The third complete chloroplast genome of Melicope pteleifolia (Rutaceae): a widely used folk medicinal herb

Abstract

Melicope pteleifolia commonly known as thin evodia, is an herb used to therapy eczema, dermatitis, and other ailments in traditional Chinese medicine. Here, we reported the third complete chloroplast genome of M. pteleifolia based on next-generation sequencing. The third chloroplast genome of M. pteleifolia is 158,933 bp in length consisting of large and small single-copy regions of length 85,020 and 18,607 bp, separated by two IR regions of 27,683 bp. The overall GC content was 38.30%. De novo assembly and annotation showed the chloroplast genome of M. pteleifolia encodes 134 genes, including 89 protein-coding genes, 37 tRNA genes, and eight rRNA genes. A huge intraspecies variation was found with 248 SNPs and 97 INDELs among three assemblies of M. pteleifolia. Phylogenetic tree indicated that three assemblies of M. pteleifolia form a clade, sister to the genus Phellodendron and Casimiroa.
