The complete mitochondrial genome of heartbreak grass Gelsemium elegans (Gardner & Champ.) Benth. (Gelsemiaceae)

Abstract

Gelsemium elegans, endemic to southern Asia, is a highly toxic plant with various medicinal functions. The complete mitochondrial genome of G. elegans was sequenced and assembled in this study. The genome is 405,990 bp in length and contains 37 protein-coding genes, 20 tRNA genes, and 3 rRNA genes. The phylogenetic tree based on 15 protein-coding genes common to six mitochondrial genomes in Gentianales support that G. elegans of Gelsemiaceae is sister to Apocynaceae.
