The complete chloroplast genome sequence of Populus mexicana (Salicaceae)

The complete chloroplast genome sequence of Populus mexicana was characterized from Illumina pairend 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.
