The complete chloroplast genome sequence of Laplacea alpestris and its phylogenetic position

Abstract

Laplacea alpestris is a member of the genus Laplacea, which distributes in Central and South America. Genetic information of L. alpestris would provide guidance for the phylogenetic position of this species. Here, we reported and characterized its complete chloroplast (cp) genome using Illumina pair-end sequencing data. The total chloroplast genome size of this species was 157,211 bp, including inverted repeats (IRs) of 26,103 bp, separated by a large single copy (LSC) and a small single copy (SSC) of 86,749 and 18,256 bp, respectively. A total of 132 genes, including 37 tRNA, 8 rRNA, and 87 protein-coding genes were identified. Phylogenetic analysis showed that L. alpestris formed a monophyletic clade with Laplacea fruticosa, and then grouped with Apterosperma oblata. The systematic position of Southeast Asian Laplacea species needs further studies.
