Ecology of box mistletoe Amyema miquelii dispersal in pink gum Eucalyptus fasciculosa woodlands.
The proliferation of box mistletoe Amyema miquelii in eucalypt woodlands of south-eastern Australia may have resulted from the suppression of canopy fires, a reduction in herbivory by possums, and through environmental change, an improvement in conditions for mistletoe dispersal and establishment. …

The dispersal of three mistletoe species by birds in the Loskop Dam Nature Reserve
The mistletoe species Tapinanthus leendertziae, T. natalitius and Viscum combreticola and their avian dispersal agents were studied in the field during February 1977 - May 1978. The study was carried out in seven different plant communities. Year-round surveys were made of the reproductive …

Dwarf Mistletoe And Its Effect Upon The Growth Of Larch And Douglas Fir In Western Montana
Dwarf mistletoes are intolerant, dioecius seed plants belonging to the Loranthaceae family. Five species, Arceuthobium pussillum, A. americanum, A, douglasii, A. vaginatum, and A. campylopodum have been recognized in North America. All of them are restricted to coniferous hosts. The aerial portions …

Reciprocal Transplant and Machine Learning Study of Oak Mistletoe on Three Host Oak Species in Santa Margarita, California
<p>At Santa Margarita Ranch, California, oak mistletoe (Phoradendron villosum) parasitizes valley oak and blue oak but cannot be found growing on coast live oak despite its abundance and ability to parasitize coast live oak in other areas. It seems as though this species of mistletoe is …

Composition, spatial abundance, co-occurrence and host preference of mistletoes in the Central highland savanna of Namibia
Aerial parasitic plants, commonly called mistletoes, are a polyphyletic group of organisms with a common evolutionary ancestor. This study was aimed at determining composition, spatial abundance within hosts, co-occurrence and host preference of mistletoes in the central highland savannas. The …

Radial growth patterns of jack pine in relation to climate, moisture availability, and dwarf mistletoe infection in the Boreal Plains Ecozone of Saskatchewan, Canada
… and range contractions. Lodgepole pine dwarf mistletoe (Arceuthobium americanum) (DM) is a host specific, parasitic plant of jack pine (Pinus banksiana) that affects resource allocation, water use, and growth. Despite being one of the most damaging pests to jack pine in the Canadian boreal …

Deciphering the chemistry of host-parasitic plants interactions using the UHPLC-q-TOF-MS and chemometrics
While mistletoes in the genus Viscum are extensively used in ethnomedicine globally, the parasitic nature of these plants can impact their secondary metabolite composition and thereby, influence their medicinal properties. The main objective of this study was to contrast the metabolome of Viscum …

Novel fusion proteins based on recombinant lectins for delivery of a cytotoxic peptide specifically to cancer cells
… recognized sugars are usually called lectins. Mistletoe lectin isoform I (MLI), from Viscum album, is an example which has strong binding affinity for sialic acids especially α2,6 sialic acid.In the present study, mistletoe lectin isoform I chain B (MLB) was targeted through conducting …

Seed dispersal in South African trees: with a focus on the megafaunal fruit and their dispersal agents
… Vertebrate dispersers range in size from 5g mistletoe birds (Dicaeidae) to 7,500,000g elephants (Elephantidae). The range and distribution of frugivore sizes is not uniform across ecosystems or geographical regions (Mack, 1993). These differences, one might suspect would be mirrored in the …
