Description of two new species and phylogenetic placement of recent taxonomic novelties in the Chilean endemic genus Miersia (Gilliesieae, Allioideae, Amaryllidaceae)
<p>Abstract: Two new species in the Chilean endemic genus <em>Miersia</em> (Gilliesieae, Allioideae, Amaryllidaceae) are introduced: <em>M. stellata</em> and <em>M. raucoana</em>. A morphological description, distribution map, illustration, and the assessment of their conservation status are provided for each new taxon, along with an updated key to all species in <em>Miersia</em>. Additionally, analyses of DNA sequences were performed to inquire the evolutionary affinities of both new species and the recently described, <em>M. putaendensis</em>, within Gilliesieae phylogenetic framework. Data from multiple single-copy nuclear genes, as well as the inclusion of <em>Trichlora</em> and <em>Schickendantziella</em>, are necessary to corroborate the tribe’s phylogeny and reassess its generic classification.</p> <p>Dataset description: Two phylip alignment files were uploaded: 1) Miersia_nov_ITS_3.0.phy, includes sequences of nrDNA ITS (nrITS) region, and 2) Miersia_nov_cpDNA_3.0.phy, includes concatenated sequences of two chloroplast (cpDNA) markers, <em>trnL-F</em> and <em>rbcL</em>. Sequences were aligned using MAFFT v.1.4.0.</p> <p>Three *.bestTree.tre files for 1) nrITS, 2) cpDNA, and 3) concatenated dataset of all loci (nrITS, <em>trnL-F</em>, <em>rbcL</em>). All were inferred using RAxML-NG v.1.1.0 (Kozlov et al. 2019), GTR+Γ as the model of molecular evolution (--model GTR+G), and partitioned by locus. nrITS and cpDNA analyses were performed conducting 50 tree searches using 25 random and 25 parsimony-based starting trees to pick the best-scoring topology (--tree pars{25},rand{25}), and the concatenated analysis included 100 tree searches using 50 random and 50 parsimony-based starting trees (--tree pars{50},rand{50}). </p> <p>Also, the respective boostrap trees (*.bootstraps.tre) were uploaded for each analysis. Likelihood bootstrap analyses were conducted in RAxML-NG v.1.1.0 with 1,000 pseudoreplicates (--bs-trees 1000).</p> <p>We also uploaded two Nexus files which correspond to sequence data from Escobar et al. (2020, Bot. J. Linn. Soc. 194: 84–99), considering that these are currently not available in TreeBase.</p>

Data from: Deep reticulation and incomplete lineage sorting obscure the diploid phylogeny of rain-lilies and allies (Amaryllidaceae tribe Hippeastreae)
Hybridization is a frequent and important force in plant evolution. Next-generation sequencing (NGS) methods offer new possibilities for clade resolution and ambitious sampling of gene genealogies, yet difficulty remains in detecting deep reticulation events using currently available methods. We reconstructed the phylogeny of diploid representatives of Amaryllidaceae tribe Hippeastreae to test the hypothesis of ancient hybridizations preceding the radiation of its major subclade, Hippeastrinae. Through hybrid enrichment of DNA libraries and NGS, we obtained data for 18 nuclear loci through a curated assembly approach and nearly complete plastid genomes for 35 ingroup taxa plus 5 outgroups. Additionally, we obtained alignments for 39 loci through an automated assembly algorithm. These data were analyzed with diverse phylogenetic methods, including concatenation, coalescence-based species tree estimation, Bayesian concordance analysis, and network reconstructions, to provide insights into the evolutionary relationships of Hippeastreae. Causes for gene tree heterogeneity and cytonuclear discordance were examined through a Bayesian posterior predictive approach (JML) and coalescent simulations. Two major clades were found, Hippeastrinae and Traubiinae, as previously reported. Our results suggest the presence of two major nuclear lineages in Hippeastrinae characterized by different chromosome numbers: 1) Tocantinia and Hippeastrum with 2n = 22, and 2) Eithea, Habranthus, Rhodophiala, and Zephyranthes mostly with 2n = 12, 14, and 18. Strong cytonuclear discordance was confirmed in Hippeastrinae, and a network scenario with at least six hybridization events is proposed to reconcile nuclear and plastid signals, along a backbone that may also have been affected by incomplete lineage sorting at the base of each major subclade.
