Although it was the first polychaete genome sequenced, the original assembly is outdated by modern standards. Here, we combine long-read and short-read sequencing with Hi-C chromatin conformation capture to assemble chromosome-level nuclear and mitochondrial genomes of the laboratory strain of C. teleta. This reference assembly accurately reflects the expected genome size (∼243.6 Mb) and contains a highly complete, evolutionarily conserved gene repertoire. Notably, the nuclear and mitochondrial genomes are heavily rearranged, indicating a decoupling between gene family repertoire and chromosomal evolution. The analyses of developmental time courses of bulk and single-cell RNA-seq, ATAC-seq, and EM-seq data using the new reference assembly resulted in a significant improvement in quality, enabling the identification of new cell-type-specific gene markers. Finally, we generated a publicly available genome browser that ensures these resources comply with FAIR principles. Our study provides state-of-the-art genomic resources for C. teleta, addressing a pressing community need and opening new research opportunities in animal and genome evolution. |
