Structural diversity of arthropod venom toxins

, 2018
Arthropods are a diverse and ancient group of invertebrate animals, which constitute approximately 75-85% of all known species on earth. Many arthropod species, such as spiders, scorpions and even some crustaceans, contain venoms that can be very complex,

Is quinoa‐farming sustainable in marginal environments? Social, economical and environmental aspects

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Quinoa (Chenopodium quinoa Willd.) is an Andean grain crop introduced as a novel crop to many parts of the world in recent years. Recognized for nutritious seeds and high abiotic stress tolerance, it has been promoted as an element of climate‐resilient agriculture, particularly in marginal environments.

Neuroparsins, a family of conserved arthropod neuropeptides

, 2007
Different neuroparsin variants were initially identified as anti-gonadotropic peptides from the pars intercerebralis-corpora cardiaca complex of the migratory locust, Locusta migratoria, and further studies revealed the pleiotropic activities of these ...

Characterizing bacteriophage proteins that hijack arthropod reproduction

, 2020
Wolbachia are maternally-inherited symbionts that cause cytoplasmic incompatibility (CI). Dual expression of the two phage WO genes cifA and cifB in males causes CI, while expression of cifA in females rescues CI.

Fruit use and fruit processing by euphonias, specialized avian frugivores

Oikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

Chitosan‐protected dsRNA increases efficacy against Helicoverpa armigera without compromising biosafety for pollinators

Pest Management Science, EarlyView.
Chitosan/tripolyphosphate/double‐stranded RNA (dsRNA) nanoparticles enhance RNA interference efficacy of orally delivered dsRNA against Helicoverpa armigera. Nanoparticles reduce the LC50 and do not cause deleterious effects or toxicity on beneficial insects.

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

Pest Management Science, EarlyView.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

Ice Nucleation Properties of Ice-binding Proteins from Snow Fleas

Biomolecules, 2019
Ice-binding proteins (IBPs) are found in many organisms, such as fish and hexapods, plants, and bacteria that need to cope with low temperatures. Ice nucleation and thermal hysteresis are two attributes of IBPs.

Molecular approaches to the study of ecdysozoan evolution

, 2010
The Ecdysozoa is a large clade of animals comprising the vast majority of living species and some of the most studied invertebrate models, including fruitflies and nematodes.
