Somatic fusion, also called protoplast fusion, is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both, a somatic hybrid. Hybrids have been produced either between the different varieties of the same species (e.g. between non-flowering potato plants and flowering potato plants) or between two different species (e.g. between wheat triticum and rye secale to produce Triticale).
Uses of somatic fusion include making potato plants resistant to potato leaf roll disease. Through somatic fusion, the crop potato plant Solanum tuberosum – the yield of which is severely reduced by a viral disease transmitted on by the aphid vector – is fused with the wild, non-tuber-bearing potato Solanum brevidens, which is resistant to the disease. The resulting hybrid has the chromosomes of both plants and is thus similar to polyploid plants. Somatic Hybridization was firstly introduced by Carlson in Nicotiana 'glauea'

Famous quotes containing the words somatic and/or fusion:
“Parents must not only have certain ways of guiding by prohibition and permission; they must also be able to represent to the child a deep, an almost somatic conviction that there is a meaning to what they are doing. Ultimately, children become neurotic not from frustrations, but from the lack or loss of societal meaning in these frustrations.”
—Erik H. Erikson (20th century)
“Sadism and masochism, in Freud’s final formulation, are fusions of Eros and the destructive instincts. Sadism represents a fusion of the erotic instincts and the destructive instincts directed outwards, in which the destructiveness has the character of aggressiveness. Masochism represents the fusion of the erotic instincts and the destructive instincts turned against oneself, the aim of the latter being self-destruction.”
—Patrick Mullahy (b. 1912)
