De novo sequencing refers to sequencing a novel genome where there is no reference sequence available for alignment. Sequence reads are assembled as contigs, and the coverage quality of de novo sequence data depends on the size and continuity of the contigs (ie, the number of gaps in the data).
Next-generation sequencing (NGS) allows faster, more accurate characterization of any species compared to traditional methods, such as Sanger sequencing. Illumina NGS technology offers rapid, comprehensive, accurate characterization of any species.
When sequencing a genome for the first time, a combined approach can yield higher-quality assemblies. For example, combining short-insert, paired-end and long-insert, mate pair sequences is one option to maximize coverage. The short reads, sequenced at higher depths, can fill in gaps not covered by the long inserts.
This combination enables detection of a broad range of structural variant types and is essential for accurate identification of complex rearrangements.
