“…3). A negative co-occurrence pattern in mistletoe species that specialize on distinct suites of host species has been also reported in North America, New Zealand and Australia (Hawksworth and Wiens 1972; Blick and Burns 2009; Blick et al 2012). Similarly, Fadini (2011) showed that three congeneric and sympatric mistletoe species ( Psittacanthus biternatus , P. eucalyptifolius and P. plagiophyllus ) specialize on different host species in the Amazon.…”

“…A pattern of non-overlap in mistletoe primary host use may be indicative of competitive exclusion and could contribute to a geographic mosaic of mistletoe–host interactions. Such a geographic mosaic could ultimately determine patterns of host specificity in mistletoes ( sensu Blick and Burns 2009). Further investigation is warranted to quantify the degree of competition among mistletoe species and to determine the mechanisms that drive such interactions.…”

Mistletoes are very fascinating parasitic plants. For centuries, people have been kissing under mistletoes during Christmas celebrations. Unlike most common plants, mistletoes grow on the branches of other plants and rely on these "host" plants for water and nutrients. Scientists have been trying to understand why parasitic plants differ in the number of host species parasitised. Like many parasitic plants, mistletoes can parasitise several plant species or only use one or far fewer species. This review contributes to the current broad understanding of parasite-host interactions using mistletoe as a case study. Future research needs are also highlighted.

“…Th e fi rst step toward improving our understanding of mistletoe-host interactions is to determine the pattern of host specifi city on various spatial scales (Norton & Carpenter 1998;Blick & Burns 2009, Arruda et al 2012. Empirical data show that some species of mistletoe that locally specialize on certain host species (e.g., Psittacanthus plagiophyllus on Anacardium occidentale L.; Fadini 2011) are generalists on a regional scale (Caires & Proença 2008).…”

Two mistletoes are too many?: Interspecific occurrence of mistletoes on the same host tree

et al. 2013

Mistletoe can have a major impact on the fi tness of the host plant. If there is more than one species of mistletoe on the same host tree, the overall impact might be amplifi ed. We report the occurrence of more than one species of mistletoe on the same host tree. Although it is not a rule in the fi eld, to our knowledge, there have been no studies of this topic. In most cases, two species of mistletoe were recorded on the same host tree, although we recorded three species of mistletoe on one occasion. Th is demonstrates that diff erent species of mistletoe can be compatible with the same host species. Th erefore, compatibility (structural and physiological) might be an important factor for the occurrence of mistletoe. Recent studies have shown that if the mistletoe does not "recognize" the host species, the deposited seeds will germinate but the haustorium will not penetrate the host branch. Th is is probably the primary mechanism in the establishment of more than one species of mistletoe on the same host, which can trigger a cascade of harmful eff ects for the host species.

“…Sack and Holbrook (2006) represent the plant as a simplified electronic circuit based on water transport capacity, a network structure relevant for microbes that use the plant vascular system. Skirting the within-plant scale, network models have also been applied to microbial movement between individual plant hosts Lamour et al 2007;Moslonka-Lefebvre et al 2011), to evaluate the coexistence of plants and epiphytes (Blick and Burns 2009), and to model mycorrhizal networks (Southworth et al 2005).…”

Information networks for disease: commonalities in human management networks and within-host signalling networks

Network models of human epidemics can often be improved by including the effects of behaviour modification in response to information about the approach of epidemics. Similarly, there are opportunities to incorporate the flow of information and its effects in plant disease epidemics in network models at multiple scales. (1) In the case of human management networks for plant disease, each node of a network has four main components: plant communities, microbial communities, human information (among researchers, extension agents, farmers, and other stakeholders), and environmental conditions, along with their interactions. The links between nodes, representing the rate of movement between them, have three parts: the rates for plant materials, the rates for microbes, and the rates for information. Network resilience for information flow is an important goal for such systems. Game theory can provide insights into how human agents decide how to invest their efforts in strengthening information networks, and how policies can support more resilient networks. (2) For the case of withinplant signalling networks, each node has a comparable set of four main components: plant signals (often in the form of phytohormones) and development status, microbial communities and plant disease status, microbial signals (often in the form of quorum sensing molecules), and micro-environmental conditions, along with their interactions. In effect, human information is replaced by plant signals and microbial signals in this second model. The links between nodes have three parts: the rates for microbes, the rates for microbial signals (which may move separately from the microbes, themselves), and the rates for plant signals. Understanding how to enhance adaptive plant signalling networks and microbial signalling networks that support plant productivity, and disrupt microbial signalling networks that contribute to pathogenicity, will be an important step for improved disease management.
