Salmonella enterica subsp. enterica serovar Dublin is a host-adapted pathogen for cattle that can cause invasive disease in humans. To facilitate genomic comparisons characterizing virulence determinants of this pathogen, we present the complete genome sequences of three S. Dublin strains isolated from bovine sources at harvest.
Streptococcus thermophilus is one of the most used dairy starters for the production of yogurt and cheese. We report here the complete genome sequence of the industrial strain S. thermophilus N4L, which is used in dairy technology for its fast-acidifying phenotype.
Hypericum perforatum is a widely known medicinal herb used mostly as a remedy for depression because of its abundant secondary metabolites. Quantitative real-time PCR (qRT-PCR) is an optimized method for the efficient and reliable quantification of gene expression studies. In general, reference genes are used in qRT-PCR analysis because of their known or suspected housekeeping roles. However, their expression level cannot be assumed to remain stable under all possible experimental conditions. Thus, the identification of high quality reference genes is very necessary for the interpretation of qRT-PCR data. In this study, we investigated the expression of fourteen candidate genes, including…
Long-read sequencing has greatly contributed to the generation of high quality assemblies, albeit at a high cost. It is also not always clear how to combine sequencing platforms. We sequenced the genome of the olive fruit fly (Bactrocera oleae), the most important pest in the olive fruits agribusiness industry, using Illumina short-reads, mate-pairs, 10x Genomics linked-reads, Pacific Biosciences (PacBio), and Oxford Nanopore Technologies (ONT). The 10x linked-reads assembly gave the most contiguous assembly with an N50 of 2.16 Mb. Scaffolding the linked-reads assembly using long-reads from ONT gave a more contiguous assembly with scaffold N50 of 4.59 Mb. We also…
High-quality genomic DNA extraction is a starting point for many downstream applications in modern molecular biology. Here, we describe a simple method for isolating high molecular weight genomic DNA from planarians. The method is based on tissue lysis by a mixture of a chaotropic salt and detergent followed by organic extraction to remove proteins and lipids followed by a postpurification step to remove contaminating polysaccharides. The isolated DNA is of high molecular weight and compatible with polymerase chain reaction, cloning, or next-generation sequencing library preparation.
Water supply is essential for maintaining normal physiological function during the rapid growth of bamboo. Aquaporins (AQPs) play crucial roles in water transport for plant growth and development. Although 26 PeAQPs in bamboo have been reported, the aquaporin-led mechanism of maintaining diurnal water balance in bamboo shoots remains unclear. In this study, a total of 63 PeAQPs were identified, based on the updated genome of moso bamboo (Phyllostachys edulis), including 22 PePIPs, 20 PeTIPs, 17 PeNIPs, and 4 PeSIPs. All of the PeAQPs were differently expressed in 26 different tissues of moso bamboo, based on RNA sequencing (RNA-seq) data. The…
The main challenge in assembling plant genome is its ploidy level, repeats content, and polymorphism. The second-generation sequencing delivered the throughput and the accuracy that is crucial to whole-genome sequencing but insufficient and remained challenging for some plant species. It is known that genomes produced by next-gen- eration sequencing produced small contigs that would inflate the number of annotated genes (Varshney et al. 2011) and missed on the transposable elements that are abun- dant in plant genome due to their repetitive nature (Michael and Jackson 2013).
The full genome sequence of Bacillus safensis KCTC 12796BP which had been isolated from the marine sponge in the seawater of Jeju Island, was determined by Pac-Bio next- generation sequencing system. A circular chromosome in the length of 3,935,874 bp was obtained in addition to a circular form of plasmid having 36,690 bp. The G + C content of chromosome was 41.4%, and that of plasmid was 37.3%. The number of deduced CDSs in the chromosome was 3,980, whereas 36 CDS regions were determined in a plasmid. Among the deduced CDSs in chromosome, 81 tRNA genes and 24 rRNA genes…
This tutorial provides a high-level overview of the features contained within the SMRT Link software. SMRT Link is the web-based end-to-end software workflow manager for run design and set-up on the Sequel System, Data Management, and SMRT Analysis.
This tutorial provides an overview of the Circular Consensus Sequence (CCS) analysis application. The CCS algorithm is used in applications that require distinguishing closely related DNA molecules in the same sample. Applications of CCS include profiling microbial communities, resolving viral populations and accurately identifying somatic variations within heterogeneous tumor cells.
This tutorial provides an overview of the Long Amplicon Analysis (LAA) application. The LAA algorithm generates highly accurate, phased and full-length consensus sequences from long amplicons. Applications of LAA include HLA typing, alternative haplotyping, and localized de novo assemblies of targeted genes.
This tutorial provides an overview of the Isoform Sequencing (Iso-Seq) analysis application. The Iso-Seq application provides reads that span entire transcript isoforms, from the 5′ end to the 3′ polyA-tail. Generation of accurate, full-length transcript sequences greatly simplifies analysis by eliminating the need for transcript reconstruction to infer isoforms using error-prone assembly of short RNA-seq reads.
This tutorial provides an overview of the Hierarchical Genome Assembly Process (HGAP4) de novo assembly analysis application. HGAP4 generates accurate de novo assemblies using only PacBio data. HGAP4 is suitable for assembling a wide range of genome sizes and complexity. HGAP4 now includes some support for diploid-aware assembly.
