摘要

Coffee plants contain well-known xanthines as caffeine. Three Coffea species grown in a controlled greenhouse environment were the focus of this research. Coffea arabica and C. canephora are two first principal commercial species and commonly known as arabica and robusta, respectively. Originating in Central Africa, C. anthonyi is a novel species with small leaves. The xanthine metabolites in flower, fruit and leaf extracts were compared using both targeted and untargeted metabolomics approaches. We evaluated how the xanthine derivatives and FQA isomers relate to the expression of biosynthetic genes encoding N- and O-methyltransferases. Theobromine built up in leaves of C. anthonyi because caffeine biosynthesis was hindered in the absence of synthase gene expression. Despite this, green fruits expressed these genes and they produced caffeine. Given that C. anthonyi evolved successfully over time, these findings put into question the defensive role of caffeine in leaves. An overview of the histolocalisation of xanthines in the different flower parts of Coffea arabica was also provided. The gynoecium contained more theobromine than the flower buds or petals. This could be attributed to increased caffeine biosynthesis before fructification. The presence of theophylline and the absence of theobromine in the petals indicate that caffeine is catabolized more in the petals than in the gynoecium.
