The complete chloroplast genome sequence of the biofuel plant Sacha Inchi, Plukenetia volubilis.

Sacha Inchi (Plukenetia volubilis) is a potential woody oil seed plant for producing healthy vegetable oil due to high content of α-linolenic acid in its seeds. In this study, we report the structure of the complete chloroplast genome of P. volubilis using high-throughput next-generation sequencing technology. The circular chloroplast genome is 161,733 bp in size, containing a pair of inverted repeat regions (IR) of 27,382 bp each, which were separated by a large single copy region (LSC) of 88,843 bp and a small single copy region (SSC) of 18,126 bp. The chloroplast genome harbors 135 genes, including 92 protein-coding genes, 35 tRNA genes and 8 rRNA genes. Based on the phylogenetic relationships between the chloroplast genome of P. volubilis and those of the other species, P. volubilis is most closely related to castor bean (Ricinus communis).
