In this study, we determined the complete plastome sequence of Pouteria campechiana (Kunth) Baehni (Sapotaceae) (NCBI acc. no. KX426215). This is the first time a plastome from the Sapotaceae has been sequenced. The gene order and structure of the P. campechiana plastome are collinear with those of the typical plastome of land plants. The complete plastome size is 157,922 bp in length and consists of a large single-copy region of 87,122 bp and a small single-copy region of 18,559 bp, which are separated by a pair of 26,120 bp-long inverted repeat regions. The overall A-T content of the plastome sequence is 63.2%. The plastome contains 113 genes, of which 79 are protein-coding genes, 30 are tRNA genes, and 4 are rRNA genes. Sixteen genes contain one intron and two genes have two introns. A total of 91 simple sequence repeat loci were identified within the genome. Phylogenetic analysis revealed that P. campechiana is a sister group of the Primulaceae-Ebenaceae clade with 100% bootstrap support.
