The plants of the fern genus Sceptridium (Ophioglossaceae) are generally considered to be predominantly selfing, making them suitable for analyzing speciation patterns and intraspecific variation characteristic of homosporous plants. The Sceptridium species in Japan not only exhibit variations in ploidy, including diploids, tetraploids, and hexaploids, but also pose taxonomic challenges due to morphologically distinctive forms that are difficult to be assigned to previously described species. We developed multiple single-copy nuclear markers and aimed to identify ancestral species of the polyploids and to elucidate the evolutionary entity of an undescribed species. Chromosome counts and analyses of individual gene trees confirmed that S. japonicum, S. atrovirens, and the undescribed species are allohexaploids originating through hybridization between a maternal tetraploid ancestor closely related to S. formosanum and a paternal diploid ancestor closely related to extant diploid species. By identifying homoeologs derived from the diploid ancestor, we successfully analyzed the phylogenetic relationship between the diploid ancestor of the hexaploid species and extant diploid species using the multispecies coalescent model. The examined undescribed species could not be distinguished from S. atrovirens by multiple nuclear markers or by SNP data obtained from multiplexed ISSR genotyping by sequencing. This species appears to represent one of the polymorphisms of S. atrovirens, which was fixed through gametophytic selfing.</p>","PeriodicalId":56109,"journal":{"name":"Molecular Phylogenetics and Evolution","volume":" ","pages":"108244"},"PeriodicalIF":3.6,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142640415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As is true for many groups, high-quality tissues were unavailable for some taxa. Thus, we explored methods for incorporating sequences derived from historical (toe pad) samples to expand the phylogenetic datasets. We recovered an average of 4,186 UCE loci and mitochondrial bycatch data (supplemented with published mitochondrial data) from 96% of all currently recognized species. We found that the UCE phylogeny built with alignments with less than 70% of gaps and ambiguities recovered the most robust phylogenetic relationships for this family, representing 101 species. Using this phylogeny as a topological backbone and adding ten fair quality \"bad\" samples effectively generated an overall well supported phylogeny, representing 108 species (∼90% of all species). Based on this tree, we then added in seven poor quality \"ugly\" samples and six of those were placed within their expected genera. We also explored the phylogenetic positions of the likely extinct Leucopeza semperi and the endangered Catharopeza bishopi where limited data was obtained. Overall, taxonomic placements in our UCE trees largely correspond to previously published studies with the recovery of all currently recognized genera as monophyletic except for Basileuterus which was rendered paraphyletic by B. lachrymosus.

This subfamily is known for its rapid evolution, adding more complexity to our efforts to unravel their evolutionary history. The main debate revolves around the recognition of the genus Peromyscus as monophyletic or paraphyletic due to its relationship with other genera such as Habromys, Megadontomys, Podomys, Neotomodon, and Osgoodomys. Here, we aim to resolve phylogenetic relationships within Neotominae, to further explore their evolutionary history and taxonomic boundaries. We used target capture and high-throughput sequencing of complete mitogenomes and thousands of genome-wide ultraconserved elements loci (UCEs). Our comprehensive analyses encompassed 53 species of Neotominae spanning 12 previously described genera, along with one yet-undescribed genus. We also investigated 12 out of the 13 species groups within Peromyscus. Our analyses including Maximum Likelihood and Bayesian Inference with both mitogemomes and UCEs, as well as the coalescent species-tree-based approach with UCEs, consistently recovered concordant and well-resolved phylogenies with high levels of nodal support. We identified seven main clades within Neotominae that could potentially be recognized at the generic level, mostly to categorize the genus Peromyscus as a monophyletic group, including one species group within \"Peromyscus\". Furthermore, our divergence dating estimates place the crown age of Neotominae to be around the late Miocene at ca. 7.9 - 10.7 mya. While generic level diversification continued through the Pliocene, species level diversification predominantly occurred during the late Pliocene, extending through the Pleistocene and Holocene. These epochs have been recognized as periods with significant changes in flora and fauna, driving ecological transformations on a global scale. We hypothesized that climatic and vegetation shifts during the Neogene and Quaternary, coupled with geological events, topographical features, and the presence of biogeographical corridors played a pivotal role in the speciation and diversification of Neotominae. Recognizing the importance of generating genomic-scale data coupled with a broad taxonomic sampling, our study, for the first time, offers resolution of the relationships among the main lineages of Neotominae. We expect that the phylogeny presented here will serve as a foundational resource for future systematic and evolutionary studies.
