text: Genetic evidence has now shown that Linnaeus was correct to put the tomato in the genus Solanum, making Solanum lycopersicum the correct name. Both names, however, will probably be found in the literature for some time. Two of the major reasons for considering the genera separate are the leaf structure (tomato leaves are markedly different from any other Solanum), and the biochemistry (many of the alkaloids common to other Solanum species are conspicuously absent from the tomato). On the other hand, hybrids of tomato and diploid potato can be created in the lab by somatic fusion, and are partially fertile, providing evidence of the close relationship between these species.
  Genetics and genetic modification
  Genome
  An international consortium of researchers from 10 countries, began sequencing the tomato genome in 2004. A prerelease version of the genome was made available in December 2009. The complete genome for the cultivar Heinz 1706 was published on 31 May 2012 in Nature. The latest reference genome published in 2021 had 799 MB and encodes 34,384 (predicted) proteins, spread over 12 chromosomes.
  Genetic modification
  Since many other fruits, like strawberries, apples, melons, and bananas share the same characteristics and genes, researchers stated the published genome could help to improve food quality, food security and reduce costs of all of these fruits.
  The first commercially available genetically modified food was a tomato called Flavr Savr, which was engineered to have a longer shelf life. However, it is no longer commercially available. Scientists are continuing to develop tomatoes with new traits not found in natural crops, such as increased resistance to pests or environmental stresses or better flavor.
