Pangenomic type III effector database of the plant pathogenic <i>Ralstonia</i> spp.

Abstract

We curated the T3E repertoires of 12 plant pathogenic <i>Ralstonia</i> strains, representing a total of 12 strains spread over the different groups of the species complex. This generated a pangenome repertoire of 102 T3E genes and 16 hypothetical T3E genes. Using this database, we scanned for the presence of T3Es in the 155 available genomes representing 140 distinct plant pathogenic <i>Ralstonia</i> strains isolated from different host plants in different areas of the globe. All this information is presented in a searchable database. A presence/absence analysis, modulated by a strain sequence/gene annotation quality score, enabled us to redefine core and accessory T3E repertoires.
