2026-05-25 A Dataset of 352 Nuclear Genes for Accurate Species Identification and Geographical Origin Traceability of Rhododendron dauricum L. doi:10.57760/sciencedb.30507 en This dataset comprises 355 markers for Rhododendron dauricum L. and 29 related Rhododendron species. Building upon the previously reported 352 nuclear genes, we have integrated three additional universally used DNA barcoding loci: rbcL, matK (chloroplast), and ITS (nuclear ribosomal). All markers were assembled from whole genome sequencing data of 14 R. dauricum individuals from seven populations in Northeast China, plus public data of 29 other Rhododendron species. The inclusion of rbcL, matK, and ITS not only complements the phylogenetic framework but also enhances the discrimination power for tracing the geographical provenance of R. dauricum populations.
