Data from: Chrysolaena obovata, A SPECIES NATIVE OF BRAZILIAN CERRADO: GENETIC DIVERSITY AND STRUCTURE OF NATURAL POPULATIONS AND POTENTIAL FOR INULIN PRODUCTION
<p><em>Chrysolaena obovata</em> (Less.) M. Dematteis, an herbaceous Asteraceae species widely distributed across different Brazilian Cerrado physiognomies, has underground organs, named rhizophores, that accumulate high concentrations of inulin-type fructans. These carbohydrates are recognized as beneficial soluble fibers for human health and are currently used in the food and pharmaceutical industries. Considering that fructans, in addition to their economic potential, provide plants with greater tolerance to drought, heat and cold, it is important to understand whether their metabolism is conserved in natural populations. In this work, we aimed to investigate if the levels of genetic diversity in the populations studied allow the selection of localities with a high genetic base and higher fructan content for future programs of <em>in</em> <em>situ</em> conservation and genetic improvement for inulin production. Therefore, we characterized the diversity, structure, and gene flow of seven natural populations from Brazilian Cerrado, using nine microsatellite loci (SSR). In addition, we compared whether the fructan composition varied between populations of different Cerrado phytophysiognomies. Overall, we found that <em>C. obovata</em> populations exhibited moderate levels of genetic diversity, low genetic differentiation, and high gene flow. This study identified two populations with less genetic diversity and therefore, greater attention should be given to conservation programs including these populations. Fructan metabolism is conserved in all populations, indicating that <em>C. obovata</em> is an important genetic resource with high potential for inulin production.</p> <p><strong>File descriptions</strong></p> <p>Population_code.txt - Contains a matrix that indicates the population_code, Population_name, Brazilian-state, Phytophysiognomy, Collection coordinates and Altitudes (m).</p> <p>Date_ Diaz et al.xlsx – Contains Genotypes crude of the individuals analyzed.

Data from: Diversity among rare and common congeneric plant species from the Garry oak and Okanagan shrub-steppe ecosystems in British Columbia: implications for conservation
<p>Using universal non-coding chloroplast DNA markers (cpDNA), we investigated genetic diversity and genetic structure in four rare and common plant species pairs inhabiting threatened ecosystems (Garry Oak and Okanagan shrub-steppe) in British Columbia. <span>The species found in the Garry oak ecosystem are:</span><span> </span><em>Sanicula bipinnatifida </em><span>(purple sanicle; Apiaceae; rare),</span><span> </span><em>Sanicula crassicaulis </em><span>(Pacific sanicle; Apiaceae; common), and</span><span> </span><em>Balsamorhiza deltoidea </em><span>(deltoid balsamroot; Asteraceae; rare). The species found in the Okanagan shrub-steppe ecosystem are:</span><span> </span><em>Balsamorhiza sagittata </em><span>(arrowleaf balsamroot; Asteraceae; common),</span><span> </span><em>Orthocarpus barbatus </em><span>(Grand Coulee owl-clover; Orobanchaceae; rare),</span><span> </span><em><u>Orthocarpus </u>luteus </em><span>(yellow owl-clover; Orobanchaceae; common),</span><span> </span><em>Phacelia ramosissima </em><span>(branching phacelia; Hydrophyllaceae; rare), and</span><span> </span><em>Phacelia linearis </em><span>(thread-leaved phacelia; Hydrophyllaceae; common). </span>Eight cpDNA regions were sequenced for each study species. Sequences were aligned and concatenated within each species, and single nucleotide polymorphisms (SNPs) were used to analyze patterns of regional genetic diversity and phylogeographic structure within genera and species. Results include: total gene diversity (Ht), nucleotide diversity (π), number of private alleles, haplotype networks, isolation by distance, and analysis of molecular variance. </p> <p> </p>
