Temperature Alters Specificity in a Host–Parasite Interaction [PDF]
The Red Queen Hypothesis proposes that genetic variation is maintained in populations through antagonistic coevolution of hosts and parasites. A major assumption of the Red Queen Hypothesis is tight genetic specificity for infection. However, it has been

Root-knot nematode (RKN), Meloidogyne incognita, is one of the most lingering and difficult to manage pest of black pepper in India. The options for controlling RKN are becoming increasingly limited due to the potential risk involved in environmental and

Exploring the mechanisms of host-specificity of a hyperparasitic bacterium (Pasteuria spp.) with potential to control tropical root-knot nematodes (Meloidogyne spp.): insights from Caenorhabditis elegans [PDF]
Plant-parasitic nematodes are important economic pests of a range of tropical crops. Strategies for managing these pests have relied on a range of approaches, including crop rotation, the utilization of genetic resistance, cultural techniques, and since ...

Ectopical expression of bacterial collagen-like protein supports its role as adhesin in host–parasite coevolution [PDF]
For a profound understanding of antagonistic coevolution, it is necessary to identify the coevolving genes. The bacterium Pasteuria and its host, the microcrustacean Daphnia, are a well-characterized paradigm for co-evolution, but the underlying genes ...

QTL study reveals candidate genes underlying host resistance in a Red Queen model system. [PDF]
Specific interactions of host and parasite genotypes can lead to balancing selection, maintaining genetic diversity within populations. In order to understand the drivers of such specific coevolution, it is necessary to identify the molecular ...

The parasites of my rival are my friends [PDF]
The competitive exclusion principle asserts that two species cannot stably coexist in the same habitat. However, the presence of a parasite can facilitate temporary coexistence between two host species occupying the same habitat.

The visual ecology of selective predation: Are unhealthy hosts less stealthy hosts? [PDF]
Predators can strongly influence disease transmission and evolution, particularly when they prey selectively on infected hosts. Although selective predation has been observed in numerous systems, why predators select infected prey remains poorly ...

Imaging flow cytometry enables label-free cell sorting of morphological variants from populations of the unculturable bacterium Pasteuria ramosa [PDF]
Bacterial populations often display remarkable morphological heterogeneity. Fluorescence-activated cell sorting (FACS) is an important tool for understanding this diversity. FACs allows researchers to obtain pure samples of each morphological variant (or

Peer review of the pesticide risk assessment of the active substance Pasteuria nishizawae Pn1
The conclusions of EFSA following the peer review of the initial risk assessments carried out by the competent authority of the rapporteur Member State, Denmark, for the pesticide active substance Pasteuria nishizawae Pn1 are reported. The context of the

A common multi-host parasite shows genetic structuring at the host species and population levels [PDF]
Although individual parasite species commonly infect many populations across physical space as well as multiple host species, the extent to which parasites traverse physical and phylogenetic distances is unclear.
