High-Quality Complete Genome Resource of Plant-Pathogenic Bacterium Dickeya solani IPO 2019, Isolated from Hyacinthus orientalis

Dickeya solani is an emerging plant-pathogenic bacterium causing disease symptoms in a variety of agriculturally relevant crop species worldwide. To date, a number of D. solani genomes have been sequenced and characterized; the great majority of these genomes have, however, come from D. solani strains isolated from potato (Solanum tuberosum L.) and not from other plant hosts. Herewith, we present the first complete, high-quality genome of D. solani IPO 2019 (LMG 25990), isolated from the ornamental plant Hyacinthus orientalis. The genome of D. solani IPO 2019 consists of one chromosome of 4,919,542 bp, with a GC content of 56.2% and no plasmids. The genome contains 4,502 annotated features, 22 ribosomal RNA genes, 73 transfer RNA genes, and one CRISPR. We believe that the information on this high-quality, complete, closed genome of D. solani strain isolated from a host plant different from potato (i.e. hyacinth) will provide resources for comparative genomic studies and for analyses targeting adaptation and ecological fitness mechanisms present in Dickeya solani species.

Automated summary

Dickeya solani is an emerging plant-pathogenic bacterium causing disease symptoms in various agriculturally relevant crop species. Most sequenced genomes of D. solani strains come from potato, but this study presents the first complete high-quality genome of D. solani IPO 2019 isolated from an ornamental plant, providing valuable resources for comparative genomic studies.
