Comparative chloroplast genome analysis of five widespread species (Zanthoxylum L.) and development of molecular markers for their discrimination
BackgroundZanthoxylum L., an important genus in the Rutaceae family, has great edible and medical values.However, the high degree of morphological similarity among Zanthoxylum species and the lack of sufficient chloroplast (cp) genomic resources have greatly impeded germplasm identification and phylogenetic analyses of Zanthoxylum.MethodsHere we as
