The defining structural feature of a parasitic plant is the haustorium, a specialized organ that penetrates the host and forms a vascular union between the plants. See how parasitic plants form vascular unions with hosts to compensate for an inability to photosynthesize Learn about several different species of parasitic plants.
- Cuscata. Cuscuta, also commonly known as dodder, has no roots or leaves and instead is identifiable by its yellow or orange stems which have a stringy, hair-like appearance as it is in the morning glory family.
- Mistletoe. While mistletoe may be commonly associated with Christmas kisses, it's also a parasite. Mistletoe, a group of plants in the order Santalales, are found around the world.
- Australian Christmas tree (Nuytsia floribunda) Another festive entry, the Australian Christmas tree (Nuytsia floribunda) can photosynthesise but sometimes steals water from neighbouring plants.
- Ghost plant (Monotropa uniflora) The ghost plant (Monotropa uniflora) is a member of the heather family. It lacks chlorophyll, which is the reason for its distinctive white hue.
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 ]
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 · A prime example is the coordination of the parasitic plant lifecycle with that of the host, aided by a number of host detection/host response mechanisms that have evolved in parasitic plant species. In the update by Brun et al. (2021) , the molecular mechanisms underlying two of these—host-dependent seed germination and haustorium formation—are reviewed.

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 ...
