However, how the evolutionary novelty of an adaptive immune response impacted the diversity of receptors associated with the innate immune response has received considerably less attention until recently. Here, we investigate the diversification of vertebrate toll-like receptors (TLRs), one of the most ancient and well conserved innate immune receptor families found across the Tree of Life, integrating genomic data that represent all major vertebrate lineages with new transcriptomic data from Polypteriformes, the earliest diverging ray-finned fish lineage. Our analyses reveal TLR sequences that reflect the 6 major TLR subfamilies, TLR1, TLR3, TLR4, TLR5, TLR7, and TLR11, and also currently unnamed, yet phylogenetically distinct TLR clades. We additionally recover evidence for a pulse of gene gain coincident with the rise of the RAG-mediated adaptive immune response in jawed vertebrates, followed by a period of rapid gene loss during the Cretaceous. These gene losses are primarily concentrated in marine teleost fish and synchronous with the mid Cretaceous anoxic event, a period of rapid extinction for marine species. Finally, we reveal a mismatch between phylogenetic placement and gene nomenclature for up to 50% of TLRs found in clades such as ray-finned fishes, cyclostomes, amphibians, and elasmobranchs. Collectively, these results provide an unparalleled perspective of TLR diversity and offer a ready framework for testing gene annotations in non-model species.}, journal={IMMUNOGENETICS}, author={Carlson, Kara B. and Nguyen, Cameron and Wcisel, Dustin J. and Yoder, Jeffrey A. and Dornburg, Alex}, year={2023}, month={Aug} } @article{carlson_wcisel_ackerman_romanet_christiansen_niemuth_williams_breen_stoskopf_dornburg_et al._2022, title={Transcriptome annotation reveals minimal immunogenetic diversity among Wyoming toads, Anaxyrus baxteri}, volume={4}, ISSN={["1572-9737"]}, url={https://doi.org/10.1007/s10592-022-01444-8}, DOI={10.1007/s10592-022-01444-8}, abstractNote={Briefly considered extinct in the wild, the future of the Wyoming toad (Anaxyrus baxteri) continues to rely on captive breeding to supplement the wild population. Given its small natural geographic range and history of rapid population decline at least partly due to fungal disease, investigation of the diversity of key receptor families involved in the host immune response represents an important conservation need. Population decline may have reduced immunogenetic diversity sufficiently to increase the vulnerability of the species to infectious diseases. Here we use comparative transcriptomics to examine the diversity of toll-like receptors and major histocompatibility complex (MHC) sequences across three individual Wyoming toads. We find reduced diversity at MHC genes compared to bufonid species with a similar history of bottleneck events. Our data provide a foundation for future studies that seek to evaluate the genetic diversity of Wyoming toads, identify biomarkers for infectious disease outcomes, and guide breeding strategies to increase genomic variability and wild release successes.}, journal={CONSERVATION GENETICS}, author={Carlson, Kara B. and Wcisel, Dustin J. and Ackerman, Hayley D. and Romanet, Jessica and Christiansen, Emily F. and Niemuth, Jennifer N. and Williams, Christina and Breen, Matthew and Stoskopf, Michael K. and Dornburg, Alex and et al.}, year={2022}, month={Apr} } @article{bunch_carlson_hoogakker_plough_evans_2021, title={Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus Mitchill, 1815) early life stage consumption evidenced by high-throughput DNA sequencing}, volume={37}, ISSN={["1439-0426"]}, DOI={10.1111/jai.14153}, number={1}, journal={JOURNAL OF APPLIED ICHTHYOLOGY}, author={Bunch, Aaron J. and Carlson, Kara B. and Hoogakker, Frederick J. and Plough, Louis V. and Evans, Heather K.}, year={2021}, month={Feb}, pages={12–19} } @article{evans_bunch_schmitt_hoogakker_carlson_2021, title={High-throughput sequencing outperforms traditional morphological methods in Blue Catfish diet analysis and reveals novel insights into diet ecology}, volume={11}, ISSN={["2045-7758"]}, DOI={10.1002/ece3.7460}, abstractNote={Abstract}, number={10}, journal={ECOLOGY AND EVOLUTION}, author={Evans, Heather K. and Bunch, Aaron J. and Schmitt, Joseph D. and Hoogakker, Frederick J. and Carlson, Kara B.}, year={2021}, month={May}, pages={5584–5597} }
