Host specificity in parasitic plants—perspectives from mistletoes
Host specificity has been investigated for centuries in mistletoes, viruses, insects, parasitoids, lice and flukes, yet it is poorly understood. Reviewing the numerous studies on mistletoe host specificity may contribute to our understanding of these plants and put into context the dynamics at work in root parasitic plants and animal parasites. The mechanisms that determine host specificity in ...
متن کاملDispersal, Germination and Survival of New Zealand Mistletoes (loranthaceae): Dependence on Birds
Mistletoes are stem hemiparasites, which grow on the branches of a host tree or shrub and take water, water-conducted nutrients and organic solutes from the host’s xylem. There are two major mistletoe families, Loranthaceae and Viscaceae. The Loranthaceae are principally Southern Hemisphere in distribution, with between 50 and 80 genera (Barlow, 1983). New Zealand has six native species in the ...
متن کاملAfrican mistletoes (Loranthaceae); ethnopharmacology, chemistry and medicinal values: an update.
Mistletoes of the Loranthaceae and Viscaceae are hemiparasitic plants and their preparations in the form of injectable extracts, infusions, tinctures, fluid extracts or tea bags are widely used in various cultures in almost every continent to treat or manage various health problems including hypertension, diabetes mellitus, inflammatory conditions, irregular menstruations, menopause, epilepsy, ...
متن کاملTwo Epiparasitic Species of Phoradendron (Viscaceae) from Honduras: one New and for the Other a Range Extension and Host Determination
A new species of Phoradendron, Ph. mathiasenii, is described, and a range extension and host are given for Ph. tikalense. Both species are from Honduras and grow as epiparasites, i.e., mistletoes parasitizing other mistletoes. The parasitic host for both epiparasitic species of Phoradendron is Psittacanthus angustifolius (Loranthaceae), which in turn is parasitic on the terrestrial host, Pinus ...
متن کاملReproductive ecology and isolation of Psittacanthus calyculatus and P. auriculatus mistletoes (Loranthaceae)
BACKGROUND Relationships between floral biology and pollinator behavior are important to understanding species diversity of hemiparasitic Psittacanthus mistletoes (c. 120 species). We aimed to investigate trait divergence linked to pollinator attraction and reproductive isolation (RI) in two hummingbird-pollinated and bird-dispersed Psittacanthus species with range overlap. METHODS We investi...
