18 S. chilense, 17 S. peruvianum, 1 S. corneliomulleri, 1 S. ochranthum, 1 S. lycopersicoides Transcriptome
The wild tomato clade (Solanum sect. Lycopersicon) is native to the western coast of South America. The section shared a last common ancestor approximately 2-3 Mya, but has since diversified into upwards of 12 species. Intraspecific variation in plant size, shape, habit, and other characters has made systematics following the morphological species concept very difficult in the group, and widespread incomplete lineage sorting (ILS) has hampered genetic studies. To better understand the ancestry of sister species, S. chilense and S. peruvianum, we conducted individual RNA sequencing on a total of 36 individuals from different populations of these two species. One individual from two outgroup species from neighboring sections were also sequenced, S. ochranthum and S. lycopersicoides.
