Interpretive Summary: Dickeya dianthicola causes blackleg and soft rot in a wide variety of field and ornamental crops. These diseases cause significant economic loss in the US and around the world. Here, we report the complete genome sequence of D. dianthicola 67-19, which was originally isolated from New Guinea Impatiens in Long Island, NY. This sequence and its annotation are now publicly available and are being used to help better understand blackleg and soft rot diseases in impatiens and other specialty crops, such as potatoes.

Technical Abstract: New Guinea Impatiens (NGI, Impatiens hawkeri) are popular bedding plants. Using 16S rDNA sequencing and genus-specific PCR, we previously reported Dickeya dianthicola strain 67-19 causing blackleg symptoms on NGI. Here, we report a high-quality complete and annotated genome sequence of D. dianthicola 67-19. The 4,851,809'bp genome was assembled with Nanopore reads and polished with Illumina reads, yielding 422× and 105× coverage, respectively. This closed genome provides a resource for future research on comparative genomics and biology of D. dianthicola and related species.
