Abstract 

The complete nucleotide sequence of the chloroplast genome of potato Solanum tuberosum L. cv. Desiree was determined. The circular double-stranded DNA, which consists of 155,312 bp, contains a pair of inverted repeat regions (IRa, IRb) of 25,595 bp each. The inverted repeat regions are separated by small and large single copy regions of 18,373 and 85,749 bp, respectively. The genome contains 79 proteins, 30 tRNAs, 4 rRNAs, and unidentified genes. A comparison of chloroplast genomes of seven Solanaceae species revealed that the gene content and their relative positions of S. tuberosum are similar to the other six Solanaceae species. However, undefined open reading frames (ORFs) in LSC region were highly diverged in Solanaceae species except N. sylvestris. Detailed comparison was identified by numerous indels in the intergenic regions that were mostly located in the LSC region. Among them, a single large 241-bp deletion, was not associated with direct repeats and found in only S. tuberosum, clearly discriminates a cultivated potato from wild potato species Solanum bulbocastanum. The extent of sequence divergence may provide the basis for evaluating genetic diversity within the Solanaceae species, and will be useful to examine the evolutionary processes in potato landraces.
