These include the identification of many false gene duplications, increases in gene sizes, chromosome rearrangements that are specific to lineages, a repeated independent chromosome breakpoint in bat genomes, and a canonical GC-rich pattern in protein-coding genes and their regulatory regions. Our assemblies correct substantial errors, add missing sequence in some of the best historical reference genomes, and reveal biological discoveries. We confirm that long-read sequencing technologies are essential for maximizing genome quality, and that unresolved complex repeats and haplotype heterozygosity are major sources of assembly error when not handled correctly.

Here we present lessons learned from generating assemblies for 16 species that represent six major vertebrate lineages. To address this issue, the international Genome 10K (G10K) consortium 5, 6 has worked over a five-year period to evaluate and develop cost-effective methods for assembling highly accurate and nearly complete reference genomes. However, such assemblies are available for only a few non-microbial species 1, 2, 3, 4. High-quality and complete reference genome assemblies are fundamental for the application of genomics to biology, disease, and biodiversity conservation.
