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:

The N-terminal subunit of vitellogenin in planthopper eggs and saliva acts as a reliable elicitor that induces defenses in rice
Jiamei Zeng,Wenfeng Ye,Wenhui Hu,Xiaochen Jin,Peng Kuai,Wen-Han Xiao,Yukun Jian,Ted C. J. Turlings,Yonggen Lou +8 more
TL;DR: It is found that the small N-terminal subunit of vitellogenins of the planthopper Nilaparvata lugens (NlVgN) triggers strong defense responses in rice plants when it enters the plant during feeding or oviposition by the insect.

Transcriptomic analysis reveals yolk accumulation mechanism from the hepatopancreas to ovary in the pacific white shrimp Litopenaeus vannamei
Zhi Li,Minyu Zhou,Yao Ruan,Xiaoli Chen,Chunhua Ren,Huanming Yang,Xin Zhang,Jinshang Liu,Huo Li,Lvping Zhang,Chaoqun Hu,Ting Chen,Xugan Wu +12 more
TL;DR: Solid evidence is provided that the hepatopancreas is the major exogenous vitellogenesis site for ovarian maturation of L. vannamei by transcriptomic analysis, which found that genes related to amino acid, carbohydrate and lipid metabolism were expressed at higher levels in the liver than in the ovary.
Molecular characterization, developmental expression and immunolocalization of clathrin heavy chain in the ovary of the American cockroach, Periplaneta americana during oogenesis
TL;DR: It is revealed that CHC translation begins very early during oocyte differentiation in the germarium, and a possible role for clathrin in the early fluid phase endocytotic (pinocytosis) in addition to its role in receptor-mediated endocyTosis is suggested.

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.
