Dissection for floral micromorphology and plastid genome of valuable medicinal borages Arnebia and Lithospermum (Boraginaceae)
<p>The genera <em>Arnebia </em>and <em>Lithospermum </em>(Lithospermeae-Boraginaceae) comprise 25–30 and 50–60 species, respectively. Some of them are economically valuable, as their roots frequently contain a purple-red dye used in the cosmetic industry. Furthermore, dried roots of <em>Arnebia euchroma</em>, <em>A. guttata</em>, and <em>Lithospermum erythrorhizon</em>, which have been designated Lithospermi Radix, are used as traditional Korean herbal medicine. This study is the first report on the floral micromorphology and complete chloroplast (cp) genome sequences of <em>A. guttata </em>(including <em>A. tibetana</em>), <em>A. euchroma</em>, and <em>L. erythrorhizon</em>. We reveal great diversity in floral epidermal cell patterns, gynoecium, and structure of trichomes. The cp genomes were 149,361–150,465 bp in length, with conserved quadripartite structures. In total, 112 genes were identified, including 78 protein-coding regions, 30 tRNA genes, and four rRNA genes. Gene order, content, and orientation were highly conserved and were consistent with the general structure of angiosperm cp genomes. Comparison of the four cp genomes revealed locally divergent regions, mainly within intergenic spacer regions (<em>atpH-atpI, petN-psbM, rbcL-psaI, ycf4-cemA, ndhF-rpl32, </em>and <em>ndhC-trnV-UAC</em>). To facilitate species identification, we developed molecular markers <em>psaA- ycf3 </em>(PSY), <em>trnI-CAU- ycf2 </em>(TCY), and <em>ndhC-trnV-UAC</em> (NCTV) based on divergence hotspots. High-resolution phylogenetic analysis revealed clear clustering and a close relationship of <em>Arnebia </em>to its <em>Lithospermum </em>sister group, which was supported by strong bootstrap values and posterior probabilities. Overall, gynoecium characteristics and genetic distance of cp genomes suggest that <em>A. tibetana</em>, might be recognized as an independent species rather than a synonym of <em>A. guttata</em>. The present morphological and cp genomic results provide useful information for future studies, such as taxonomic, phylogenetic, and evolutionary analysis of Boraginaceae.</p>
Data from: Comparing and co-analysing microsatellite and morphological data for species delimitation in the New Zealand native Myosotis pygmaea species group (Boraginaceae)
Delimiting species boundaries in recent plant radiations can be challenging. The New Zealand native Myosotis pygmaea (Boraginaceae) species group is a case in point. This species complex is of interest as it includes threatened species as well as possibly threatened unnamed putative taxa. Integrative taxonomic approaches using multiple lines of evidence are frequently used to overcome the difficulties of identifying lineages resulting from recent radiations. Here we analyse genotypic data from nearly 500 Myosotis individuals using microsatellite markers, and compare and co-analyse this dataset with previously published morphological data. Within the M. pygmaea group, several genetic clusters can be identified, none of which align exactly with the current taxonomy and morphological variation previously identified. When co-analysing the molecular and morphological data, M. brevis can be distinguished from the remainder of the M. pygmaea species group, but no other species or previously recognised morphological groups are supported. Other groupings within the molecular dataset appear to reflect geographic structure. Within the M. pygmaea species group, the resulting pattern of low within, and high between, population genetic variation is consistent with self-fertilization and low levels of seed dispersal.
Data from: Onosma lhokaensis (Boraginaceae), a new species from Xizang, China
A new species of Boraginaceae, Onosma lhokaensis, is described and illustrated from Xizang, China. The new species closely resembles O. waddellii and O. waltonii in having azure corollas, coherent anthers and glabrous filaments, but differs in having particularly bristly indumentum, observably narrow corolla, longer calyxes and anthers, and remarkable nutlets with stipitate cicatrix. An updated key to the species of Onosma from Xizang is also provided.
