“…For "P. zantedeschiae", the three strains hosted at CIRM-CFBP were all isolated from Araceae plants, as the other strains described for this species [27]. Concerning the recently described freshwater environmental species P. aquaticum [17], P. fontis [21] and P. polonicum [25] and the strain CFBP 8739, we were surprised that these species had either no representative in the CIRM-CFBP or only strains deposited following the recent description of the species. The fact that no strain representative of these species was isolated from crop plants and ornamentals along the 75-year period that covered our analysis strongly suggests that these species are not an important threat for crop plants and ornamentals.…”

Updated Taxonomy of Pectobacterium Genus in the CIRM-CFBP Bacterial Collection: When Newly Described Species Reveal “Old” Endemic Population

Bacterial collections are invaluable tools for microbiologists. However, their practical use is compromised by imprecise taxonomical assignation of bacterial strains. This is particularly true for soft rotting plant pathogens of the Pectobacterium genus. We analysed the taxonomic status of 265 Pectobacterium strains deposited at CIRM-CFBP collection from 1944 to 2020. This collection gathered Pectobacterium strains isolated in 27 countries from 32 plant species representing 17 botanical families or from nonhost environments. The MLSA approach completed by genomic analysis of 15 strains was performed to update the taxonomic status of these 265 strains. The results showed that the CIRM-CFBP Pectobacterium collection harboured at least one strain of each species, with the exception of P. polonicum. Yet, seven strains could not be assigned to any of the described species and may represent at least two new species. Surprisingly, P. versatile, recently described in 2019, is the most prevalent species among CIRM-CFBP strains. An analysis of P. versatile strains revealed that this species is pandemic and isolated from various host plants and environments. At the opposite, other species gathered strains isolated from only one botanical family or exclusively from a freshwater environment. Our work also revealed new host plants for several Pectobacterium spp.

“…In addition, new Pectobacterium species were progressively described, most of them recently on the basis of whole genome sequence analysis. Today, the Pectobacterium genus encompasses 17 recognized species Pectobacterium actinidiae [15], Pectobacterium aquaticum [17], Pectobacterium aroidearum [18], Pectobacterium atrosepticum [14], Pectobacterium betavasculorum [14], Pectobacterium brasiliense [15], Pectobacterium cacticida [9,19], Pectobacterium carotovorum [8,15,20], Pectobacterium fontis [21], Pectobacterium odoriferum [15], Pectobacterium parmentieri [22], Pectobacterium parvum [23], Pectobacterium polaris [24], Pectobacterium polonicum [25], Pectobacterium punjabense [26], Pectobacterium versatile [15] and Pectobacterium wasabiae [14] and 2 proposed species not yet validated by had hoc committees:…”

Bacterial collections are invaluable tools for microbiologists. However, their practical use is compromised by imprecise taxonomical assignation of bacterial strains. This is particularly true for soft rotting plant pathogens of the Pectobacterium genus. To solve this difficulty, we analyzed the taxonomic status of 265 Pectobacterium strains deposited at CIRM-CFBP collection from 1944 to 2020. This collection gathered Pectobacterium strains isolated in 27 countries from 32 plant species representing 17 botanical families or from non-host environments. MLSA approach completed by genomic analysis of 15 strains was performed to update the taxonomic status of these 265 strains. Results showed that the CIRM-CFBP Pectobacterium collection harboured at least one strain of each species to the exception of P. polonicum. Yet, 6 strains could not be assigned to any of the described species and may represent at least two new species. Surprisingly, the P. versatile species, recently described in 2019, is the most prevalent species among CIRM-CFBP strains. Analysis of P. versatile strains revealed that this species is endemic all over the world on various host plants and environments. At the opposite, other species gathered strains isolated from only one botanical family or exclusively from fresh water environment. Our work also revealed new host plants for several Pectobacterium spp.

“…According to the present taxonomy, the genus now includes 18 species: P. actinidiae, P. aquaticum, P. aroidearum, P. atrosepticum , P. betavasculorum, P. brasiliense, P. cacticida , P. carotovorum , P . odoriferum , P. parmentieri, P. parvum, P. peruviense, P. polaris, P. polonicum, P. punjabense, P. versatile, P. wasabiae and P. zantedeschiae, [ 4 , 7 , 8 , 9 , 10 , 11 ]. In spite of the clarifying taxonomy, the mechanisms underlying this natural segregation are largely unexplored.…”

Host Specificity and Differential Pathogenicity of Pectobacterium Strains from Dicot and Monocot Hosts

et al. 2020

Recent phylogenetic studies have transferred certain isolates from monocot plants previously included in the heterogeneous group of Pectobacteriumcarotovorum (Pc) to a species level termed Pectobacterium aroidearum. The specificity of Pectobacterium associated infections had received less attention, and may be of high scientific and economic importance. Here, we have characterized differential responses of Pectobacterium isolates from potato (WPP14) and calla lily (PC16) on two typical hosts: Brassica oleracea var. capitata (cabbage) a dicot host; and Zantedeschia aethiopica (calla lily) a monocot host. The results revealed clear host specific responses following infection with the two bacterial strains. This was demonstrated by differential production of volatile organic compounds (VOCs) and the expression of plant defense-related genes (pal, PR-1, lox2, ast). A related pattern was observed in bacterial responses to each of the host’s extract, with differential expression of virulence-related determinants and genes associated with quorum-sensing and plant cell wall-degrading enzymes. The differences were associated with each strain’s competence on its respective host.
