A chromosome-level genome assembly of the classical model nematode Panagrellus redivivus for comparative studies of parasitism evolution

Researchers used Oxford Nanopore long reads, Illumina short reads, and Hi-C to build a chromosome-level genome assembly of the classical model nematode Panagrellus redivivus. The assembly comprises five chromosome-scale scaffolds, with 97.1% BUSCO completeness and 17,839 predicted protein-coding genes. Comparative orthology analysis shows extensive ortholog sharing with Clade IV parasitic nematodes, providing a key non-parasitic reference genome for studying the evolution of parasitism, ovoviviparity, and gene family dynamics.
