Draft Genome Sequence of Photorhabdus luminescens Strain BA1, an Entomopathogenic Bacterium Isolated from Nematodes Found in Egypt

Abstract

Photorhabdus luminescens strain BA1 is an entomopathogenic bacterium that forms a symbiotic association with Heterorhabditis nematodes. We report here a 5.0-Mbp draft genome sequence for P. luminscens strain BA1, with a G+C content of 42.46% and 4,250 candidate protein-coding genes.

Photorhabdus heterorhabditis subsp. aluminescens subsp. nov., Photorhabdus heterorhabditis subsp. heterorhabditis subsp. nov., Photorhabdus australis subsp. thailandensis subsp. nov., Photorhabdus australis subsp. australis subsp. nov., and Photorhabdus aegyptia sp. nov. isolated from Heterorhabditis entomopathogenic nematodes

“…However, there are still several taxonomic uncertainties, especially regarding bacterial strains that are highly similar to the type strain of the species that they were circumscribed or that were not formally characterized at the taxonomic level. This is the case of at least three bacterial strains: BA1, PB68.1 and Q614 [12,[25][26][27][28]. They were isolated from the intestines of Heterorhabditis EPNs that were recovered from soil samples in Egypt, Thailand and Australia, respectively.…”

“…As the full genome sequences of certain type strains are not publicly available, the set of strains used to reconstruct phylogenetic relationships based on 16S rRNA gene sequences, whole genome sequences and biochemical tests are slightly different. Genome sequences of BA1 T , Q614 T and PB68.1 T were obtained as described previously [6,16,17,25]. Whole genome sequence similarities were calculated by the digital DNA-DNA hybridization (dDDH) method using formula 2 of the Genome-to-Genome Distance Calculator (GGDC) web service of the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH (DSMZ) [31][32][33][34].…”

Permanent Draft Genome Sequence of Photorhabdus temperata Strain Hm, an Entomopathogenic Bacterium Isolated from Nematodes

“…Our understanding of these bacteria has been greatly enhanced by genome sequencing of the three established species, including that of P. luminescens TT01 ( 16 ), P. asymbiotica ATCC 43949 ( 17 ), P. temperata subsp. khanii NC19 ( 18 ), P. temperata Meg1 ( 19 ), P. luminescens BA1 ( 20 ), P. luminescens subsp. laumondii HP88 ( 21 ), P. asymbiotica Kingcliff ( 22 ), P. temperata subsp.…”

Draft Genome Sequence of Photorhabdus luminescens subsp. laumondii HP88, an Entomopathogenic Bacterium Isolated from Nematodes

“…Based on molecular analysis, the Photorhabdus genus is divided into three bacterial species: P. luminescens , P. temperata , and P. asymbiotica ( 15 , 16 ). Our understanding of these bacteria has been greatly enhanced by the genome sequencing of strains from all three established species: P. luminescens TT01 ( 17 ), P. asymbiotica ATCC 43949 ( 18 , 19 ), P. temperata NC19 ( 20 ), P. temperata Meg1 ( 21 ), P. luminescens BA1 ( 22 ), P. asymbiotica Kingcliff ( 23 ), and P. temperata M121 ( 24 ). Here, we present a draft genome sequence for P. luminescens subsp.…”
