Abstract

The Enterobacter cloacae complex is genetically very diverse. The increasing number of complete genomic sequences of E. cloacae is helping to determine the exact relationship among members of the complex. E. cloacae P101 is an endophyte of switchgrass (Panicum virgatum) and is closely related to other E. cloacae strains isolated from plants. The P101 genome consists of a 5,369,929 bp chromosome. The chromosome has 5,164 protein-coding regions, 100 tRNA sequences, and 8 rRNA operons.

Highlights

  • Numerous Enterobacter cloacae strains have been associated with plants as agents of disease [1,2,3,4], but E. cloacae strains have been associated with plants as endophytes [5,6,7,8], used for biocontrol of fungal pathogens [9,10,11,12,13,14,15,16], and associated with nosocomial infections in hospital settings [17,18,19]

  • E. cloacae is in the E. cloacae complex, which includes the Enterobacter species of E. asburiae, E. hormaechei, E. kobei, E. ludwigii, and E. nimipressuralis

  • Previous phylogenetic studies with multi-locus sequence analyses of common housekeeping genes demonstrate that there is considerable diversity among the strains designated as E. cloacae due to the formation of multiple clades and the fact that only 3% of the strains group with the type strain E. cloacae subsp. cloacae ATCC 13047 [17,18]

Summary

Introduction

Numerous Enterobacter cloacae strains have been associated with plants as agents of disease [1,2,3,4], but E. cloacae strains have been associated with plants as endophytes [5,6,7,8], used for biocontrol of fungal pathogens [9,10,11,12,13,14,15,16], and associated with nosocomial infections in hospital settings [17,18,19]. Evidence codes – IDA: Inferred from Direct Assay (first time in publication); TAS: Traceable Author Statement (i.e., a direct report exists in the literature); NAS: Non-traceable Author Statement (i.e., not directly observed for the living , isolated sample, but based on a g enerally accepted property for the species, or anecdotal evidence). New next-generation DNA sequencing data for P101 was obtained at the Laboratory for Biotechnology and Bioanalysis at Washington State University using the PacBio RS platform and the PCR products generated to confirm the genome assembly were sequenced at Elim Biopharmaceuticals (Hayward, CA).
