The complete chloroplast genome and phylogenetic analysis of Fraxinus paxiana Lingelsh. 1907 (Oleaceae)
Abstract
Fraxinus paxiana distributed in Shaanxi, Gansu, Hubei, Hunan, and Sichuan provinces, 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 Fraxinus is divided into two branches, with F. paxiana and F. insularis having the closest phylogenetic relationship.
