The complete chloroplast genome and phylogenetic analysis of <i>Fraxinus paxiana</i> Lingelsh. 1907 (Oleaceae)

<i>Fraxinus paxiana</i> distributed in Shaanxi, Gansu, Hubei, Hunan, and Sichuan provinces<i>,</i> is used as a local medicine in Shaanxi and also serves as an adulterant of traditional Chinese medicine Qinpi. Here, we assembled its 155,692 bp chloroplast genome (GC content 37.87%) with a typical quadripartite structure. A total of 133 genes were annotated, including 88 protein-coding genes, 37 tRNA genes, and eight rRNA genes. We identified 43 SSRs, predominantly composed of mononucleotide repeats. Phylogenetic analysis showed that the genus <i>Fraxinus</i> is divided into two branches, with <i>F. paxiana</i> and <i>F. insularis</i> having the closest phylogenetic relationship.
