Hydnoroideae. parasitic plant, plant that obtains all or part of its nutrition from another plant (the host) without contributing to the benefit of the host and, in some cases, causing extreme damage to the host. The defining structural feature of a parasitic plant is the haustorium, a specialized organ that penetrates the host and forms a ...
Aug 20, 2018 · Parasitic plants attach and feed off other plants using a parasitic structure called a haustorium. The haustorium is a specialised multicellular organ homologous to a root, which penetrates a host, makes a vascular connection, and facilitates the transfer of nutrients and other molecules.
Apr 21, 2021 · Parasitic plants connect to the vasculature of a host plant and take part or all of the water, nutrients, and assimilates they need to complete their life cycle. Parasitic plants represent a unique model for the evolution of intra-kingdom parasitism with intriguing research questions such as how plants were able to evolve the ability to parasitize other plants.

Jan 1, 2004 · Here 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).
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome . All parasitic plants develop a specialized organ called the haustorium , which penetrates the host plant, connecting them to the host vasculature – either the xylem , phloem , or both. [ 1 ]
In contrast to most autotrophic plants, which produce carbohydrates from carbon dioxide using photosynthesis, parasitic plants obtain water and nutrients by parasitizing host plants. Many important crop plants are infested by these heterotrophic plants, leading to severe agricultural loss and reduced food security. Understanding how host plants perceive and resist parasitic plants provides ...
