A Meta-analysis of the known Global Distribution and Host Range of the Ralstonia Species Complex

Abstract

The Ralstonia solanacearum species complex is a group of genetically diverse plant wilt pathogens. We created a database that documents the reported global distribution and host range of Ralstonia clades (e.g. phylotypes and sequevars). In this sixth release, we have cataloged information from 353 sources that report one or more Ralstonia strains isolated from 113 countries or territories. Metadata for nearly 14,000 strains are available as a supplemental table. We continue to maintain this database and the RSSC KBase Narrative. More detailed information regarding specific methods can be found in previous versions of this living pre-print. Recent reports expand the known distribution of several lineages: Ralstonia syzygii subsp. syzygii in Brazil, Ralstonia syzygii subsp. celebesensis (Banana Blood Disease lineage) in continental Asia, and phylotype I in Europe. The interactive Ralstonia Diversity Dashboard https://ralstoniadashboard.shinyapps.io/ RalstoniaWiltDashboard/ ) has been updated with this new version of the dataset. Additionally, this version of the living pre-print has new visualizations.
