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:

Vitellogenesis in spiders: first analysis of protein changes in different reproductive stages of Polybetes pythagoricus
TL;DR: This study establishes, for the first time for the Order Araneae, the coexistence of three different origins of vitellogenesis-related proteins: one predominantly ovarian involving peptides of 120, 75, 46, and 30 kDa; another extraovarian one originated from the midgut diverticula and represented by a 170 k da peptide, and a third hemolymphatic one, represented by the 67 k Da peptide.

TL;DR: In this paper, an A. stephensi LRIM1 knockout line, Δaslrim1, was generated by embryonic genome editing using CRISPR-Cas9.

Effects of "Candidatus Liberibacter solanacearum" (haplotype B) on Bactericera cockerelli fitness and vitellogenesis.
Angélica Albuquerque Tomilhero Frias,Freddy Ibanez,Azucena Mendoza,William Mário de Carvalho Nunes,Cecilia Tamborindeguy +4 more
TL;DR: This study highlights the effect of Lso B infection on egg production, BcVg1‐like expression, and oocyte development, and represents the first step to understand the interaction of L so B with B. cockerelli.

Molecular Characterization of Neoseiulus barkeri Vitellogenin Genes and Vitellogenin Receptor during Reproductive Diapause
Junqi Jiang,Ying Zhang,Lei Ma,Tingting Niu,Tingting Dong,Ruirui Sheng,Ling Li,Yeyu Xu,Lingyu Xi,And Guiting Li +9 more
TL;DR: The ovarian structure in the predatory mite Neoseiulus barkeri, a species that shows promise as a biological pest control agent, was studied to explore the effects of the Vg gene and its receptor on reproduction and showed that the N. barkeri vitellogenin genes have complete domains and that the positions of many conservative regions and conservative motif are consistent.

TL;DR: The increased number of eggs laid by the fenpropathrin-resistant strain of N. barkeri may be a consequence of changes in Vg gene expression, which is significantly higher in the resistant strain than in the susceptible strain.

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.
