Multiplexed amplicon sequencing offers a cost-effective and rapid solution for phylogenomic studies that include large number of individuals. Selecting informative genetic markers is critical initial step in designing such multiplexed panels, but screening various genomic data selecting are the question at hand can be laborious. Here, we present flexible user-friendly tool, HiMAP2, identifying, visualizing filtering phylogenetically loci from diverse transcriptomic resources. This bioinformatics pipeline includes orthology prediction, exon extraction aligned sequences according to user-defined specifications. Additionally, HiMAP2 facilitates exploration final filtered exons by incorporating phylogenetic inference individual trees with raxml-ng as well estimation species tree using astral. Finally, results marker selection visualized refined an interactive Bokeh application used generate publication-quality figures.

Abstract The operculated land snail family Pupinidae from mainland Southeast Asia has been systematically revised based on shell morphology. Despite previous morphological studies, the evolutionary relationships within this remained unclear. This study represents first comprehensive molecular phylogeny of group, utilising two mitochondrial (COI and 16S rRNA) nuclear (5.8S rRNA + ITS2 28S genetic markers. Additionally, we conducted phylogenetic analyses Pupina species 1106 loci generated through double‐digest restriction site‐associated DNA sequencing (ddRADseq). It turned out that Asian Pollicaria emerged as a sister clade to Central American Aperostoma Megalomastomatidae, leading resurrection Pollicariidae. Among remaining pupinid genera, Tortulosa was nested Coptocheilus clade, while Pupinella were not monophyletic. previously recognised arula group found be monophyletic reclassified into Tylotoechus (formerly subgenus), distinctive conchological characters such an extending parietal tooth callus wide, outward‐curving posterior canal. However, some retrieved monophyletic, suggesting presence multiple ‘cryptic species’. Divergence time estimation indicated split could date back Late Triassic Early Cretaceous, with diversification genera occurring during Middle Jurassic Cretaceous. successful reconstruction robust using ddRADseq demonstrates significant potential RADseq techniques in elucidating deeply divergent taxa. Further studies incorporating type destructus keraudrenii are necessary justify usage these genera.

Abstract Background The Hengduan Mountains (HDM) are one of the major global biodiversity hotspots in world. Several evolutionary scenarios, especially in-situ diversification, have been proposed to account for high species richness temperate plants. However, peripatric speciation, an important mode allopatric has seldom reported this region. Results Here, two chloroplast DNA regions and 14 nuclear loci were sequenced 112 individuals from 10 populations Torreya fargesii var. 63 6 T. yunnanensis . Population genetic analyses revealed that varieties well differentiated genetically ( F ST , 0.5765) uneven diversity π 0.00221 vs. 0.00073 on average loci). gene genealogical relationship showed is inferred as derived which was further supported by coalescent simulations (DIYABC, fastsimcoal2 IMa2). By simulations, divergence time (~ 2.50–3.65 Ma) weak flow between detected. asymmetrical only occurred later stages divergence, caused second contact due population expansion 0.61 In addition, niche modeling indicated geographically ecologically unbalanced distribution range. Conclusions Overall, always parapatric with respect latter former peripatry HDM following a colonization central China during late Pliocene.
