At the National Center for Genome Resources in Santa Fe, New Mexico, scientists run a world- renowned sequencing service facility that’s heavy on long reads and bioinformatics expertise. It also supports a wide range of microbial, plant, and animal projects.
Arthropod Mycoplasma are little known endosymbionts in insects, primarily known as plant disease vectors. Mycoplasma in other arthropods such as arachnids are unknown. We report the first complete Mycoplasma genome sequenced, identified, and annotated from a scorpion, Centruroides vittatus, and designate it as Mycoplasma vittatus We find the genome is at least a 683,827 bp single circular chromosome with a GC content of 42.7% and with 987 protein-coding genes. The putative virulence determinants include 11 genes associated with the virulence operon associated with protein synthesis or DNA transcription and ten genes with antibiotic and toxic compound resistance. Comparative analysis revealed…
Heterodera glycines, commonly referred to as the soybean cyst nematode (SCN), is an obligatory and sedentary plant parasite that causes over a billion-dollar yield loss to soybean production annually. Although there are genetic determinants that render soybean plants resistant to certain nematode genotypes, resistant soybean cultivars are increasingly ineffective because their multi-year usage has selected for virulent H. glycines populations. The parasitic success of H. glycines relies on the comprehensive re-engineering of an infection site into a syncytium, as well as the long-term suppression of host defense to ensure syncytial viability. At the forefront of these complex molecular interactions are…
Enterococcus durans Oregon-R-modENCODE strain BDGP3 was isolated from the Drosophila melanogaster gut for functional host-microbe interaction studies. The complete genome is composed of a single circular genome of 2,983,334 bp, with a G+C content of 38%, and a single plasmid of 5,594 bp. Copyright © 2017 Wan et al.
Pyrenophora teres f.teres, the causal agent of net form net blotch (NFNB) of barley, is a destructive pathogen in barley-growing regions throughout the world. Typical yield losses due to NFNB range from 10 to 40%; however, complete loss has been observed on highly susceptible barley lines where environmental conditions favor the pathogen. Currently, genomic resources for this economically important pathogen are limited to a fragmented draft genome assembly and annotation, with limited RNA support of theP. teresf.teresisolate 0-1. This research presents an updated 0-1 reference assembly facilitated by long-read sequencing and scaffolding with the assistance of genetic linkage maps. Additionally,…
Here, we report the high-quality draft genome sequence of actinobacterium Kibdelosporangium sp. MJ126-NF4, producer of the type II polyketide azicemicins, obtained using Illumina and PacBio sequencing technologies. The 11.75-Mbp genome contains >11,000 genes and 22 polyketide and nonribosomal peptide natural product gene clusters. Copyright © 2015 Ogasawara et al.
Presented here is the first completely assembled genome sequence of Kocuria palustris, an actinobacterial species with broad ecological distribution. The single, circular chromosome of K. palustris MU14/1 comprises 2,854,447 bp, has a G+C content of 70.5%, and contains a deduced gene set of 2,521 coding sequences.

Viruses are major pathogens in all biological systems. Virus propagation and downstream analysis remains a challenge, particularly in the ocean where the majority of their microbial hosts remain recalcitrant to current culturing techniques. We used a cultivation-independent approach to isolate and sequence individual viruses. The protocol uses high-speed fluorescence-activated virus sorting flow cytometry, multiple displacement amplification (MDA), and downstream genomic sequencing. We focused on ‘giant viruses’ that are readily distinguishable by flow cytometry. From a single-milliliter sample of seawater collected from off the dock at Boothbay Harbor, ME, USA, we sorted almost 700 single virus particles, and subsequently focused on…
Acetobacter pomorum Oregon-R-modENCODE strain BDGP5 was isolated from Drosophila melanogaster for functional host-microbe interaction studies. The complete genome is composed of a single chromosomal circle of 2,848,089 bp, with a G+C content of 53% and three plasmids of 131,455 bp, 19,216 bp, and 9,160 bp. Copyright © 2017 Wan et al.
Rhodococcus fascians, a phytopathogen that alters plant development, inflicts significant losses in plant production around the world. We report here the complete genome sequence of R. fascians D188, a well-characterized model isolate, and Rhodococcus species PBTS (pistachio bushy top syndrome) 1 and 2, which were shown to be responsible for a disease outbreak in pistachios.
