A hybrid sequence assembly of the complete Mycoplasma synoviae type strain WVU 1853T genome was compared to that of strain MS53. The findings support prior conclusions about M. synoviae, based on the genome of that otherwise uncharacterized field strain, and provide the first evidence of epigenetic modifications in M. synoviae.

A Gram-negative, non-motile and short-rod shaped and gamma-radiation-resistant bacterium Deinococcus soli N5(T), isolated from a rice field soil in South Korea. The complete genome of D. soli N5(T) consists of a chromosome (3,236,984bp). The key enzymes for the central DNA repair mechanisms were present in the genome. The enzyme coding genes has been identified which is involving in the nucleotide excision repair (NER) pathway. The gene cluster in the genome sequence suggest that the D. soli N5(T) use (NER) pathways for efficient removal of pyrimidine dimers that are the most abundant type of UV- induced damage.

Pseudomonas aeruginosa is a group of bacteria, which can be isolated from diverse ecological niches. P. aeruginosa strain F9676 was first isolated from a rice seed sample in 2003. It showed strong antagonism against several plant pathogens. In this study, whole genome sequencing was carried out. The total genome size of F9676 is 6368,008bp with 5586 coding genes (CDS), 67 tRNAs and 3 rRNAs. The genome sequence of F9676 may shed a light on antagonism P. aeruginosa.

We present here the complete genome sequence of a strain of enteroinvasive Escherichia coli O96:H19 from a severe foodborne outbreak in a canteen in Italy in 2014. The complete genome may provide important information about the acquired pathogenicity of this strain and the transition between commensal and pathogenic E. coli. Copyright © 2015 Pettengill et al.
Pineapple (Ananas comosus var. comosus) is known as the king of fruits for its crown and is the third most important tropical fruit after banana and citrus. The plant, which is indigenous to South America, is the most important species in the Bromeliaceae family and is largely traded for fresh fruit consumption. Here, we report the complete chloroplast sequence of the MD-2 pineapple that was sequenced using the PacBio sequencing technology.In this study, the high error rate of PacBio long sequence reads of A. comosus’s total genomic DNA were improved by leveraging on the high accuracy but short Illumina reads for error-correction via the latest error correction module from Novocraft. Error corrected long PacBio reads were assembled by using a single tool to produce a contig representing the pineapple chloroplast genome. The genome of 159,636 bp in length is featured with the conserved quadripartite structure of chloroplast containing a large single copy region (LSC) with a size of 87,482 bp, a small single copy region (SSC) with a size of 18,622 bp and two inverted repeat regions (IRA and IRB) each with the size of 26,766 bp. Overall, the genome contained 117 unique coding regions and 30 were repeated in the IR region with its genes contents, structure and arrangement similar to its sister taxon, Typha latifolia. A total of 35 repeats structure were detected in both the coding and non-coding regions with a majority being tandem repeats. In addition, 205 SSRs were detected in the genome with six protein-coding genes contained more than two SSRs. Comparative chloroplast genomes from the subclass Commelinidae revealed a conservative protein coding gene albeit located in a highly divergence region. Analysis of selection pressure on protein-coding genes using Ka/Ks ratio showed significant positive selection exerted on the rps7 gene of the pineapple chloroplast with P less than 0.05. Phylogenetic analysis confirmed the recent taxonomical relation among the member of commelinids which support the monophyly relationship between Arecales and Dasypogonaceae and between Zingiberales to the Poales, which includes the A. comosus.The complete sequence of the chloroplast of pineapple provides insights to the divergence of genic chloroplast sequences from the members of the subclass Commelinidae. The complete pineapple chloroplast will serve as a reference for in-depth taxonomical studies in the Bromeliaceae family when more species under the family are sequenced in the future. The genetic sequence information will also make feasible other molecular applications of the pineapple chloroplast for plant genetic improvement.
Clostridium difficile contains many integrated and extrachromosomal genetic elements. In this study, we determined, annotated, and analyzed the complete genome of the C. difficile bacteriophage phiCDIF1296T using single-molecule real-time sequencing technology. To our knowledge, this represents the largest genome (131 kb) of a temperate C. difficile phage recognized so far. Copyright © 2015 Wittmann et al.
