Is there a secondary/specialized metabolism in the genus Cuscuta and which is the role of the host plant?

Abstract

The parasitic plants from the genus Cuscuta have been studied from different perspectives, such as their phytochemistry, pharmacology, taxonomy, as weeds, and as a model plant for plant-plant interactions. This review attempts to discuss the host plants’ influence on the phytochemistry and pharmacology of parasitic plants like Cuscuta from the evidence that has been published until recent years in specialized literature and which has not been addressed in detail. Also, the relationship between haustorium development from the parasitic plant and its attachment to the host plant vascular system is discussed and related to the phytochemical and pharmacological information available. In addition, the genus Cuscuta’s main applications description in patents is also explored. Finally, some important recommendations are suggested for further studies in Cuscuta or any other parasitic plant. This state-of-the art about the genus Cuscuta can be a valuable source of organized information for those researchers developing projects in a great variety of aspects related to this genus.
