TLDR
Phylogenetic analysis using 31 Vg sequences from 25 insect species reflects, in general, the current phylogenies of insects, suggesting that Vgs are still phylogenetically bound, although a divergence exists among them.About:

TL;DR: The genome and stage-specific transcriptomes of the dampwood termite Zootermopsis nevadensis (Blattodea) are sequence and similarities in the number and expression of genes related to caste determination mechanisms support a hypothesized epigenetic regulation of caste differentiation.

Predictive markers of honey bee colony collapse
TL;DR: The data show that DWV, Nosema ceranae, Varroa destructor and Vitellogenin can be predictive markers for winter colony losses, but their predictive power strongly depends on the season.

Insect vitellogenin/lipophorin receptors: molecular structures, role in oogenesis, and regulatory mechanisms.
Muhammad Tufail,Makio Takeda +1 more
TL;DR: The expression studies clearly demonstrate that insect VgRs are ovary-bound receptors of the LDLR family as compared to LpRs, which are transcribed in a wide range of tissues including ovary, fat body, midgut, brain, testis, Malpighian tubules, and muscles.
Journal ArticleDOI
Transfer of Immunity from Mother to Offspring Is Mediated via Egg-Yolk Protein Vitellogenin.
TL;DR: A molecular explanation for trans-generational immunity in insects and a previously undescribed role for vitellogenin are revealed, which is distributed widely in oviparous species, as the carrier of immune-priming signals.
Journal ArticleDOI
Juvenile hormone regulation of vitellogenin synthesis in the red flour beetle, Tribolium castaneum.
TL;DR: RNA interference (RNAi)-aided knock-down in the expression of these genes showed that both JH and 20E were required for Vg gene expression, suggesting that JH is required for vitellogenin synthesis in the fat body and20E influences Vg synthesis through its action on oocyte maturation.

Characterization of the solubilized mosquito vitellogenin receptor
TL;DR: During egg maturation, the number of receptor binding sites in ovaries correlated with the rate of Vg uptake and peaked between 24–30 h after which it reduced to no binding by 48 h post blood meal.
Journal ArticleDOI
Induction of vitellogenin synthesis in Locusta migratoria by the juvenile hormone analog, pyriproxyfen
TL;DR: The parallel responses to pyriproxyfen and to methoprene in several different tests suggest that, despite their different structures, both compounds share the same primary mode of action, which is believed to correspond to that of natural juvenile hormone.

Complete nucleotide sequence of the vitellogenin mRNA from the gypsy moth: Novel arrangement of the subunit encoding regions
Shiv Hiremath,Kirsten Lehtoma +1 more
TL;DR: The complete nucleotide sequence of the gypsy moth VgmRNA is determined, which shows that its structure is significantly different from VgmRNAs in other systems.

A simple and rapid method for cloning insect vitellogenin cDNAs.
TL;DR: A simple and rapid method for cloning insect vitellogenin (Vg) cDNAs was successfully applied to the bean bug Plautia stali (Heteroptera), revealing three Vg genes.

The vitellogenin of Leucophaea maderae: Synthesis as a large phosphorylated precursor
Guy della-Cioppa,Franz Engelmann +1 more
TL;DR: It is speculated that the asymmetric pattern of vitellogenin and viteLLin subunit-phosphorylation is due to an uneven distribution of phosphoserine residues along the initial pre-Vg polypeptide chain.
