The nuclear genome spans 615.9 Mb, scaffolded into 50 pseudochromosomes and 115 smaller scaffolds, with high completeness (BUSCO score: 98.9%) that provides a decisive improvement over the previous assembly (537 Mb; 68,292 contigs; BUSCO 83.6%). Coverage differences in resequenced males and females allowed identification of the Z chromosome and several W-linked contigs. As expected from previous studies, we found that synteny was largely conserved with related Lepidoptera, although chromosomal fissions may explain the higher chromosome number of 49 autosomes compared to typical lepidopteran karyotypes. We also integrated into the assembly linkage map, allowing estimation of a genome-wide male recombination rate of 5.06 cM/Mb, varying from 11.6 cM/Mb to 1.98 cM/Mb from the smallest to the largest chromosomes. Repetitive elements represented 49.1% of this new assembly, dominated by LINEs (45.1% of classified repeats). Finally, gene prediction identified 12,898 gene models, among which 17 circadian rhythm genes were manually curated.

These include high quality chromosomal reference genome assemblies for Pacific marine and freshwater sticklebacks. However, these reference genomes may bias mapping of short-read data from Atlantic stickleback, and do not fully resolve some repeat-rich regions. Here, we present a chromosome-level reference genome (fGasAcu404) generated from an Atlantic anadromous stickleback using PacBio HiFi and Hi-C data.

Syntenic comparisons and mapping of short reads from well-studied spined and spineless stickleback indicate these loci are incorporated into the new assembly. We evaluate the utility of this reference for paleogenomic analyses by mapping ancient (>10,000 years BP) Norwegian stickleback DNA and assessing inversion karyotypes. We find marginal mapping gains and the ability to robustly infer homozygous ancestral karyotypes at three inversions in two ancient genomes which have predominantly marine-adaptive ancestry. However, karyotype is more ambiguous in an ancient genome with predominantly freshwater ancestry, reflecting the need for further genomic resources for this system.

Here, we provide an annotated, chromosome-level assembly of C. guttata derived from long- and ultra-long read data as an addition to the conservation genomics resources for the species.

The small snakehead (Channa asiatica), an important freshwater fish with significant commercial value, lacks the pelvic fins while some other fish species in the same genus have. To determine the genetic changes underlying the pelvic fin loss in the small snakehead, we assembled the chromosome-level genome of the species based on PacBio HiFi and Hi-C sequencing technology and performed comparative genomics analyses. The final genome assembly of the small snakehead has a total length of 714.57 Mb with 23 chromosomes (contig N50 of 27.93 Mb and scaffold N50 of 28.54 Mb), and 193.09 Mb (27.02%) interspersed repeats and 22,300 protein-coding genes were annotated. Phylogenetic and divergence analyses indicated that the small snakehead was the sister branch to the combination of the northern snakehead (C. argus) and the blotched snakehead (C. maculata) and diverged from the common ancestor approximately 24.7 Mya. Three small snakehead-specific missense mutations were identified in tbx4 gene whose loss could cause the pelvic fin loss. Significant chromosomal rearrangement and 214 small snakehead-specific structural variations (SSSVs) were detected between the small snakehead and other Channa species. Among these SSSVs, the deletion in pax7a was likely to play a role in the pelvic fin loss. Furthermore, the specific loss of conserved non-coding regulatory elements (CNEs) related to limb/fin development was detected in the small snakehead, which possibly led to the pelvic fin loss of the small snakehead. The present study generated the high-quality chromosome-scale reference genome of the small snakehead, which provided a valuable genomic resource for the follow-up studies, and our findings shed light on the important genetic clues regarding pelvic fin loss in the species.</p>","PeriodicalId":54811,"journal":{"name":"Journal of Heredity","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148165709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

De-extinction (i.e., the revival of genes or phenotypes of extinct species) has similarly received considerable attention in animals with little discussion in plants. De-extinction is already possible in plants, particularly for those species with close relatives for which there are rich genomic resources as well as the capacity for CRISPR-mediated gene editing and regeneration. Herbarium collections offer one important source of DNA for plants that have gone extinct in that time frame. The opportunities for de-extinction in plants will only increase as genomic resources and the tools for regeneration and genome editing improve.

However, some breeds are confined to small, isolated, and feral populations. In the United Kingdom (UK), these effectively 'wild' populations are increasingly threatened with extinction due to ongoing culling practices and inadequate legal protection, which is further compounded by the limited understanding of their genetic status and origins, both of which are critical for informed conservation management. To address this knowledge gap, we examined the genetic structure and ancestry of 20 Cheviot goats residing within Northumberland National Park using SNP genotyping. This population is hypothesised to comprise of British primitive goats, the original landrace goat breed of the British Isles. We compared our findings against over 100 global breeds and found that the Cheviot goats exhibited low SNP heterozygosity (HO = 0.23), and very high levels of inbreeding (FROH = 0.45).

Egg buoyancy is highly sensitive to salinity and represents a critical life-history trait shaping survival and recruitment. Inversions on chromosomes 2, 7, and 12 in cod are linked to salinity adaptation and might be important for egg buoyancy and survival. Here, we conducted a buoyancy test on Atlantic cod eggs, spawned from North Sea and Fjord ecotypes, using Coombs apparatus. Ecotypes and genotypes for the inversions on chromosomes 2, 7, and 12 were determined in all individuals (n = 242). We predicted that inversion genotypes and ecotypes would be associated with egg buoyancy. We found that buoyancy was variable and followed a bimodal distribution sorted by ecotype, with Fjord and North Sea individuals having mean buoyancies at neutral salinity (at 7 °C) of 27 and 31 ppt, respectively. Therefore, individuals with intermediate buoyancies might be selected against. This finding is consistent with our expectations, as Fjord ecotypes experience lower salinities compared to North Sea ecotypes. Interestingly, there was little evidence that the inversions on chromosomes 2, 7, and 12 impacted buoyancy.

To clarify the population structure and gene flow among lineages, we performed population genetic analyses based on genome-wide ddRAD-seq together with partial mitochondrial cytochrome-b sequences, using samples collected across the species' entire geographic range. Analyses of SNP data revealed three major groups (Northern, Central, and Western groups) with some hybrid populations in the contact zones. Estimation of the evolutionary history using an approximate Bayesian computation (ABC) approach suggested that the common ancestor of this species first diverged into the Northern and Western groups in middle Miocene, and that subsequent hybridization between these two groups gave rise to the Central group in the late Pliocene. An f4-test indicated gene flow from the Western group into the southwestern Central group, as well as that from the Northern group into the northeastern Central group.
