The tomato genome sequence providies insights into fleshy fruit evolution Tomato Genome Consortium Orozco López, Modesto Genomes Tomàquets Genomes Tomatoes Tomato (Solanum lycopersicum) is a major crop plant and a model system for fruit development. Solanum is one of the largest angiosperm genera1 and includes annual and perennial plants from diverse habitats. Here we present a high-quality genome sequence of domesticated tomato, a draft sequence of its closest wild relative, Solanum pimpinellifolium2, and compare them to each other and to the potato genome (Solanum tuberosum). The two tomato genomes show only 0.6% nucleotide divergence and signs of recent admixture, but show more than 8% divergence from potato, with nine large and several smaller inversions. In contrast to Arabidopsis, but similar to soybean, tomato and potato small RNAs map predominantly to gene-rich chromosomal regions, including gene promoters. The Solanum lineage has experienced two consecutive genome triplications: one that is ancient and shared with rosids, and a more recent one. These triplications set the stage for the neofunctionalization of genes controlling fruit characteristics, such as colour and fleshiness. 2012-07-05T10:49:02Z 2012-07-05T11:58:42Z 2012-05-30 2012-07-05T10:48:08Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0028-0836 https://hdl.handle.net/2445/28463 614256 22660326 eng Versió postprint del document publicat a: http://dx.doi.org/10.1038/nature11119 Nature, 2012, vol. 485, p. 635-641 http://dx.doi.org/10.1038/nature11119 cc-by-nc-sa (c) The Tomato Genome Consortium, 2012 http://creativecommons.org/licenses/by-nc-sa/3.0/es/ info:eu-repo/semantics/openAccess 7 p. application/pdf application/pdf Nature Publishing Group Articles publicats en revistes (Bioquímica i Biomedicina Molecular)
