生理学、生物化学和酶学）。eLMSG的分类体系经过人工审校，由所有有效及部分有效发表的物种组成。对于每个物种，其学名、物种ID（NCBI分类学）、词源、等级、谱系、有效或正式发表的日期、特征描述、命名学类型以及物种历史中提议和修订的参考文献均予以呈现。除此之外，物种分类中还包含了16S rRNA基因和/或基因组序列的信息。收集了所有公开可用的包括典型菌株和非典型菌株在内的各类物种基因组数据，并在必要时，通过标准化的分析流程进行重新注释。此外，对于拥有≥5个基因组序列的物种，还进行了全基因组数据分析。最后，从文献中提取并整理了所有典型物种的与分类学相关的表型数据，并将其作为可搜索和可分析的数据记录索引到eLMSG中。总之，eLMSG是一个研究微生物系统学和基因组学的全面网络平台，有助于更深入地理解微生物分类学、自然进化过程和生态关系。
