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:

Flowers promote ovarian development and vitellogenin gene expression in Apolygus lucorum (Heteroptera: Miridae)
TL;DR: Host plant flowers significantly facilitate ovarian development and Vg gene expression of A. lucorum adults, suggesting that the herbivore might respond positively to the presence of host plant flowers as food.
Journal ArticleDOI
Insect Bacterial Symbiont-Mediated Vitellogenin Uptake into Oocytes To Support Egg Development.
TL;DR: It is reported that leafhopper vitellogenin recognizes and binds a surface channel molecule (porin) on the envelope of obligate bacterial symbiont Nasuia, which potentially induces the opening of porin channels for Vg to access the cytoplasm of NasUia.

Search for Nutritional Fitness Traits in a Biological Pest Control Agent Harmonia axyridis Using Comparative Transcriptomics.
TL;DR: The Vg supplement has increased activities of digestive enzymes and related genes expression in H. axyridis, and the transcript level of digestive enzyme genes were much higher in adults fed on diet supplemented with Vg compared with that of the control.

Two alternative splicing variants of a sugar gustatory receptor modulate fecundity through different signalling pathways in the brown planthopper, Nilaparvata lugens.
TL;DR: Cloned NlGr10a and Nlgr10b, two alternative splicing variants of a sugar gustatory receptor gene in the brown planthopper (BPH), Nilaparvata lugens, were cloned and found that their ligands were different by calcium imaging assay, broadening the understanding of the difference in the ligands and functions of alternative splice variants of gustatory receptors in insects.

Triazophos-induced vertical transmission of rice stripe virus is associated with host vitellogenin in the small brown planthopper Laodelphax striatellus
TL;DR: The results indicated that triazophos-induced RSV vertical transmission was associated with Vg, and this work will facilitate further elucidate sublethal doses of insecticides-mediated effects and develop new strategies for pest control.

Mammalian subtilisins: The long-sought dibasic processing endoproteases
TL;DR: After many years of searching for the enzymes responsible for cleavage of mammalian proproteins and prohormones at sites comprised of pairs of basic amino acid residues (“dibasic sites”), the solution to this enigma of cell biology appears to be in sight.

Accumulation of yolk proteins in insect oocytes
TL;DR: In insects, accumulation of yolk, or vitellogenesis, is a heterosynthetic pro cess, in which an extraovarian tissue, the fat body, produces yolk protein precursors, and the role of endocytosis in yolk deposition in insect oocytes is implicated.
