Resource Announcement of 18 Complete Genomes of Phylotype I Ralstonia pseudosolanacearum From Benin and Togo
The Ralstonia solanacearum species complex (RSSC) is a group of globally distributed plant pathogens. To investigate the diversity of RSSC pathogens in West Africa, we sequenced the genomes of eighteen strains from five locations in Benin and two locations in Togo, selected from a comprehensive regional survey, using long read Nanopore sequencing. Phylogenetic analysis of these strains revealed a major lineage of sixteen strains from Benin and Togo belonging to phylotype I sequevar 18 (seq. I-18), and a minor lineage of two strains isolated from Benin that belonged to seq. I-31. The seq. I-18 clade includes genomes of closely related strains from other West African and Southeast Asian countries. The two strains in the minor lineage were closely related to genomes isolated from Tanzania. Our data on the genetic diversity of the RSSC pathogens will help to inform the epidemiology of bacterial wilt in West Africa.
