The first complete plastome sequence from the family Sapotaceae, <i>Pouteria campechiana</i> (Kunth) Baehni

Abstract

In this study, we determined the complete plastome sequence of <i>Pouteria campechiana</i> (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 <i>P. campechiana</i> 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 <i>P. campechiana</i> is a sister group of the Primulaceae-Ebenaceae clade with 100% bootstrap support.
