文摘

Populus rotundifolia, which is an endemic of the Himilayas and adjacent regions, is the species that occupy the highest habitat in the Populus genus. In this study, we assembled its complete chloroplast genome. The total genome size of P. rotundifolia is 155,373 bp in length, containing a large single-copy region of 84,603 bp, a small single-copy region of 16,806 bp and a pair of inverted repeat regions of 26,982 bp. We annotated 131 genes in the genome, including 86 protein-coding genes (78 PCG species), 8 rRNA genes (4 rRNA species), and 37 tRNA genes (30 tRNA species). Among these, 19 genes were duplicated in the inverted repeats. Phylogenetic analysis suggested that, among all reported poplar chloroplast genomes, P. rotundifolia is most closely related to the common aspen (P. tremula).
