Ancestral Origin and Structural Characteristics of Non-Syntenic Homologous Chromosomes in Abalones (Haliotis).

ABSTRACT: Structural variation is increasingly recognised as a pivotal contributor to genomic diversity in marine invertebrates, yet its extent and evolutionary significance remain poorly characterised in many species. Haplotype-phased genome assembly is an excellent resource for studying such variations by comparing homologous chromosomes. Here, we focus on abalones (genus Haliotis) that are iconic marine invertebrates originated in the Cretaceous period. They have long drawn attention for their ecological roles, distinctive morphology and cultural and economic value. In this study, we constructed a haplotype-phased genome assembly for the western Pacific abalone, Haliotis gigantea, using high-fidelity (HiFi) long-read sequencing and high-resolution chromosome conformation capture (Hi-C) data.
