Yunfei Guo, from the University of Southern California, presents his ASHG 2015 poster on a de novo assembly of a diploid Asian genome. The uniform coverage of long-read sequencing helped access regions previously unresolvable due to high GC bias or long repeats. The assembly allowed scientists to fill some 400 gaps in the latest human reference genome, including some as long as 50 kb.
Ilyonectria mors-panacis is a serious disease hampering the production of Panax notoginseng, an important Chinese medicinal herb, widely used for its anti-inflammatory, anti-fatigue, hepato-protective, and coronary heart disease prevention effects. Here, we report the first Illumina-Pacbio hybrid sequenced draft genome assembly of I. mors-panacis strain G3B and its annotation. The availability of this genome sequence not only represents an important tool toward understanding the genetics behind the infection mechanism of I. mors-panacis strain G3B but also will help illuminate the complexities of the taxonomy of this species.
Puccinia novopanici is an important biotrophic fungal pathogen that causes rust disease in switchgrass. Lack of genomic resources for P. novopanici has hampered the progress towards developing effective disease resistance against this pathogen. Therefore, we have sequenced the whole genome of P. novopanici and generated a framework to understand pathogenicity mechanisms, identify effectors, repeat element invasion, genome evolution, and comparative genomics among Puccinia species in the future. Long and short read sequences were generated from P. novopanici genomic DNA by PacBio and Illumina technologies, respectively, and assembled a 99.9 megabase (Mb) genome. Transcripts of P. novopanici were predicted from assembled…
We present a high-quality draft genome assembly for Fusarium oxysporum f. sp. cubense tropical race 4 (Fusarium odoratissimum), assembled from PacBio reads and consisting of 15 contigs with a total assembly size of 48.59?Mb. This strain appears to belong to vegetative compatibility group complex 01213/16.Copyright © 2019 Warmington et al.
Shiga toxin-producing Escherichia coli O157:H7 is a foodborne pathogen and is responsible for outbreaks of human gastroenteritis. This report documents the draft genome sequences of nine O157:H7 cattle strains, which were identified to be PCR positive for a Shiga toxin gene but displayed different levels of functional toxin activity.
Kodamaea ohmeri is a symbiont of the small hive beetle (SHB), which is a scavenger of honey bee colonies. The SHB causes absconding of the economically important honey bee (Apis mellifera) and deposits K. ohmeri in the honeycomb. We describe long-read sequencing and further analyses of the K. ohmeri genome.
We report the draft whole-genome sequence of Alteromonas sp. strain RKMC-009, which was isolated in situ from the sponge Xestospongia muta in San Salvador, The Bahamas, using an isolation chip (ichip). Automated biosynthetic gene cluster analysis using antiSMASH 4.0 predicted the presence of 22 biosynthetic gene clusters.Copyright © 2019 MacIntyre et al.
Here, we report the draft genome sequence of Mesosutterella multiformis JCM 32464T, a new member of the family Sutterellaceae that was isolated from human feces. The genome assembly comprised 2,621,983?bp, with a G+C content of 56.9%. This genomic analysis will be useful for understanding the metabolic activities of this asaccharolytic bacterium.Copyright © 2019 Ikeyama et al.
The first draft genome sequence of the pearl millet blast pathogen Magnaporthe grisea PMg_Dl from India is presented. The genome information of M. grisea will be useful to understand the Magnaporthe speciation, genetic diversity, environmental adaptation, and pathogenic and host range determinants.Copyright © 2019 Prakash et al.
The fungus Amphirosellinia nigrospora strain JS-1675 has been reported to exert antimicrobial effects against various plant-pathogenic bacteria and fungi. Here, we report the draft genome sequence of A. nigrospora for the first time. The assembly comprises 48,177,783?bp with 18 scaffolds.Copyright © 2019 Jeon et al.
The type VI secretion system (T6SS) facilitates lethal competition between bacteria through direct contact. Comparative genomics has facilitated the study of these systems in Vibrio fischeri, which colonizes the squid host Euprymna scolopes Here, we report the draft genome sequences of two lethal V. fischeri strains that encode the T6SS, FQ-A001 and ES401.Copyright © 2019 Bultman et al.
We present here the first draft genome sequence of Leishmania (Viannia) lainsoni strain 216-34, sequenced using PacBio and MiSeq platforms. PacBio contigs were generated from de novo assemblies using CANU version 1.6 and polished using Illumina reads.
Streptomyces sp. strain Z26 exhibited antifungal activity and turned out to be a producer of the secondary metabolites novonestmycin A and B. The 6.5-Mb draft genome gives insight into the complete secondary metabolite production capacity and builds the basis to find and locate the biosynthetic gene cluster encoding the novonestmycins.
We report here the draft genome of Saitozyma podzolica DSM 27192 sequenced based on PacBio chemistry. This yeast isolate produces large amounts of single-cell oil (SCO) and gluconic acid (GA). Information from the genome sequence will provide additional insight into the genetic mechanism of SCO and GA metabolism in this organism.
Sinorhizobium meliloti is a Gram-negative bacterium which fixes atmospheric nitrogen in symbiosis with Medicago spp. We report the draft genome sequence of S. meliloti strain CXM1-105, associated with nodules of Medicago sativa subsp. varia (Martyn) Arcang.
