Importantly, firecracker penstemon has been reported to hybridize with many other penstemons and therefore provides the opportunity to develop more tolerant elite cultivars through strategic crossing. To facilitate the study and utilization of firecracker penstemon, we sequenced and annotated the genome of a P. eatonii accession collected from Utah, United States. We also performed low-coverage whole-genome sequencing of 26 additional accessions from three different varieties of P. eatonii.

The SLICK1 allele, located in the PRLR gene, confers a short and sleek coat that is inherited as a simple dominant phenotype. Approximately 40 years ago, the University of Florida initiated efforts to introgress this allele into the Holstein population. Here we tracked the introgression of the SLICK1 allele using a medium-density genotyping array and a reference population of both breeds (50 Holstein, 46 Senepol). Among the 31 SLICK1+ Holsteins, there was 15.25% ± 11.11% (mean ± SD) Senepol ancestry on BTA20. Holsteins at the University of Florida descended from slick matings that did not inherit the SLICK1 allele (n = 9) exhibited no Senepol ancestry. A secondary introgression of Senepol genetics in SLICK1+ animals was found on BTA4, spanning 54 markers and 15 genes, with 26.67% Senepol ancestry. This region, previously linked to heat stress adaptation, suggests that the introgression extends beyond the SLICK1 allele to incorporate additional beneficial genetics for thermal stress adaptation. These findings indicate that deliberate introgression of the SLICK1 allele enhances specific traits and potentially introduces other adaptive genetic variations. The study demonstrates the successful use of genetic interventions to improve livestock resilience against environmental challenges without significantly disrupting the recipient breed's genetic structure. The introgression of the SLICK1 allele serves as a model for breeding programs aimed at optimizing animal welfare and productivity in the face of global climate change while maintaining breed integrity.","PeriodicalId":54811,"journal":{"name":"Journal of Heredity","volume":" ","pages":"216-224"},"PeriodicalIF":3.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142481272","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}

The analysis of the second exon comprising the antigen-binding region revealed high allelic diversity in all three species, but the pattern of the diversity was the most specific for the Baikal seal. This species differs from the other two by the smallest number of alleles in the population, yet they have the largest number of alleles per individual and by the maximum similarity of individual genotypes. Presumably, this specificity is a consequence of the spatial and temporal homogeneity of the Lake Baikal environment. Analysis of the third exon encoding the conserved β2-domain showed that the Baikal seal differs by the greatest number of amino acid sequences per individual, while the Caspian seal has the lowest number of variants. A single variant of the β2-domain, the same as in the ringed seal, predominates in the Caspian seal, whereas in the Baikal seal the two other variants predominate. At the same time, three species-specific amino acid sequences were observed among minor variants in the Caspian seal, while only one was found in the Baikal seal. This fact may suggest a longer period of independent evolution in the Caspian seal compared to the Baikal seal.","PeriodicalId":54811,"journal":{"name":"Journal of Heredity","volume":" ","pages":"181-192"},"PeriodicalIF":3.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142565371","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}

Comparisons were made to the Asian longhorned beetle (Anoplophora glabripennis) genome.

Manual curation identified 122 putative odorant receptors (OR) and 162 gustatory receptors (GR), the former number similar to A. glabripennis but the latter only 69% of the A. glabripennis suite. We also documented a greater percentage of pseudogenic GRs and ORs compared to A. glabripennis, suggesting an ongoing reduction in chemosensory function, perhaps related to host specialization. We found lower diversity within certain well-studied gene families predicted to encode putative plant cell wall degrading enzymes in the T. tetrophthalmus genome, perhaps also due to host specialization. Exploring genes relevant to stress and allelochemical detoxification revealed evidence of an abundance of ABC-family genes in the T. tetrophthalmus genome, which may be related to sequestering toxic cardiac glycosides.

Here we describe a methodology for identifying and genotyping thousands of SNP loci in the southern damselfly (Coenagrion mercuriale), a bioindicator of freshwater stream quality classified as near-threatened, with locally declining populations. We used a hybrid approach combining reduced representation sequencing and target enrichment. First, we identified putative SNP loci using ddRADseq and de novo assembly. Then, single primer enrichment technology targeted 6000 of these SNPs across 1920 individuals. Challenges encountered included sequence recapture failure, coverage depth discrepancies, and aberrant FIS values. We provide recommendations to address such issues. After multiple filtering steps, 2092 SNPs were retained and used to analyze the genetic structure of 131 individuals belonging to 11 populations in France, comparing central and marginal populations. Genetic differentiation was lower among central populations, with no sign of inbreeding. As compared with microsatellite loci, SNPs exhibited greater resolution in detecting fine-scaled genetic structure, and identifying putative hybrids in adjacent populations. In this study, we emphasize the difficulties of large-scale SNP genotyping in nonmodel species via a hybrid method that ultimately did not offer the expected cost and time-saving compared with classical ddRAD approaches. However, SNPs showed greater power than previously available markers in identifying conservation units or admixture events, and the panel of reusable probes we describe here offers the potential to improve conservation efforts through future diachronic studies or finer estimations of key parameters like effective population size.","PeriodicalId":54811,"journal":{"name":"Journal of Heredity","volume":" ","pages":"255-271"},"PeriodicalIF":3.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142808311","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}

Discovering the genetic basis of plasticity and plasticity variation is critical to understand how populations will respond to the ongoing environmental challenges brought about by, for example, climate change. Here, we investigate the genetic basis of the pea aphid (Acyrthosiphon pisum) wing plasticity variation. In this species, genetically identical wingless (highly fecund) and winged (dispersive) individuals are produced by pea aphid mothers in uncrowded versus crowded environments, respectively. We focus specifically on the genetic basis of the propensity to produce winged individuals in response to crowding. We crossed a low to a high plasticity line and examined plasticity variation in backcross progeny (F1 × low parent), finding that differences between lines had a strong genetic component and that multiple loci likely contribute to this variation. Transcriptional profiling revealed a candidate gene, yellow-h, which was found within a genomic locus contributing to plasticity variation. Overall, we provide novel information about the genetic basis of an ecologically relevant trait and contribute to the growing literature recognizing the importance of understanding the genetic basis of plasticity variation.","PeriodicalId":54811,"journal":{"name":"Journal of Heredity","volume":" ","pages":"272-278"},"PeriodicalIF":3.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143124106","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}
