The complete chloroplast genome of Impatiens uliginosa Franch., an endemic species in Southwest China.

ABSTRACT: The complete chloroplast genome sequence of Impatiens uliginosa Franch., an endemic species in Southwest China, we research genetic and phylogenetic relationship with other species in an effort to provide genomic resources useful for promoting its conservation and utilization. The total chloroplast genome size of I. uliginosa is 152,609?bp, with a typical quadripartite structure including a pair of inverted repeat (IRs, 25,871?bp) regions separated by a small single copy (SSC, 17,502?bp) region and a large single copy (LSC, 83,365?bp) region. The overall GC content of I. uliginosa plastid genome was 36.8%. The whole chloroplast genome contains 136 genes, including 89 protein-coding genes (PCGs), 38 transfer RNA genes (tRNAs), and 8 ribosomal RNA genes (rRNAs). Among these genes, 15 genes have one intron and 2 genes contain two introns. To investigate the evolution status, the phylogenetic tree based on APG III from 12 complete chloroplast plastomes of Ericales supports close relationships. According to the phylogenetic topologies, I. uliginosa was closely related to I. piufanensis.
