We present a genome assembly from an individual Acholoe squamosa (the star-devouring scaleworm; Annelida; Polychaeta; Phyllodocida; Polynoidae). The sequence is 1,481.5 megabases in span. Most of the scaffolded into 18 chromosomal pseudomolecules. mitochondrial has also been assembled and 15.64 kilobases length.

Abstract The organization of genomes into chromosomes is critical for processes such as genetic recombination, environmental adaptation, and speciation. All animals with bilateral symmetry inherited a genome structure from their last common ancestor that has been highly conserved in some taxa but seemingly unconstrained others. However, the evolutionary forces driving these differences by which they emerge have remained largely uncharacterized. Here, we analyze across phylum Annelida using 23 chromosome-level annelid genomes. We find while many lineages maintained bilaterian structure, Clitellata, group containing leeches earthworms, possesses completely scrambled develop rearrangement index to quantify extent evolution show that, compared bilaterians, earthworms among most rearranged any currently sampled species. further can be classified two distinct categories—high low rearrangement—largely influenced presence or absence, respectively, chromosome fission events. Our findings demonstrate animal variable within reveal occur both gradual, stepwise fashion, rapid, all-encompassing changes over short timescales.

Lindaspio polybranchiata, a member of the Spionidae family, has been reported at Lingshui Cold Seep, where it formed dense population around this nascent methane vent. We sequenced and assembled genome L. polybranchiata performed comparative genomic analyses to investigate genetic basis adaptation deep sea. Supporting this, transcriptomic fatty acid data further corroborate our findings. report first deep-sea spionid, polybranchiata. Over long-term adaptive evolution, genes associated with vision biological rhythmicity were lost, which may indirectly benefit oligotrophy by eliminating energetically costly processes. Compared its shallow-sea relatives, significantly higher proportion polyunsaturated acids (PUFAs) expanded gene families involved in biosynthesis unsaturated chromatin stabilization, possibly response high hydrostatic pressure. Additionally, broad digestive scope, allowing fully utilize limited food resources sea sustain large population. As pioneer species, an repertoire encoding potential chemoreceptor proteins, including ionotropic receptors (IRs) gustatory receptor-like (GRLs). These characterized their conserved 3D structures, enhance organism's ability detect chemical cues chemosynthetic ecosystems, facilitating rapid settlement suitable environments. Our results shed light on darkness, pressure, deprivation sea, providing insights into molecular for becoming species.
