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

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

The complete chloroplast genome sequence of horticultural plant, Impatiens hawkeri (Sect. Balsaminacea, Impatiens)

The complete chloroplast genome sequence of Impatiens hawker, a widely cultivated horticultural species in the world is 151,692 bp, with a typical quadripartite structure including a pair of inverted repeat (IRs, 25,584 bp) regions separated by a small single copy (SSC, 17,494 bp) region and a large single copy (LSC, 83,029 bp) region. The overall GC content of I. hawker plastid genome was 36.8%. The whole chloroplast genome contains 135 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 its evolution status, the phylogenetic tree based on APGIII reveal that there are close relationships to the same genus species I. uliginosa and I. piufanensis
