Haplotype-Resolved Genome Assemblies of Deep-Sea Annelid Lindaspio polybranchiata Published
Researchers have published haplotype-resolved, chromosome-level genome assemblies for Lindaspio polybranchiata, a deep-sea spionid annelid and early colonizer of cold seep ecosystems. Published in Scientific Data, this study addresses the limited genomic resources previously available for this genus. The team utilized PacBio HiFi, Illumina, Hi-C, and RNA-seq data to generate phased assemblies for two haplotypes, A and B. Haplotype A features a genome size of 1.72 Gb with 81.5% of sequences anchored to 18 pseudochromosomes, while Haplotype B has a size of 1.38 Gb with 92.8% anchored. BUSCO completeness scores reached 91.2% and 91.7% respectively. The study predicted over 22,000 protein-coding genes in Haplotype A and nearly 19,600 in Haplotype B, with high functional annotation rates. These comprehensive genomic resources provide a critical foundation for future research into chromosome organization, comparative genomics, deep-sea adaptation mechanisms, and the evolutionary history of Lindaspio and related spionid annelids, marking a significant advancement in marine biological sciences.
