Draft whole-genome sequence of the fluorene-degrading Sphingobium sp. strain LB126, isolated from polycyclic aromatic hydrocarbon-contaminated soil.

We report here the draft whole-genome sequence of a fluorene-degrading bacterium, Sphingobium sp. strain LB126. The genes involved in the upper biodegradation pathway of fluorene are located on a plasmid, and the lower pathway that generates tricarboxylic acid cycle intermediates is initiated by the meta-cleavage of protocatechuic acid that is chromosomally encoded.

Next-generation sequencing of Haematococcus lacustris reveals an extremely large 1.35-megabase chloroplast genome.

Haematococcus lacustris is an industrially relevant microalga that is used for the production of the carotenoid astaxanthin. Here, we report the use of PacBio long-read sequencing to assemble the chloroplast genome of H. lacustris strain UTEX:2505. At 1.35?Mb, this is the largest assembled chloroplast of any plant or alga known to date. Copyright © 2018 Bauman et al.

Draft genome sequence of Bacillus velezensis Lzh-a42, a plant growth- promoting rhizobacterium isolated from tomato rhizosphere.

The plant growth-promoting rhizobacterium Bacillus velezensis strain Lzh-a42, which has antimicrobial activity, was isolated from tomato rhizosphere. Here, we report its genome sequence, which includes several predicted functional genes related to secondary metabolite biosynthesis, antimicrobial activity, and biofilm synthesis.

Complete genome sequence of the symbiotic strain Bradyrhizobium icense LMTR 13T, isolated from lima bean (Phaseolus lunatus) in Peru.

The complete genome sequence of Bradyrhizobium icense LMTR 13T, a root nodule bacterium isolated from the legume Phaseolus lunatus, is reported here. The genome consists of a circular 8,322,773-bp chromosome which codes for a large and novel symbiotic island as well as genes putatively involved in soil and root colonization.

Draft genome sequence and annotation of the phytopathogenic Ralstonia pickettii (previously Burkholderia glumae) strain ICMP-8657.

Strain ICMP-8657 was formerly taxonomically classified as Burkholderia glumae and reported to be the producer of an antibacterial pyrazole derivative. Here, we report the draft genome sequence of ICMP-8657, which failed to demonstrate the biosynthetic capacity to produce the stated antibacterial compound, leading to its taxonomic reclassification as Ralstonia pickettii ICMP-8657.

Complete genome sequence of a ciprofloxacin-resistant Salmonella enterica subsp. enterica serovar Kentucky sequence type 198 strain, PU131, isolated from a human patient in Washington State.

Strains of the ciprofloxacin-resistant (Cipr) Salmonella enterica subsp. enterica serovar Kentucky sequence type 198 (ST198) have rapidly and extensively disseminated globally to become a major food safety and public health concern. Here, we report the complete genome sequence of a CiprS. Kentucky ST198 strain, PU131, isolated from a human patient in Washington State (USA).

Draft genome sequence of Streptomyces sp. strain DH-12, a soilborneisolate from the Thar Desert with broad-spectrum antibacterial activity.

Strain DH-12 exhibits broad-spectrum antibacterial activity toward Gram-positive and Gram-negative pathogens. The 7.6-Mb draft genome sequence gives insight into the complete secondary metabolite production capacity and reveals genes putatively responsible for its antibacterial activity, as well as genes which enable the survival of the organism in an extreme arid environment.

Whole-genome sequence of phage-resistant strain Escherichia coli DH5a.

The genomes of many strains of Escherichia coli have been sequenced, as this organism is a classic model bacterium. Here, we report the genome sequence of Escherichia coli DH5a, which is resistant to a T4 bacteriophage (CCTCC AB 2015375), while its other homologous E. coli strains, such as E. coli BL21, DH10B, and MG1655, are not resistant to phage invasions. Thus, understanding of the genome of the DH5a strain, along with comparative analysis of its genome sequence along with other sequences of E. coli strains, may help to reveal the bacteriophage resistance mechanism of E. coli.
