Studies of Tetraopes and their host plants have revealed compelling evidence for insect-plant coevolution and cospeciation. We sequenced, assembled, and annotated the genome of the common red milkweed beetle, Tetraopes tetrophthalmus, and explored gene content and evolution, focusing on annotated genes putatively involved in chemosensation, allelochemical detoxification, and phytophagy. Comparisons were made to the Asian longhorned beetle (Anoplophora glabripennis) genome. The genome assembly comprised 779 Mb distributed across 1,057 contigs, with an N50 of 2.21 Mb and 13,089 putative genes, including 97.3% of expected single-copy orthologs. 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. Our studies further illuminate the genomic basis and evolution of chemosensation in longhorn beetles and provide a new vantage point from which to explore the ecology and evolution of specialized plant-feeding in Tetraopes and other phytophagous beetles.","PeriodicalId":54811,"journal":{"name":"Journal of Heredity","volume":" ","pages":"303-314"},"PeriodicalIF":3.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142114896","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}

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}

Here we investigate the molecular basis of plumage polymorphism in both adult and juvenile black sparrowhawks (Accipiter melanoleucus), an African raptor that occurs in two adult color morphs, light and dark, and also exhibits variation in juvenile plumage coloration. Our results confirmed that plumage differences in adult morphs were a result of differential deposition of eumelanin in their ventral contour feathers. No polymorphisms in the coding regions of the MC1R or the agouti signaling protein (ASIP) genes associated with adult color morph were identified. However, lack of pigmentation in the developing breast feathers of light morph birds was strongly associated with elevated ASIP expression, and concomitant downregulation of the downstream melanogenesis genes microphthalmia-associated transcription factor (MITF), tyrosinase (TYR), and tyrosinase-related protein 1 (TYRP1). Variation in the rufous colored plumage of juveniles was found to be due to covariation in eumelanin and pheomelanin levels in dorsal and ventral contour feathers. As in adult birds, an inverse relationship between melanin pigmentation and ASIP expression was observed. This covariation between eumelanin and pheomelanin levels is not consistent with the pigment type-switching model of melanogenesis, where increased ASIP expression results in a switch from eumelanin to pheomelanin production. This highlights the need for caution when extrapolating results from model systems to other animals and the value of conducting research in wild species.","PeriodicalId":54811,"journal":{"name":"Journal of Heredity","volume":" ","pages":"193-207"},"PeriodicalIF":3.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12130442/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142649486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To elucidate the regulatory mechanisms underlying flower color, we conducted QTL mapping and identified candidate genes involved in anthocyanidin accumulation. Total anthocyanidin content and six anthocyanidins in the corollas of S. miltiorrhiza were quantified using the pH differential method and HPLC, respectively. Composite interval mapping was employed to identify QTLs, followed by the identification of candidate genes based on stable QTL intervals across at least two different planting environments. These candidate genes were further validated through gene cloning and expression analysis. Anthocyanidin analysis in the F2 population revealed a positive correlation between total anthocyanidin content and flower color intensity. Notably, three major anthocyanidins of delphinidin (Dp), cyanidin (Cy), and petunidin (Pt) were detected in varying degrees of purple flowers, whereas no anthocyanidins were found in white flowers. In total, 33 QTLs associated with anthocyanidin content were identified, with two major QTLs located in linkage groups LG4 and LG5. Two candidate genes, CHS1 (a chalcone synthase) and TCP15 (a transcription factor), were identified in the genetic intervals of two major QTL sites, respectively. Preliminary verification experiments suggest that CHS1 may play a positive role in anthocyanidin biosynthesis, whereas TCP15 appears to potentially act as a negative regulator.
