The complete chloroplast genome sequence of Populus wilsonii based on landscape design, and a comparative analysis with other Populus species

In the landscape planning and design, the ecological concept should occupy a dominant position, and the construction of an ‘environmentally friendly, resource-saving’ ecological new city is inseparable from the cultivation of forest tree species. Populus wilsonii, is an important landscape design tree species. Populus wilsonii, is also an important ecological role in boreal and temperate forests, serving as wildlife habitats and watersheds and is an important landscape ornamental tree species. The complete chloroplast genome sequence of Populus wilsonii was characterized from Illumina pair-end sequencing. The chloroplast genome of P. wilsonii was 155,716 bp in length, containing a large single-copy region (LSC) of 85,022 bp, a small single-copy region (SSC) of 16,626 bp, and two inverted repeat (IR) regions of 27,034 bp. The overall GC content is 36.70%, while the correponding values of the LSC, SSC, and IR regions are 34.5%, 30.6%, and 42.0%, respectively. The genome contains 129 complete genes, including 84 protein-coding genes (62 protein-coding gene species), 37 tRNA genes (29 tRNA species) and 8 rRNA genes (4 rRNA species). The Neighbour-joining phylogenetic analysis showed that P. wilsonii and Populus cathayana clustered together as sisters to other Populus species.
