Assembling microbial genomes using long nanopore sequencing reads
In order to understand the true diversity and functions of microorganisms, producing fully annotated, complete genomes is essential. However, 90% of bacterial genomes are predicted to be incomplete.
Compared to short-read sequencing data, long nanopore sequencing reads simplify genome assembly, with the ability to span repeat-rich sequences (characteristic of antimicrobial resistance genes) and structural variants. Nanopore sequencing also shows a lack of bias in GC-rich regions, in contrast to other sequencing platforms, further supporting the assembly of complete genomes.
Here we present a simple workﬂow for bacterial genome assembly from a single-organism culture, using MinION™ Flow Cells on MinION or GridION™ sequencing devices.
