Complete chloroplast genome of Euphorbia micractina Boiss (Euphorbiaceae: Euphorbia)

Euphorbia micractina Boiss is a plant with high medicinal value. Yet, its molecular biology is not fully understood. In this study, we sequenced the whole chloroplast genome (CP) sequence of E. micractina to study its phylogenetic relationship in Euphorbiaceae. The total length of the chloroplast genome of E. micractina is 162,056 bp, including a large single-copy (LSC) region of 89,936bp bp, a small single-copy (SSC) region of 18,376 bp, and a pair of identical inverted repeat regions (IRs) of 11,367 bp. The genome has 128 genes, including 84 protein-coding genes, 36 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. The overall GC content of the plastome is 35.7%. The phylogenetic analysis of E. micractina with 30 related species suggested a closest taxonomical relationship with Euphorbia pekinensis in the Euphorbiaceae family.
