What is a mistletoe plant?

Mistletoe is the English common name for most obligate hemiparasitic plants in the order Santalales. They are attached to their host tree or shrub by a structure called the haustorium, through which they extract water and nutrients from the host plant. Their parasitic lifestyle have led to some dramatic changes in their metabolism.

What is mistletoe and why is it bad for You?

Mistletoe is a plant that grows parasitically on trees. Mistletoe can cause Witches’-broom, a symptom of a disease that results in clusters of weak shoots, in the host tree. One way to harvest mistletoe is to climb high in the tree to get the clusters; another way is to blast them out with a shotgun. How’s that for festive? It gets worse.

Does mistletoe kill the host plant?

Mistletoe species grow on a wide range of host trees, some of which experience side effects including reduced growth, stunting, and loss of distal branches that bear individuals. A heavy infestation may also kill the host plant. Viscum album successfully parasitizes more than 200 tree and shrub species.

Do mistletoe plants photosynthesize?

Not only do they photosynthesize actively, but a heavy infestation of mistletoe plants may take over whole host tree branches, sometimes killing practically the entire crown and replacing it with their own growth. In such a tree the host is relegated purely to the supply of water and mineral nutrients and the physical support of the trunk.

Is the mistletoe plant poisonous?

But as sweet and innocent as the mistletoe holiday traditions are, the plant is much more of a taker than a giver. Beyond its glorious Christmastime use, the mistletoe plant in nature is a semi-parasitic plant. And one that in some instances, can even be deadly to its host.

How does mistletoe get stuck to a tree?

Depending on the species of mistletoe and the species of bird, the seeds are regurgitated from the crop, excreted in their droppings, or stuck to the bill, from which the bird wipes it onto a suitable branch. The seeds are coated with a sticky material called viscin. Some viscin remains on the seed and when it touches a stem, it sticks tenaciously.

Does mistletoe kill a tree?

Mistletoe does not normally kill a tree, but it can be a contributing factor in a tree’s loss if the tree has other problems. Mistletoe stays green in the winter when its host tree goes dormant, so if your elm looks like an evergreen tree this winter, you know you have a problem — utopia for a bird, but a plague for the elm.

What are the long-term effects of mistletoe on host plants?

Although the host plants response to mistletoe attack resembles the response to other biotic stresses, unlike short-term stressors, the effect of mistletoe attack is long-term and depends on the parasite load. Infection by mistletoe leads to water and nutrient stress of the host plant and deteriorates its healthy establishment and survival.

Is Mistletoe a parasitic plant?

Mistletoe grows wild in many parts of Europe and North America. It is a parasitic plant that draws the host tree’s carbohydrates into itself. This activity can reduce the health of the particular branch to which the mistletoe is attached and minimize fruit yield.

How does mistletoe spread from tree to tree?

Note that some species of mistletoe do produce a portion of their own food through photosynthesis because they have leaves. Mistletoe can affect a wide range of host plants and can spread to lower portions of a tree once it becomes established. It is also spread from tree to tree by birds, which feed on the seeds and deposit them in nearby trees.
