Hybrid Genome Sequencing

Unifying Technologies for Deeper Genomic Clarity

Introduction and Workflow

  • Hybrid sequencing integrates the accuracy of short-read sequencing (Illumina) with the comprehensive coverage of long-read sequencing (PacBio or Nanopore), ensuring detailed and complete genome assemblies.
  • This approach involves sequencing the same sample with both technologies, which means different libraries are prepared for both the technology followed by sequencing.
  • Following sequencing, advanced bioinformatics tools are used to align and integrate the long and short reads, enhancing variant detection and improving the resolution of complex genomic regions.
  • Hybrid sequencing is applicable to a wide range of research areas, from complex genome assemblies to resolving repetitive regions and improving the quality of reference genomes.

Advantage

  • Combines long-read and short-read sequencing for more complete and accurate genome assemblies, effectively resolving complex regions and reducing gaps.
  • Balances the cost efficiency of short-read sequencing with the detailed resolution of long-read sequencing, making it a budget-friendly choice for comprehensive genome analysis.
  • Enhances detection of structural variants, such as large insertions and deletions, improving the understanding of genetic diversity and disease mechanisms.
  • Provides better coverage of challenging genomic features, like high GC content and repetitive sequences, by leveraging the strengths of both sequencing technologies.

Applications of Hybrid Genome Sequencing

  • Comprehensive Genome Mapping- Hybrid genome sequencing is used to create detailed genome maps by combining the strengths of both short-read and long-read technologies, leading to more complete and accurate assemblies of complex genomes.
  • Structural Variant Detection- This approach is effective in identifying structural variants, such as large deletions, duplications, and insertions, which are often challenging to detect with short-read sequencing alone.
  • Genetic Diversity and Evolutionary Studies- It facilitates the study of genetic diversity and evolutionary processes by providing high-resolution data on genomic variations across different species and populations.
