Abstract

Impatiens mengtszeana is an endemic species in China. In this study, the complete chloroplast genome of I. mengtszeana was sequenced and analyzed. The total chloroplast genome size of I. mengtszeana is 152,928 bp, including a pair of inverted repeat regions (IRs, 26,007 bp) separated by a large single copy (LSC, 83,722 bp) region and a small single copy region (SSC, 17,192 bp). The whole chloroplast genome contains 89 protein-coding genes (PCGs), 37 transfer RNA genes (tRNAs), and eight ribosomal RNA genes (rRNAs). According to the phylogenetic topologies, I. mengtszeana was closely related to I. hawkeri.
