With PacBio long-read sequencing, scientists are making exciting new discoveries about the microbes that live around and within us. From viruses to bacteria to fungi, SMRT Sequencing is shedding light on how these organisms function and evolve.
At Cold Spring Harbor Laboratory, scientists used SMRT Sequencing to decode one of the most challenging cancer genomes ever encountered. Along the way, they built a portfolio of open-access analysis tools that will help researchers everywhere make structural variation discoveries with long-read sequencing data.
Scientists at the USDA and Cold Spring Harbor Laboratory know that better breeding of maize to feed a growing population will depend on an accurate reference assembly. They tackled the previously intractable crop with a combination of PacBio Sequencing and BioNano Genomics® genome maps, leading to the first-ever high-quality reference assembly.
Scientists are utilizing long-read PacBio sequencing to provide uniquely comprehensive views of complex plant and animal genomes. These efforts are uncovering novel biological mechanisms, enabling progress in crop development, and much more. To date, scientists have published over 1000 papers with Single Molecule, Real-Time (SMRT) Sequencing, many covering breakthroughs in the plant and animal sciences. In this case study, we look at examples in model organisms Drosophila and C. elegans and non-model organisms coffee, Oropeitum, danshen, and sugarbeet, where SMRT Sequencing has contributed to a more accurate understanding of biology. These efforts underscore the broad applicability of long-read sequencing in…
Scientists from WashU, Macrogen, and Mount Sinai are using long-read sequencing with single-molecule, next-generation genome mapping to create gold-quality de novo assemblies of human genomes. Unbiased de novo assembled genomes also highlight the substantial amount of structural variation unique to individuals and populations, which cannot be accessed by short-read technologies that use a reference-based re-sequencing approach.
From crop improvement to breeding healthier livestock to modeling human disease, scientists are using PacBio Sequencing to advance understanding of plant and animal genomes. In this article, we look at four examples of plant and animal genome references improved or made possible with SMRT Sequencing, including an early example of transcriptome sequencing of a chicken for improved annotation. These examples highlight insights gained with SMRT Sequencing that are missed with short-read data, such as complex regions or novel genes.
Scientists at the Gladstone Institutes were early adopters of SMRT Sequencing for transcriptome studies. In a recent study, they used full-length isoform sequence data to overhaul the annotation of the chicken genome, thus providing heart biology researchers with a valuable new reference tool for future studies.
At KeyGene, agricultural specialists strive to improve plant varieties through molecular breeding and other advances. They rely on SMRT Sequencing to produce top-notch assemblies from even the most difficult genomes.
In an interview with Theral Timpson part of Mendelspods series on long-read sequencing Ulf Gyllensten, a professor in Medical Molecular Genetics at Uppsala University, spoke about using PacBio technology for HLA typing, human genome studies, transcriptomics, and more.
Genomics luminary Mike Snyder, Profesor and Chair of the Genetics Department at Stanford University and Director of the Stanford Center for Genomics and Personalized Medicine, has been making strides in gene expression studies for years. His latest advance: analyzing whole human transcriptomes, which he calls personal transcriptomes, to better understand gene activity in an individual. Snyder says this approach could one day become a crucial element in clinical care. Dr. Snyder has published recent papers in Nature Biotechnology and PNAS using Single Molecule, Real- Time (SMRT) Sequencing for transcriptome analysis and demonstrated that long reads enable full coverage of RNA molecules. Recently he talked…
Dan Geraghty, a researcher at Fred Hutchinson Cancer Research Center and CEO of Scisco Genetics, has spent much of his career focused on the genetics of immune response. Recently he talked to Mendelspod host Theral Timpson as part of a series of podcasts on the rise of long-read sequencing.
Scientists at UC Davis School of Medicine have used the PacBio RS to sequence a previously unsequenceable region of highly repetitive DNA on the X chromosome. Their research has provided a critical leap forward in understanding the genetic complexity of repeat expansion disorders such as Fragile X Syndrome. The new method provides a path towards the first accurate means of population screening for Fragile X Syndrome, which is the most common cause of inherited intellectual disability and the most common known genetic cause of autism.
At the Icahn Institute for Genomics and Multiscale Biology, scientists use automated DNA sizing together with long- read sequencing to analyze human samples, conduct routine surveillance on microbes, and more.
Extraordinarily long sequencing reads and recent throughput advances are allowing scientists to affordably assemble and close larger genomes, including many plants and animals even resolving complex repeats or extreme GC regions.
Scientists at the University of Oslos Centre for Ecological and Evolutionary Synthesis (CEES) applied long PacBio reads to a genome that was proving particularly difficult to assemble. Today, sequencing problems associated with the Atlantic cod genome are a thing of the past and researchers are using their new assembly as the foundation for a major resequencing effort thats just getting started.
