''Solanum pimpinellifolium'', commonly known as the currant tomato, is a wild species of tomato〔http://solgenomics.net/about/solanum_nomenclature.pl, Sol Genomics, New nomenclature for lycopersicon, Retrieved February 17, 2013, from Spooner, D.M., I.E. Peralta & S. Knapp. AFLP phylogeny of wild tomatoes (L. section Lycopersicon (Mill.) Wettst. subsection Lycopersicon ). Taxon, in press.〕 native to Ecuador and Peru but naturalized elsewhere, such as the Galápagos Islands. Its small fruits are edible, and it is commonly grown in gardens as an heirloom tomato,〔http://www.tomatocasual.com/2008/04/18/smallest-tomato-the-currant-tomato-and-other-small-wonders, Tomato Casual: Smallest Tomato: The Currant Tomato and other Small Wonders, Retrieved February 18, 2013.〕 although it is considered to be wild rather than domesticated as is the commonly cultivated tomato species ''Solanum lycopersicum''. Its genome was recently sequenced. ==Breeding purposes== It will hybridize with common domestic tomatoes.〔http://solgenomics.net/chado/organism.pl?organism_id=770, Sol Genomics, Species: Solanum pimpinellifolium, Retrieved January 28, 2011.〕 There are annual, biennial, and perennial varieties.〔http://www.nhm.ac.uk/research-curation/research/projects/solanaceaesource/taxonomy/description-detail.jsp?spnumber=4614, Natural History Museum, Solanaceae Source, Solanum pimpinellifolium L., Cent. Pl. 1: 8. 1755. Type: Cultivated in Uppsala, Anon. (lectotype, LINN 248.15 (neg. 6802 ), designated by Knapp & Jarvis 1990), Retrieved January 28, 2011.〕 ''Solanum pimpinellifolium'' is important in tomato breeding. 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.〔 Its 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.〔〔http://www.npr.org/templates/story/story.php?storyId=126907678〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Solanum pimpinellifolium」の詳細全文を読む スポンサード リンク
