Solanum galapagense-derived purple tomato fruit color is conferred by novel alleles of the anthocyanin fruit and atroviolacium loci.

ABSTRACT: One hypothesis for the origin of endemic species of tomato on the Galápagos islands postulates a hybridization of Solanum pimpinellifolium and Solanum habrochaites. Solanum galapagense accession LA1141 has purple fruit pigmentation, previously described in green-fruited wild tomatoes such as S. habrochaites or Solanum chilense. Characterization of LA1141 derived purple pigmentation provides a test of the hybridization hypothesis. Purple pigmentation was recovered in progenies derived from LA1141, and the anthocyanins malvidin 3(coumaroyl)rutinoside-5-glucoside, petunidin 3-(coumaroyl) rutinoside-5-glucoside, and petunidin 3-(caffeoyl)rutinoside-5-glucoside were abundant. Fruit color was evaluated in an introgression population, and three quantitati
