Complete Genome Sequence of Dickeya dianthicola ME23, a Pathogen Causing Blackleg and Soft Rot Diseases of Potato

Abstract

In 2014, an outbreak of potato blackleg and soft rot disease emerged in North America and continues to impact potato production. Here, we report the annotated genome sequence of Dickeya dianthicola ME23, a strain hypothesized to be representative of the bacterial population responsible for this disease outbreak.

Genome-Wide Identification of Genes Important for Growth of Dickeya dadantii and Dickeya dianthicola in Potato (Solanum tuberosum) Tubers

“…While these three strains are all pathogenic on potato, Dda 3937 was originally isolated from Saintpaulia ionantha ( Lemattre and Narcy, 1972 ), and Ddia 6719 was recently isolated from New Guinea impatiens ( Impatiens hawkeri ) ( Liu et al, 2020a , b ). Dda 3937 has been a model strain used for molecular studies since its isolation in 1972 ( Lemattre and Narcy, 1972 ), while Ddia ME23 was isolated as a representative strain for a 2014 potato disease outbreak ( Ma et al, 2019 ). Pairwise ANI between Dda 3937 and Ddia ME23 is 92.8% ( Chen et al, 2019 ).…”

Genomic and morphological characteristics of the cold-adapted bacteria Mycetocola saprophilus provide insights into the pathogenesis of soft rot in Flammulina velutipes

“…To further understand the pathogenic mechanisms of soft rot disease, the complete genomes of some pathogenic bacteria strains have recently been sequenced and analyzed, including that of Erwinia persicina B64, which causes soft rot in onions [16], and that of Dickeya dianthicola ME23, which causes soft rot in potatoes [17]. However, the pathogenic mechanisms of soft rot disease in F. velutipes have not been elucidated.…”

Editorial: Genome-Wide Analyses of Pectobacterium and Dickeya Species

“…(Adeolu et al, 2016 ), are among the top 10 bacterial plant pathogens that limit crop yields and threaten global food security worldwide (Mansfield et al, 2012 ). Species within both genera are globally distributed (Mansfield et al, 2012 ; Ma et al, 2019 ; Boluk et al, 2021 ) and cause significant damage to both monocots and dicots, particularly to potato with potential global losses in production (Agrios, 2006 ), and an estimated cost of US$50–100 million annually in vegetables, fruits, and ornamental plants (Perombelon and Kelman, 1980 ; Pérombelon, 2002 ; Ma et al, 2007 ). Species in both genera have been isolated from infected plant tissues, soil, and water (Glasner et al, 2008 ; Hugouvieux-Cotte-Pattat et al, 2019 ; Oulghazi et al, 2019 ) as well as from alternative non-agricultural plant hosts (Fikowicz-Krosko et al, 2017 ; Fikowicz-Krosko and Czajkowski, 2018 ).…”
