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

Abstract

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.
