Corrigendum: Phylogenomic and comparative genomic studies robustly demarcate two distinct clades of Pseudomonas aeruginosa strains: proposal to transfer the strains from an outlier clade to a novel species Pseudomonas paraeruginosa sp. nov

Abstract

In the published version of this article the type strain of Pseudomonas paraeruginosa was incorrectly listed as NCTC 13628 T (=PA7 T =ATCC 9027 T ).However, while the strain PA7 belongs to the species Pseudomonas paraeruginosa, it differs from the other two listed type strains for this species.This corrigendum removes the PA7 as one of the type strains for P. paraeruginosa. The resulting corrections to the type strains in the published article are noted below.

Pseudomonas aeruginosa strains belonging to phylogroup 3 frequently exhibit an atypical quorum sensing response: the case of MAZ105, a tomato rhizosphere isolate

“…Strains belonging to P. aeruginosa phylogroup 3 have been proposed to constitute a different species ( Pseudomonas paraeruginosa ) due to their genetic distance from strains belonging to other P. aeruginosa phylogroups ( Fig. 1 ) [ 10 ]. However, even though strains belonging to clade 3 present characteristic genome features, such as deletions of genes involved in T3SS, of rhlC that encodes rhamnosyl-transferase II that converts mono- to di-RL and of phzH that encodes for the enzyme transforming the PYO precursor phenazine 1-carboxylic acid (PCA) to phenazine 1-carboxamide (PCN), among others [ 11 ], the biology of bacteria belonging to this phylogroup is the same as that of members of the other phylogroups.…”

“…This bacterial species is constituted by five phylogroups [7], four of which have a high degree of genomic conservation (clades 1, 2, 4 and 5), while the genetically diverse group 3 (PA7 group) has been defined as an outlier clade due to its high genetic sequence variability [7–9]. This group has recently been proposed to constitute a separate bacterial species [10]. However, strains belonging to any of the five P.…”

This group has recently been proposed to constitute a separate bacterial species [ 10 ]. However, strains belonging to any of the five P. aeruginosa phylogroups are potentially pathogenic even if isolated from environmental samples and show high conservation of strategies and traits involved in establishing pathogenic interactions [ 7, 9, 11 ].…”
