Abstract:
The complete sequence of the circular mitochondrial (mt) DNA of Populus rotundifolia var. duclouxiana is presented in this study. The size of the P. rotundifolia var. duclouxiana mt genome was 775,549 bp and the GC content of the genome was 44.8%. The P. rotundifolia var. duclouxiana mt genome encoded 58 genes, including 33 protein-coding genes, 22 tRNA genes, and three rRNA genes. Among the 58 genes, three genes contained one intron, one gene contained three introns, and four genes contained four introns. Phylogenetic analysis using seven complete mt genomes of Salicaceae supported that P. rotundifolia var. duclouxiana is most closely related to P. davidiana.
