BACTOTRAITS-Scripts&database2026

We present the comprehensive BactoTraits database (updated version of the one described in Cébron et al. 2021), comprising 31 functional traits of bacteria using information from BacDive, rrnDB and genomesizeR. It now offers more traits for more strains (97,721 strains with at least one trait described) and makes R scripts available to the scientific community (script downloading available). These traits include physiological characteristics, metabolic processes, genome properties and biotope preferences. They could be inferred to the whole bacterial community thanks to taxonomic affiliation obtained from traditional high throughput 16S rRNA gene amplicon sequencing methods. This taxonomic affiliation is based on the regularly updated SILVA database and thus allows to study combinations of weighted mean trait profiles of bacterial communities at different taxonomic levels. BactoTraits can be used, for example, to improve predictions of ecological responses to natural/anthropogenic pressures and to support biomonitoring, management and conservation strategies. R scripts are autonomous and can be run by everyone. All the detailed information about the scripts, the choices made and the possible application are detailed in Laderriere, V., Usseglio-Polatera, P., Maunoury-Danger, F., & Cébron, A.

背景概述

BACTOTRAITS-Scripts&database2026是一个由CNRS国家科学研究中心发布的综合性细菌功能性状数据库，包含31个功能性状，覆盖97,721个菌株，并提供了R脚本工具。该数据集基于BacDive、rrnDB和genomesizeR信息，旨在通过16S rRNA基因测序方法推断细菌群落的功能多样性，支持生态研究、生物监测和管理策略。
