In western forest ecosystems of North America, numerous dwarf mistletoe species are considered to be serious forest-borne disease agents.
Severe dwarf mistletoe infection can result in a reduction in tree growth, premature tree mortality, reduced seed and cone development, reduced wood quality, and increase the susceptibility of the host tree to pathogen and/or insect attack. Most of the commercially important conifers in western North America are parasitized by one or more dwarf mistletoes.
The interaction between dwarf mistletoes and their host can be generalized as a source-to-sink relationship. Dwarf mistletoes derive the majority of their nutrition from the host’s vascular tissues. Dwarf mistletoes have a root-like system, composed of primary and secondary haustoria, which invade, but do not injure, both the xylem and phloem of the host. Because this root-like endophytic system is not soil-borne, dwarf mistletoes are solely dependent on their host for water.
