Phylogeographic studies have revealed deeply divergent lineages across North America, as well as a single collection of an apparent social parasite in California. In light of its distinctive cold adaptation and recently discovered geographic diversity, a better understanding of the underlying genetic patterns of the winter ant is valuable to future conservation efforts for this species.

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":"","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":"","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. This study provides a foundation for cloning genes controlling flower color and advances our understanding of the molecular mechanisms regulating flower color in S. miltiorrhiza.","PeriodicalId":54811,"journal":{"name":"Journal of Heredity","volume":" ","pages":"225-240"},"PeriodicalIF":3.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143061489","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}

Although previous research has explored the ecological variables conducive to the survivability of populations of the giant salmonfly, a lack of genomic resources hampers exploration of how genetic variation is spread across extant populations.

These species are well known for their obligate social parasitism with various Formica ant species, which they kidnap in dramatic, highly coordinated raids. Kidnapped Formica larvae and pupae become integrated into the Polyergus colony where they develop into adults and perform nearly all of the necessary colony tasks for the benefit of their captors. In California, Polyergus mexicanus is the most widely distributed Polyergus, but recent evidence has identified substantial genetic polymorphism within this species, including genetically divergent lineages associated with the use of different Formica host species.

Our analysis revealed no genetic association between the ecotypes and the SNPs, suggesting that the classification is based on ecological traits rather than genetic factors. Using data from 2,641 SNPs and 164 genotypes, our Bayesian clustering analysis categorized the populations into six distinct genetic groups, distinguishing the Rapa Nui island population from those on the American mainland. The estimated effective migration rates showed low levels of migration between island and continental populations, with significant migration occurring only among populations between 29° S and 33° S. Genetic differentiation between Rapa Nui island and the American continent was observed. In contrast, no significant differentiation was noted in other regions. The haplotype network suggests a possible migration pathway from that area of the South Pacific. In addition, demographic history analysis indicates a relatively recent founder effect of Cx. pipiens s.l. on the island. Geographic isolation and variations in genetic makeup can limit the spread of pathogens regionally and globally. However, these same factors can also promote specialization and enhance adaptation to new ecological niches, thereby improving the ability of pathogens to function as effective vectors in isolated environments.","PeriodicalId":54811,"journal":{"name":"Journal of Heredity","volume":" ","pages":"241-254"},"PeriodicalIF":3.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143069194","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}

Approaches combining landscape genetic and network methodologies have shown promise in allowing for simultaneous identification of strong and vulnerable populations, and the landscape factors that may inhibit or facilitate population connectivity. Here we leverage these tools to assess the genetic structure and functional connectivity of Parnassius clodius butterflies in three protected regions in the United States, North Cascades National Park (WA), Grand Teton National Park (WY), and Yosemite National Park (CA), and determine whether these metrics vary with differences in sampling scale among regions. We also test the resilience of population connectivity to extirpation using graph-theoretic analyses (e.g. network analyses) and test the relative importance of isolation by distance (IBD), isolation by resistance (IBR), and isolation by environment (IBE) in limiting population connectivity, using butterfly habitat suitability, host plant data, terrain roughness, percent forest cover, and climate variables. Both traditional genetic clustering analyses and network analyses revealed fine-scale genetic structure across all three regions. Our network analyses revealed similarity in topology across regions despite significant landscape variation, and network sensitivity analyses revealed that P. clodius subpopulations within the Grand Teton and Yosemite NP regions are more vulnerable to perturbations. Our landscape genetic analyses suggest that environmental variation has an important impact on genetic differentiation in addition to geographical distance, but the contribution of specific variables varies across replicate landscapes.","PeriodicalId":54811,"journal":{"name":"Journal of Heredity","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144182909","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}
