The complete mitochondrial genome sequence of Populus davidiana Dode.

This study sequenced the entire mitochondrial genome of Populus davidiana Dode. It was 779,361 bp in length, containing 33 protein-coding genes, 3 rRNA genes and 22 tRNA genes and 1 pseudogene, and its GC content was 44.8%. Phylogenetic analysis was conducted using 6 mitochondrial genomes from the Salicaceae and Euphorbiaceae families, resulting that P. davidiana Dode was closely related to Populus tremula and Populus tremula × Populus alba. These results will provide fundamental data for the evolutionary studies in Populus genus.
