Sequencing and characterization the complete chloroplast genome of the potato, Solanum tuberosum L.

Abstract

Potato (Solanum tuberosum L.) is one of the top five staple foods in China. It has high nutritional value, adaptability, and large yield. It is the third most important food crop in the world, second only to wheat and rice. In this study, we obtained the complete chloroplast genome sequence of Potato using BGISEQ-500 sequencing. Its chloroplast genome size has 155,732 bp, containing a large single copy region (85,736 bp), a small single copy region (18,384 bp), and a pair of IR regions (25,596 bp). The overall GC contents of the chloroplast genome were 37.8%. This circular genome contains 130 annotated genes, including 85 protein-coding genes, 37 tRNAs, and eight rRNAs. Maximum likelihood phylogenetic analysis the phylogenetic relationship analysis using Neighbour-Joining (NJ) method showed that Potato (S. tuberosum L.) is much closely related to Solanum bulbocastanum. This complete chloroplast genomes can be subsequently used for the genetic breeding and useful to study the evolutionary processes in Solanaceae.
