Abstract:
Piptanthus nepalensis (Hooker) Sweet is a semi deciduous or deciduous shrub belonging to the genus Piptanthus, Leguminosae. P. nepalensis has been used as a folk medicinal herb in Nepal and was cultivated all over the world as an ornamental plant. In the present study, we sequenced the entire genome of the chloroplast of P. nepalensis. The total length of the chloroplast genome in P. nepalensis is 152,195 bp, including a large single-copy region of 82,048 bp, a small single-copy region of 17,675 bp, and a pair of inverted repeats regions of 26,236 bp. The overall guanine-cytosine (GC) content of the genome was 36.7%. There are 131 genes in the chloroplast genome of P. nepalensis, including 85 protein-coding genes, 8 rRNA genes and 38 tRNA genes. Phylogenetic analysis showed that P. nepalensis is closely related to Maackia floribunda.
