Data from: Systematics of Mukdenia and Oresitrophe (Saxifragaceae): Insights from genome skimming data
<p><span><i>Oresitrophe</i> and <i>Mukdenia</i> (Saxifragaceae) are epilithic sister genera used in traditional Chinese medicine. However, the taxonomy of <i>Mukdenia</i>, especially of<i> M. acanthifolia</i>, has been controversial. Genome skimming of <i>M. acanthifolia</i> and <i>M. rossii</i>, including three individuals for each species is reported and complete plastomes, partial mitogenomes and ETS/ITS sequences were assembled using these data. Their plastomes ranged from 156,341 bp to 157,018 bp in length and had similar structural characteristics and gene content of other flowering plants. These genomes were typically quadripartite, comprising 113 unique genes (79 protein coding genes, 30 tRNAs and 4 rRNAs). Comparative analysis showed that the plastomes of <i>Mukdenia</i> and <i>Oresitrophe</i> were relatively conservative, reflecting the genome size and structure, gene contents, RNA editing sites and codon usage. Five plastid regions that were hotspots of change (<i>trn</i>H-<i>psb</i>A, <i>psb</i>C-<i>trn</i>S, <i>trn</i>M-<i>atp</i>E, <i>pet</i>A-<i>psb</i>J and <i>ccs</i>A-<i>ndh</i>D) were identified within <i>Mukdenia</i>, and six regions (<i>trn</i>H-<i>psb</i>A, <i>pet</i>N-<i>psb</i>M, <i>trn</i>M-<i>atp</i>E, <i>rps</i>16-<i>trn</i>Q, <i>ycf</i>1 and <i>ndh</i>F) contained a higher number of species-specific parsimony-informative sites that can serve as potential DNA barcodes for species identification. To infer phylogenetic relationships between <i>Mukdenia</i> and <i>Oresitrophe</i>, we combined our data with published data based on three different datasets. The monophyly of each species (<i>O. rupifraga</i>, <i>M. acanthifolia</i> and <i>M. rossii</i>) and the inferred topology ((<i>M. rossii</i>, <i>M. acanthifolia</i>), <i>O. rupifraga</i>) were well supported in trees reconstructed using the complete plastomes, but <i>M. acanthifolia</i> and <i>M. rossii</i> did not form separate clade in the ETS+ITS data. We found low recovery of genes in the Angiosperms 353 target enrichment panel from our unenriched genome skimming data. Hybridization or incomplete lineage sorting may be the cause of discordances between the trees reconstructed from plastid and nuclear data. The results from this study suggest that <i>M. acanthifolia</i> should be treated as a distinct species.</span></p>
Stable persistence of relict populations involved evolutionary shifts of reproductive characters in the genus Tanakaea (Saxifragaceae)
<p class="MsoNormal"><span>Tertiary relicts often show evolutionary stasis in morphology and ecology and have been hypothesised to retain stable population sizes in refugia. However, recent studies have reported that some relicts evolutionarily shifted their physiology, ecology, and morphology and experienced various patterns of demography. To understand the historical survival of relict plants, a multidimensional study investigating the evolution of ecological and morphological traits as well as population demographic history is needed. The g</span><span>enus </span><span><span><em>Tanakaea </em></span></span><span>(Saxifragaceae) comprises two species in China and Japan. These species share most vegetative characteristics and are sometimes treated as a single species. The distribution pattern is relictual, as the populations are confined to small areas in mesic warm temperate forests less influenced by Quaternary glacial climates.</span><span> Focusing on the relictual plant group, this study tested the hypotheses of evolutionary stasis and population stability in long-term refugia. </span><span>Genetic analyses using</span><span><span> </span></span><span>plastome sequences and genome-wide single nucleotide polymorphisms revealed divergence of the two species approximately 6.8 million years ago and strong genetic differentiation of the regional populations. Demographic analysis revealed that almost all populations retained stable population sizes during glacial-interglacial climate changes, supporting the traditional view. However, morphological assessments revealed a simultaneous shift in breeding systems (from </span><span>hermaphrodite</span> <span>to dioecy/non-clonal to clonal reproduction) in Japanese species and intraspecific differentiation of leaf traits. Therefore, the relict species do not show evolutionary stasis in every aspect. Changes in reproductive characteristics may have contributed to their long-term</span><span><span> <em>in situ</em> </span></span><span>survival.</span></p>
