Summary

DNA barcoding is a method of identifying species by analyzing one or a few short standardized DNA sequences.There are particular challenges in barcoding plants,especially for distinguishing closely related species.Hence,there is an urgent need to evaluate the performance of candidate loci for distinguishing between species,especially closely related species,to complement the rbcL + matK combination suggested as the core barcode for land plants.We sampled 48 individuals representing 12 species in Primula sec...
