The complete chloroplast genome sequence of Populus mexicana (Salicaceae)

The complete chloroplast genome sequence of Populus mexicana was characterized from Illumina pair-end sequencing. The chloroplast genome of P. mexicana was 156,188 bp in length, containing a large single-copy region (LSC) of 86,871 bp, a small single-copy region (SSC) of 16,559 bp, and 2 inverted repeat (IR) regions of 26,377 bp. The overall GC content is 36.74%, while the corresponding values of the LSC, SSC, and IR regions are 64.8, 69.3, and 60.3, respectively. The genome contains 111 complete genes, including 72 protein-coding genes (62 protein-coding gene species), 31 tRNA genes (29 tRNA species), and 8 rRNA genes (4 rRNA species). The neighbor-joining phylogenetic analysis showed that P. mexicana and Populus fremontii clustered together as sisters to other Populus species.
