What are the genes involved and where did they come from?
Aubergine (Abg), Anthocyanin fruit tomato (Aft) and atroviolaceae (atv) are genes introgressed from the wild species Solanum lycopersicoides, S. chilense, S. cheesemanii, respectively. The original introgression from wild species into cultivated tomato was done by other researchers. We discovered that when you combine these genes, you get an intensification of the pigment. The ‘Purple Smudge’ variety has a gene similar to Aft but it comes from a different wild species (S. peruvianum).
