Parasitic flowering plants
WebHere we define a parasitic plant as an angiosperm (flowering plant) that directly attaches to another plant via a haustorium. A haustorium is a specialized structure that forms a morphological and physiological link between the parasite and host ( Figure 2) (Kuijt 1969, Yoshida et al. 2016). WebAmong flowering plants, the most widespread form of parasitism is characterized by the development of an intrusive organ called the haustorium, which absorbs water and nutrients from the host. Despite this functionally unifying feature of parasitic plants, haustoria are not homologous structures; they have evolved 12 times independently.
