Comparison of the complete plastomes and the phylogenetic analysis of Paulownia species.

ABSTRACT: Paulownia species are important ecological, economic and ornamental species, but their phylogenetic relationship remains unclear, which seriously affects the development and utilization of these important resources. The complete chloroplast genomes of six Paulownia species were assembled by next-generation sequencing data. By adding two known Paulownia chloroplast genomes to these six assembled genomes, we performed the comparative analysis and phylogenetic tree reconstruction of Paulownia. The results indicated that the chloroplast genomes of Paulownia species ranged in size from 154,107 to 154,694 bp. These chloroplast genomes contained 117 unique functional genes, including 80 protein-coding genes, four rRNA genes, and 33 tRNA genes. Twelve hotspot regions, five protein-coding genes and
