Main conclusion Metabolites in  Rafflesia -infected and non-infected  Tetrastigma  were compared which may have applications in  Rafflesia  propagation. Benzylisoquinoline alkaloids, here reported for the first time in Vitaceae, were abundant in non-infected shoots and may be a form of defense. In  Rafflesia -infected shoots, oxylipins, which mediate immune response, were elevated. Endemic to the forests of Southeast Asia,  Rafflesia  (Rafflesiaceae) is a genus of holoparasitic plants producing the largest flowers in the world, yet completely dependent on its host, the tropical grape vine,  Tetrastigma .  Rafflesia  species are threatened with extinction, making them an iconic symbol of plant conservation. Thus far, propagation has proved challenging, greatly decreasing efficacy of conservation efforts. This study compared the metabolites in the shoots of  Rafflesia -infected and non-infected  Tetrastigma loheri  to examine how  Rafflesia  infection affects host metabolomics and elucidate the  Rafflesia  infection process. Results from LC–MS-based untargeted metabolomics analysis showed benzylisoquinoline alkaloids were naturally more abundant in non-infected shoots and are here reported for the first time in the genus  Tetrastigma,  and in the grape family, Vitaceae. These metabolites have been implicated in plant defense mechanisms and may prevent a  Rafflesia  infection. In  Rafflesia -infected shoots, oxygenated fatty acids, or oxylipins, and a flavonoid, previously shown involved in plant immune response, were significantly elevated. This study provides a preliminary assessment of metabolites that differ between  Rafflesia -infected and non-infected  Tetrastigma  hosts and may have applications in  Rafflesia  propagation to meet conservation goals.
