The complete chloroplast genome sequence of Dieffenbachia seguine (Araceae)

Abstract

The nucleotide sequence of the chloroplast genome from Dieffenbachia seguine is the first to have complete genome sequence from genus of Dieffenbachia family Araceae. The genome size is 163 699 bp in length, with 36.4% GC content. A pair of inverted repeats (IRs, 25 235 bp) is separated by a large single copy region (LSC, 90 780 bp) and a small single copy region (SSC, 22 449 bp). The chloroplast genome contains 113 unique genes, 88 protein-coding genes, 37 tRNA genes, and four rRNA genes. In these genes, 16 genes contained single intron and two genes composed of double introns. A maximum likelihood phylogenetic analysis using complete chloroplast genome revealed that Dieffenbachia seguine belongs to the Araceae family of the Arecidae group, which is conform to the traditional classification.
