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:

Journal ArticleDOI
Massively parallel pyrosequencing-based transcriptome analyses of small brown planthopper (Laodelphax striatellus), a vector insect transmitting rice stripe virus (RSV).
F. Zhang,Hongyan Guo,Huajun Zheng,Tong Zhou,Yijun Zhou,Shengyue Wang,Rongxiang Fang,Wei Qian,Xiaoying Chen +8 more
TL;DR: Comparative genomic analysis revealed that L. striatellus encodes similar innate immunity regulatory systems as other insects, such as RNA interference, JAK/STAT and partial Imd cascades, which might be involved in defense against viral infection.

Molecular characterization and RNA interference analysis of vitellogenin receptor from Nilaparvata lugens (Stål)
Kai Lu,Yinghua Shu,Jialiang Zhou,Xiaoyi Zhang,Xinyu Zhang,Ming-Xiao Chen,Qiong Yao,Qiang Zhou,Wenqing Zhang +8 more
TL;DR: The results suggest that VgR is critical for Vg uptaking of oocytes and it plays an important role in insect fecundity.

Transovarial transmission of a plant virus is mediated by vitellogenin of its insect vector.
Yan Huo,Wenwen Liu,F. Zhang,Xiaoying Chen,Li Li,Qifei Liu,Yijun Zhou,Taiyun Wei,Rongxiang Fang,Xifeng Wang +9 more
TL;DR: Rice stripe virus–planthopper system is used as a model to investigate the mechanism of transovarial transmission and the central role of vitellogenin (Vg) of L. striatellus is demonstrated, which shows how viruses can use existingtransovarial transportation systems in insect vectors for their own purposes.

Regulation of vitellogenin genes in insects
TL;DR: The role of Vg genes as a target of endocrine disruptors will be addressed, and the molecular mechanism of Vn gene regulation will be discussed, which is the main nutritional reserve for the developing embryo.

Insulin-Like Peptides: Structure, Signaling, and Function
TL;DR: Of the diverse invertebrate groups, accumulated knowledge of ILP endocrinology is the deepest and broadest for insects, and essentially all of the proteins that make up the mechanisms for ILP processing, secretion, and signaling are remarkably similar to those of vertebrates, in effect conserving the pleiotropic effects of ILPs between insects and vertebrates.

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.
