Mistletoe has been used as the herbal medicine to treat hypertension, diabetes mellitus, inflammation, arthritis and viral infection. In this study, we evaluated the anti-inflammatory effect of extracts of branch from Taxillus yadoriki being parasitic in Neolitsea sericea (TY-NS-B) using in vitro model. TY-NS-B significantly inhibited LPS-induced secretion of NO and PGE2 in RAW264.7 cells. TY-NS-B was also observed to inhibit LPS-mediated iNOS COX-2 expression. In addition, TY-NS-B attenuated production of inflammatory cytokines such as TNF-α and IL-1β induced by LPS...

The mitochondrial oxidative phosphorylation (OXPHOS) system, which is based on the presence of five protein complexes, is in the very center of cellular ATP production. Complexes I to IV are components of the respiratory electron transport chain that drives proton translocation across the inner mitochondrial membrane. The resulting proton gradient is used by complex V (the ATP synthase complex) for the phosphorylation of ADP. Occurrence of complexes I to V is highly conserved in eukaryotes, with exceptions being restricted to unicellular parasites that take up energy-rich compounds from their hosts...

Parasitism is a life history strategy found across all domains of life whereby nutrition is obtained from a host. It is often associated with reductive evolution of the genome, including loss of genes from the organellar genomes [1, 2]. In some unicellular parasites, the mitochondrial genome (mitogenome) has been lost entirely, with far-reaching consequences for the physiology of the organism [3, 4]. Recently, mitogenome sequences of several species of the hemiparasitic plant mistletoe (Viscum sp.) have been reported [5, 6], revealing a striking loss of genes not seen in any other multicellular eukaryotes...

Specialized herbivorous insects have the ability to transition between host plant taxa, and considering the co-evolutionary history between plants and the organisms utilizing them is important to understanding plant insect interactions. We investigated the role of a pine tree parasite, dwarf mistletoe (Arceuthobium spp.) M. Bieb. Santalales: Viscaceae, in mediating interactions between Neophasia (Lepidoptera: Pieridae) butterflies and pine trees, the butterflies' larval hosts. Mistletoe is considered the butterflies' ancestral host, and the evolutionary transition to pine may have occurred recently...

Host specialization after host shifting is traditionally viewed as the pathway to speciation in parasitic plants. However, geographical and environmental changes can also influence parasite speciation, through hybridization processes. Here we investigated the impact of past climatic fluctuations, environment, and host shifts on the genetic structure and patterns of hybridization and gene flow between Psittacanthus calyculatus and P. schiedeanus, a Mesoamerican species complex. Using microsatellites (408 individuals), we document moderate genetic diversity but high genetic differentiation between widespread parental clusters, calyculatus in dry pine-oak forests and schiedeanus in cloud forests...

Coadaptation between mistletoes and birds captured the attention of Charles Darwin over 150 years ago, stimulating considerable scientific research. Here we used Loranthaceae, a speciose and ecologically important mistletoe family, to obtain new insights into the interrelationships among its hosts and dispersers. Phylogenetic analyses of Loranthaceae were based on a dataset of nuclear and chloroplast DNA sequences. Divergence time estimation, ancestral area reconstruction, and diversification rate analyses were employed to examine historical biogeography...

It has long been recognized that primary foundation species (FS), such as trees and seagrasses, enhance biodiversity. Among the species facilitated are secondary FS, including mistletoes and epiphytes. Case studies have demonstrated that secondary FS can further modify habitat-associated organisms ('inhabitants'), but their net effects remain unknown. Here we assess how inhabitants, globally, are affected by secondary FS. We extracted and calculated 2,187 abundance and 397 richness Hedges' g effect sizes from 91 and 50 publications, respectively...
