Title Variation in secondary metabolites in a unique set of tomato accessions collected in Turkey

Keyword(s) Acetonitrile (Pubchem CID: 6342) - Formic acid (Pubchem CID: 284) provided by Merck (Frankfurter, Germany) - LC-MS grade methanol (Pubchem CID: 887) - Metabolomics - Multivariate analysis - Semi-polar phytochemicals - Tomato

In this study, 50 tomato landraces grown in Turkey were investigated in terms of their secondary metabolite profiles. Each accession was planted in 2016 and 2017 in 3 replicates in an open field. In this study, color, pH and brix of the fruit samples were measured and an unbiased LCMS-based metabolomics approach was applied. Based on Principal Components Analysis (PCA) and Hierarchical Cluster Analysis (HCA) of the relative abundance levels of >250 metabolites, it could be concluded that fruit size was the most influential to the biochemical composition, rather than the geographical origin of accessions. Results indicated substantial biodiversity in various metabolites generally regarded as key to fruit quality aspects, including sugars; phenolic compounds like phenylpropanoids and flavonoids; alkaloids and glycosides of flavour-related volatile compounds. The phytochemical data provides insight into which Turkish accessions might be most promising as starting materials for the tomato processing and breeding industries.
