Chromosome-level genome assembly of the model nematode Panagrellus redivivus published
Start here
Researchers have produced a chromosome-level genome assembly of Panagrellus redivivus, a classical non-parasitic model nematode, combining Oxford Nanopore long reads, Illumina short reads, and Hi-C data. The assembly resolves into five chromosome-scale scaffolds, with 97.1% BUSCO completeness and 17,839 predicted protein-coding genes. Comparative orthology analysis reveals extensive orthogroup sharing with Clade IV parasitic nematodes, making the new sequence a key non-parasitic reference genome. The resource is intended to support studies of parasitism evolution, ovoviviparity, and gene family dynamics. The work has appeared as a preprint, and peer review and further comparative analyses using this reference are still to come.
