# Characterization of the complete chloroplast genome of Xantolis weimingii Huan C. Wang et Feng Yang et al. 2024 (Sapotaceae, Chrysophylloideae) and its phylogenetic implications

## TL;DR

This paper presents the first complete chloroplast genome of Xantolis weimingii and its evolutionary relationships within the Chrysophylloideae subfamily.

## Contribution

The study provides the first assembled chloroplast genome for the genus Xantolis and its phylogenetic placement in the Sapotaceae family.

## Key findings

- The chloroplast genome of X. weimingii is 158,458 bp in size with typical structural regions.
- It contains 114 annotated genes, including 75 protein-coding genes.
- Phylogenetic analysis shows X. weimingii is sister to other Chrysophylloideae members with strong support.

## Abstract

Xantolis weimingii is a species recently described in 2024. In this study, we reported the complete chloroplast (cp) genome of X. weimingii, representing the first assembly of the genome of a Xantolis species. The chloroplast genome of X. weimingii was 158,458 bp in size, comprising a large single-copy (LSC) region of 87,778 bp, a small single-copy (SSC) region of 18,516 bp, and two inverted repeat (IR) regions of 26,082 bp each. A total of 114 distinct genes were annotated, including 75 of which are protein-coding genes, 30 tRNA genes, 4 rRNA genes, and five open reading frames. The Maximum Likelihood (ML) phylogenetic analysis showed that X. weimingii was sister to other members of the subfamily Chrysophylloideae with strong support.
