Currant tomato (Solanum pimpinellifolium), also called spoon tomato, is a wild species of tomato native to Ecuador and Peru and naturalized in the Galápagos Islands. Its small fruits are edible, and it is commonly grown in gardens as an heirloom tomato although it is considered to be wild rather than domesticated as is the commonly cultivated tomato species Solanum lycopersicum. Its genome was recently sequenced.

~ Disease Resistance ~

Its relatedness to tomatoes and ability to freely cross with them has allowed it to be used for the introduction of disease resistance traits in tomato varieties, as well as in the study of the genetic control of tomato traits such as fruit shape and size.

Only 900 Mb genome differs from the tomato at 0.6% of base pairs; in comparison, they both differ from the potato (from which they diverged 7.3 million years ago) at 8% of bases.

Considered the ancestor of domesticated tomatoes, it is valued for supplementing the limited gene pool of the domestic tomato. Due to agricultural development, the wild currant tomato is becoming less prevalent in the native range of northern Peru and southern Ecuador. In addition, seed collection is hampered by issues with the Convention on Biological Diversity.
