Abstract
ABSTRACTErwinia chrysanthemi S3-1 is a bacterial soft rot pathogen of the white-flowered calla lily. The complete genome sequence of the strain was determined and used to reclassify the strain as Dickeya dadantii subsp. dieffenbachiae. The sequence will be useful to study plant host-driven speciation in strains of D. dadantii.
Highlights
Erwinia chrysanthemi S3-1 is a bacterial pathogen with a higher virulence on whiteflowered calla lily (Zantedeschia aethiopica) than other E. chrysanthemi strains [1, 2]
The average nucleotide identity (ANI) and in silico DNA-DNA hybridization (isDDH) values were calculated by comparing the genome sequence of strain S3-1 with that of each type species of Dickeya, using the ANI Calculator (OAU v1.2) with the OrthoANIu algorithm [16] and a pipeline for isDDH [13]
The species threshold was set to 96% for ANI and 70% for isDDH [12, 13]
Summary
Erwinia chrysanthemi S3-1 is a bacterial pathogen with a higher virulence on whiteflowered calla lily (Zantedeschia aethiopica) than other E. chrysanthemi strains [1, 2]. The assembled genome is a 5,065,613-bp circular chromosome (G1C content, 56.5%) and was annotated using the NCBI Prokaryotic Genome Annotation Pipeline v5.2 [15]. The chromosome contains 4,337 predicted coding sequences.
