Molecular evolution of bumble bee vitellogenin and vitellogenin‐like genes [PDF]

Ecology and Evolution, 2021
AbstractVitellogenin (Vg), a storage protein, has been significantly studied for its egg yolk precursor role in oviparous animals. Recent studies found that vitellogenin and its Vg‐like homologs were fundamentally involved in many other biological processes in social insects such as female caste differences and oxidative stress resilience.

Vitellogenin and Vitellogenin-Like Genes in the Brown Planthopper [PDF]

Frontiers in Physiology, 2019
Vitellogenin (Vg) is precursor of vitellin. Here, we identified a Vg (NlVg) and two Vg-likes (NlVg-like1 and NlVg-like2) in the brown planthopper, Nilaparvata lugens. Phylogenetic analyses showed that NlVg-like1 and NlVg-like2 are not clustered with the conventional insect Vgs associated with vitellogenesis.

Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

Integrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

PRY-1/Axin signaling regulates lipid metabolism in Caenorhabditis elegans. [PDF]

PLoS ONE, 2018
The nematode Caenorhabditis elegans constitutes a leading animal model to study how signaling pathway components function in conserved biological processes. Here, we describe the role of an Axin family member, PRY-1, in lipid metabolism.

Insect Bacterial Symbiont-Mediated Vitellogenin Uptake into Oocytes To Support Egg Development

mBio, 2020
Many insect species, such as aphids, leafhoppers, planthoppers, and whiteflies harbor obligate bacterial symbionts that can be transovarially transmitted to offspring through the oocytes of female insects.

Social exploitation of vitellogenin [PDF]

Proceedings of the National Academy of Sciences, 2003
Vitellogenin is a female-specific glucolipoprotein yolk precursor produced by all oviparous animals. Vitellogenin expression is under hormonal control, and the protein is generally synthesized directly before yolk deposition. In the honeybee ( Apis mellifera ), vitellogenin is not only ...

The molecular and structural characterization of two vitellogenins from the free-living nematode Oscheius tipulae. [PDF]

PLoS ONE, 2013
This paper describes the purification of yolk proteins, which are important for the reproduction of egg-laying animals, and the structural characterization of two vitellogenins, VT1 and OTI-VIT-6, of the nematode Oscheius tipulae. O.

Expression analysis of vitellogenins in the workers of the red imported fire ant (Solenopsis invicta) [PDF]

PeerJ, 2018
Vitellogenin has been proposed to regulate division of labor and social organization in social insects. The red imported fire ant (Solenopsis invicta) harbors four distinct, adjacent vitellogenin genes (Vg1, Vg2, Vg3, and Vg4).

Vitellogenins - Yolk Gene Function and Regulation in Caenorhabditis elegans

Frontiers in Physiology, 2019
Vitellogenins are a family of yolk proteins that are by far the most abundant among oviparous animals. In the model nematode Caenorhabditis elegans, the 6 vitellogenins are among the most highly expressed genes in the adult hermaphrodite intestine, which

Nutritional and reproductive signaling revealed by comparative gene expression analysis in Chrysopa pallens (Rambur) at different nutritional statuses. [PDF]

PLoS ONE, 2017
The green lacewing, Chrysopa pallens Rambur, is one of the most important natural predators because of its extensive spectrum of prey and wide distribution.
