Characterization of the complete chloroplast genome of the Solanum tuberosum L. cv. Favorita (Solanaceae).

ABSTRACT: Potato (Solanum tuberosum L.), a species of the family Solanaceae, is the fourth most important food crop worldwide. Solanum tuberosum L. cv. Favorita is a long oval, smooth, yellowish-skinned potato variety with green and plump leaves. It has a dry matter content of 17.7% and starch content of 12.4-14.01% in the tuber. In order to support more genetic data for the taxonomy of S. tuberosum, the complete chloroplast (cp) genome sequence of S. tuberosum L. cv. Favorita was determined using next-generation sequencing. In leaves, the chloroplast genome accounts for 5.17% of the total genome. The entire cp genome was determined to be 155,296 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 85,737 and 18,373 bp, respectively, which were separated by a pair of 25,593 bp inverted repeat (IR) regions. The genome contained 132 total genes, including 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall GC content of the genome is 37.9%. A phylogenetic tree reconstructed by 60 chloroplast genomes reveals that S. tuberosum L. cv. Favorita is most closely related to S. tuberosum L. cv. Desiree and S. tuberosum L. cv. Atlantic.
