Case Study: Pioneering a pan-genome reference collection

At DuPont Pioneer, DNA sequencing is paramount for R&D to reveal the genetic basis for traits of interest in commercial crops such as maize, soybean, sorghum, sunflower, alfalfa, canola, wheat, rice, and others. They cannot afford to wait the years it has historically taken for high-quality reference genomes to be produced. Nor can they rely on a single reference to represent the genetic diversity in its germplasm.

Webinar: Opportunities for using PacBio Long-read sequencing for COVID-19 research

In this Labroots webinar, Meredith Ashby, Director of Microbial Genomics at PacBio, describes the utility of highly accurate long-read sequencing, known as HiFi sequencing, to understand the SARs-CoV-2 viral genome. HiFi sequencing enables mutation phasing and rare variant detection to understand viral stability and mutation rates, as well as providing insights into viral population structure for monitoring viral evolution. Ashby also shares how HiFi sequencing can be used to explore the host immune response to COVID-19, specifically by providing full-length sequencing of the B cell repertoire, IGH locus and HLA genes.

Complete resequencing of extended genomic regions using fosmid target capture and single molecule real-time (SMRT) long read sequencing technology.

A longstanding goal of genomic analysis is the identification of causal genetic factors contributing to disease. While the common disease/common variant hypothesis has been tested in many genome-wide association studies, few advancements in identifying causal variation have been realized, and instead recent findings point away from common variants towards aggregate rare variants as causal. A challenge is obtaining complete phased genomic sequences over extended genomic regions from sufficient numbers of cases and controls to identify all potential variation causal of a disease. To address this, we modified methods for targeted DNA isolation using fosmid technology and single-molecule, long-sequence-read generaton that…

Targeted sequencing of genes from soybean using NimbleGen SeqCap EZ and PacBio SMRT Sequencing

Full-length gene capture solutions offer opportunities to screen and characterize structural variations and genetic diversity to understand key traits in plants and animals. Through a combined Roche NimbleGen probe capture and SMRT Sequencing strategy, we demonstrate the capability to resolve complex gene structures often observed in plant defense and developmental genes spanning multiple kilobases. The custom panel includes members of the WRKY plant-defense-signaling family, members of the NB-LRR disease-resistance family, and developmental genes important for flowering. The presence of repetitive structures and low-complexity regions makes short-read sequencing of these genes difficult, yet this approach allows researchers to obtain complete sequences…

Immune regions are no longer incomprehensible with SMRT Sequencing

The complex immune regions of the genome, including MHC and KIR, contain large copy number variants (CNVs), a high density of genes, hyper-polymorphic gene alleles, and conserved extended haplotypes (CEH) with enormous linkage disequilibrium (LDs). This level of complexity and inherent biases of short-read sequencing make it challenging for extracting immune region haplotype information from reference-reliant, shotgun sequencing and GWAS methods. As NGS based genome and exome sequencing and SNP arrays have become a routine for population studies, numerous efforts are being made for developing software to extract and or impute the immune gene information from these datasets. Despite these…

Multiplex target enrichment using barcoded multi-kilobase fragments and probe-based capture technologies

Target enrichment capture methods allow scientists to rapidly interrogate important genomic regions of interest for variant discovery, including SNPs, gene isoforms, and structural variation. Custom targeted sequencing panels are important for characterizing heterogeneous, complex diseases and uncovering the genetic basis of inherited traits with more uniform coverage when compared to PCR-based strategies. With the increasing availability of high-quality reference genomes, customized gene panels are readily designed with high specificity to capture genomic regions of interest, thus enabling scientists to expand their research scope from a single individual to larger cohort studies or population-wide investigations. Coupled with PacBio® long-read sequencing, these…

Characterization of the Poly-T variants in the TOMM40 gene using PacBio long reads

Genes associated with several neurological disorders have been shown to be highly polymorphic. Targeted sequencing of these genes using NGS technologies is a powerful way to increase the cost-effectiveness of variant discovery and detection. However, for a comprehensive view of these target genes, it is necessary to have complete and uniform coverage across regions of interest. Unfortunately, short-read sequencing technologies are not ideal for these types of studies as they are prone to mis-mapping and often fail to span repetitive regions. Targeted sequencing with PacBio long reads provides the unique advantage of single-molecule observations of complex genomic regions. PacBio long…

Target enrichment using a neurology panel for 12 barcoded genomic DNA samples on the PacBio SMRT Sequencing platform

Target enrichment is a powerful tool for studies involved in understanding polymorphic SNPs with phasing, tandem repeats, and structural variations. With increasing availability of reference genomes, researchers can easily design a cost-effective targeted investigation with custom probes specific to regions of interest. Using PacBio long-read technology in conjunction with probe capture, we were able to sequence multi-kilobase enriched regions to fully investigate intronic and exonic regions, distinguish haplotypes, and characterize structural variations. Furthermore, we demonstrate this approach is advantageous for studying complex genomic regions previously inaccessible through other sequencing platforms. In the present work, 12 barcoded genomic DNA (gDNA) samples…

Defining transgene insertion sites and off-target effects of homology-based gene silencing informs the use of functional genomics tools in Phytophthora infestans.

DNA transformation and homology-based transcriptional silencing are frequently used to assess gene function in Phytophthora. Since unplanned side-effects of these tools are not well-characterized, we used P. infestans to study plasmid integration sites and whether knockdowns caused by homology-dependent silencing spreads to other genes. Insertions occurred both in gene-dense and gene-sparse regions but disproportionately near the 5′ ends of genes, which disrupted native coding sequences. Microhomology at the recombination site between plasmid and chromosome was common. Studies of transformants silenced for twelve different gene targets indicated that neighbors within 500-nt were often co-silenced, regardless of whether hairpin or sense constructs…
