Use of biotechnological methods for the production of interspecific somatic hybrids between wild species of the genus Solanum of the series Etuberosa and Pinnatisecta and the cultivated potato for the analysis of novel glykoalkaloids. Subproject: Chemica
Description:
The wild potato species of Solanum are a valuable genetic resource for broadening the genetic diversity of cultivated potato. The aim of the project is to investigate biosythesis of novel glykoalkaloids (GAs) between S. tuberosum and wild Solanum species. These compounds are interesting in terms of their pharmaceutical activity, influence on human health, and plant protection. Through combinatorial biochemistry hybrids between closely or more distantly related species may synthesise structurally novel molecules. It is expected that an enzyme with a certain substrate specificity isolated from one plant might encounter new but related substrates when introduced into another plant. It should be possible to produce new chemical structures never found earlier in nature. Several experimental data using somatic hybrids between S. tuberosum and S. brevidens support the feasibility of this approach. Somatic hybrids are produced between wild species of the genus Solanum, series Etuberosa and Pinnatisecta and cultivated potato. Protoplast fusion allows the combination of genomes between plants of sexually incompatible species which are not possible to be produced in conventional breeding. Because of the level of GAs this plant material is interesting for those analyses.
