Evolution of the Araliaceae family inferred from complete chloroplast genomes and 45S nrDNAs of 10 Panax-related species

Abstract We produced complete sequences and conducted comparative analysis of the maternally inherited chloroplast (cp) genomes and bi-parentally inherited 45S nuclear ribosomal RNA genes (nrDNA) from ten Araliaceae species to elucidate the genetic diversity and evolution in that family. The cp geno...
