Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

An Extreme Case of Plant–Insect Codiversification: Figs and Fig-Pollinating Wasps [PDF]

Systematic Biology, 2012
Se cree que la especiación en insectos fitófagos a menudo se debe a la colonización de nuevas plantas huésped, porque las radiaciones de los linajes de plantas e insectos son típicamente asíncronas. Las recientes comparaciones filogenéticas han respaldado este modelo de diversificación tanto para insectos herbívoros como para polinizadores ...

The obligate fig-pollinator family Agaonidae in Germany (Hymenoptera, Chalcidoidea) [PDF]

Deutsche Entomologische Zeitschrift
All native and many cultivated fig plants are pollinated by representatives of the family Agaonidae (fig wasps), which are specialised, secondarily phytophagous relatives of parasitoid wasps that evolved an obligate mutualism with fig trees.

Advancing Therapies for Mycobacterial Diseases: From Small Molecules to Host‐Directed Strategies

Medicinal Research Reviews, EarlyView.
ABSTRACT The global burden of multidrug‐resistant tuberculosis (MDR‐TB) and the rising incidence of nontuberculous mycobacterial (NTM) infections highlight the urgent need for innovative therapeutic strategies. Current treatments are prolonged, toxic, and increasingly compromised by resistance and limited diagnostic capacity.

Genomes of Wiebesia Fig Wasps Reveal the Adaptation and Codiversification in the Fig–Fig Wasp Mutualism

Genome Biology and Evolution
Abstract Figs and fig wasps represent one of the most intimate examples of plant–pollinator coevolution. As figs diversified into geographically isolated populations, both figs and fig wasps underwent selective pressures driven by local adaptation and coevolution.

A plant–pollinator invasional meltdown: the Japanese pagoda tree Styphnolobium japonicum facilitates the invasion of the giant resin bee Megachile sculpturalis

Oikos, EarlyView.
An invasional meltdown can occur when a non‐native species facilitates the spread of another non‐native species in the invaded area, increasing its likelihood of survival or its ecological impact. Plant–pollinator systems pose an exceptional study system to test this concept, which remains poorly known.

Heterogeneous preferences for use and non‐use values provided by insects

People and Nature, EarlyView.
Abstract Public support is essential for reversing insect declines, yet conservation efforts often focus on instrumental values, particularly pollination and pest regulation, while overlooking the many and varied cultural ecosystem services that may underpin broader public support for conservation.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Diversification and spatial structuring in the mutualism between Ficus septica and its pollinating wasps in insular South East Asia

BMC Evolutionary Biology, 2017
Background Interspecific interactions have long been assumed to play an important role in diversification. Mutualistic interactions, such as nursery pollination mutualisms, have been proposed as good candidates for diversification through co-speciation ...
