Data from: Tales from the crypt: a parasitoid manipulates the behaviour of its parasite host

Kelly L. Weinersmith, Sean M. Liu, Andrew A. Forbes & Scott P. Egan
There are many examples of apparent manipulation of host phenotype by parasites, yet few examples of hypermanipulation—where a phenotype-manipulating parasite is itself manipulated by a parasite. Moreover, few studies confirm manipulation is occurring by quantifying whether the host's changed phenotype increases parasite fitness. Here we describe a novel case of hypermanipulation, in which the crypt gall wasp Bassettia pallida (a phenotypic manipulator of its tree host) is manipulated by the parasitoid crypt-keeper wasp Euderus set,...

Data from: Genetic differentiation associated with host plants and geography among six widespread species of South American Blepharoneura fruit flies (Tephritidae)

Kristina Ottens, Isaac S. Winkler, Matthew L. Lewis, Sonja J. Scheffer, Gessica A. Gomes-Costa, Marty A. Condon, Andrew A. Forbes, G. A. Gomes-Costa, K. Ottens, A. A. Forbes, M. L. Lewis & S. J. Scheffer
Tropical herbivorous insects are astonishingly diverse and many are highly host-specific. Much evidence suggests that herbivorous insect diversity is a function of host-plant diversity; yet, the diversity of some lineages exceeds the diversity of plants. Although most species of herbivorous fruit flies in the Neotropical genus Blepharoneura are strongly host-specific (they deposit their eggs in a single host plant species and flower sex), some species are collected from multiple hosts or flowers and these may...

Data from: Genetic variation for mitochondrial function in the New Zealand freshwater snail Potamopyrgus antipodarum

Joel Sharbrough, Jennifer L. Cruise, Megan Beetch, Nicole M. Enright, Maurine Neiman, Nicole M Enright & Jennifer L Cruise
The proteins responsible for mitochondrial function are encoded by two different genomes with distinct inheritance regimes, rendering rigorous inference of genotype–phenotype connections intractable for all but a few model systems. Asexual organisms provide a powerful means to address these challenges because offspring produced without recombination inherit both nuclear and mitochondrial genomes from a single parent. As such, these offspring inherit mitonuclear genotypes that are identical to the mitonuclear genotypes of their parents and siblings and...

Data from: De novo transcriptome characterization of a sterilizing trematode parasite (Microphallus sp.) from two species of New Zealand snails

Laura Bankers & Maurine Neiman
Snail-borne trematodes represent a large, diverse, and evolutionarily, ecologically, and medically important group of parasites, often imposing strong selection on their hosts and causing host morbidity and mortality. Even so, there are very few genomic and transcriptomic resources available for this important animal group. We help to fill this gap by providing transcriptome resources from trematode metacercariae infecting two congeneric snail species, Potamopyrgus antipodarum and P. estuarinus. This genus of New Zealand snails has gained...

Data from: Conformational dynamics in TRPV1 channels reported by an encoded coumarin amino acid

Ximena Steinberg, Marina A. Kasimova, Deny Cabezas-Bratesco, Jason D. Galpin, Ernesto Ladron-De-Guevara, Federica Villa, Vincenzo Carnevale, Leon Islas, Christopher A. Ahern, Sebastian Brauchi, Jason D Galpin, Christopher A Ahern, Marina A Kasimova & Sebastian E Brauchi
TRPV1 channels support the detection of noxious and nociceptive input. Currently available functional and structural data suggest that TRPV1 channels have two gates within their permeation pathway: one formed by a ′bundle-crossing′ at the intracellular entrance and a second constriction at the selectivity filter. To describe conformational changes associated with channel gating, the fluorescent non-canonical amino acid coumarin-tyrosine was genetically encoded at Y671, a residue proximal to the selectivity filter. Total internal reflection fluorescence microscopy...
