Spooner et al. (2005) looked at nuclear and chloroplast markers of potato varieties in India that presumably resembled the original subsp. andigenum introductions, because late blight did not arrive in India until 1870. They found that the early introductions to India already contained material of both subspecies. , 2007). Ames and Spooner (2008) studied historical herbarium specimens and concluded that although the Andean potato appeared in Europe first, the Chilean potato was already present long before the late blight epidemics.
Lycopersicum, and compared these with the genome organization of two other representatives of the Solanaceae with completely sequenced chloroplast genomes, Nicotiana and Atropa. They compared these taxa for gene content and gene order, and distribution and location of repeated sequences. Not surprisingly, they found that sequence divergence corresponded to the phylogenetic relationships, with the two most closely related species, potato and tomato, having the lowest divergence values for all classes of genes.
The diploid S. stenotomum is considered to be the most primitive cultigen, and in its turn, the progenitor of all other cultivated material, including the tetraploid S. tuberosum subsp. andigenum, the group of South American landraces from which the modern cultivated potato, S. tuberosum subsp. tuberosum, was derived. Crosses between S. stenotomum and S. megistacrolobum, Solanum acaule and S. tuberosum subsp. andigenum led to the diploid S. juzepczukii and S. chaucha, respectively. Crosses between S.
