Characterization of Vitellogenin and Vitellogenin Receptor of Conopomorpha sinensis Bradley and Their Responses to Sublethal Concentrations of Insecticide

open access: yesFrontiers in Physiology, 2018
Conopomorpha sinensis Bradley is the dominant borer pest of Litchi chinesis and Euphoria longan. Current management of C. sinensis relies upon insecticide application to adult moths.

bmo-miR-2739 and the novel microRNA miR-167 coordinately regulate the expression of the vitellogenin receptor in Bombyx mori oogenesis

Development, 2020
Vitellogenin receptors (VgRs) play crucial roles in oogenesis by mediating endocytosis of vitellogenin and other nutrients in ovipara. We conducted small RNA sequencing and screening with a luciferase reporter system, and found that bmo-miR-2739 and a ...

Molecular characteristics of insect vitellogenins and vitellogenin receptors

Insect Biochemistry and Molecular Biology, 1998
The recent cloning and sequencing of several insect vitellogenins (Vg), the major yolk protein precursor of most oviparous animals, and the mosquito Vg receptor (VgR) has brought the study of insect vitellogenesis to a new plane. Insect Vgs are homologous to nematode and vertebrate Vgs.

The role of Vitellogenin in the transfer of immune elicitors from gut to hypopharyngeal glands in honey bees (Apis mellifera).

Journal of insect physiology, 2019
Female insects that survive a pathogen attack can produce more pathogen-resistant offspring in a process called trans-generational immune priming. In the honey bee (Apis mellifera), the egg-yolk precursor protein Vitellogenin transports fragments of ...

Determination of locust vitellogenin by radioimmunoassay with [3H]propionyl-vitellogenin

General and Comparative Endocrinology, 1983
A simple procedure for radiolabeling of locust vitellogenin is described. This procedure involves coupling of [3H]propionyl succinimidate to purified vitellogenin with high yield and specific activity. Using this radiolabeled analog, a specific and sensitive radioimmunoassay was developed for determining locust vitellogenin content, with a lower ...

Honeybee (Apis cerana) vitellogenin acts as an antimicrobial and antioxidant agent in the body and venom

Developmental and Comparative Immunology, 2018
Honeybee (Apis mellifera) egg‐yolk protein vitellogenin (Vg) plays roles in immunity, antioxidation, and life span beyond reproduction, but it also acts as an allergen Api m 12 in venom. Here we established antimicrobial and antioxidant roles of honeybee

Levels of the endosymbiont Rickettsia in the whitefly Bemisia tabaci are influenced by the expression of vitellogenin

Insect molecular biology (Print), 2019
Bacterial endosymbionts play essential roles in the biology of their arthropod hosts by interacting with internal factors in the host. The whitefly Bemisia tabaci is a worldwide agricultural pest and a supervector for more than 100 plant viruses.

A Vitellogenin Antibody in Honey Bees (Apis mellifera): Characterization and Application as Potential Biomarker for Insecticide Exposure

Environmental Toxicology and Chemistry, 2019
The insect yolk precursor vitellogenin is a lipoglycoprotein synthesized and stored in the fat body and secreted into the hemolymph. In honey bees, vitellogenin displays crucial functions in hormone signaling, behavioral transition of nurse bees to ...
