A horizontally acquired pantothenate gene drives vitellogenin's benefit to whitefly symbiosis persistence

Insect Science, EarlyView.
This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

Vitellogenin as a multigene family. Not all Xenopus vitellogenin genes may be in an “expressible” configuration.

Journal of Biological Chemistry, 1980
DNA-cDNA titrations suggest that the Xenopus genome comprises two albumin genes, whereas there are 12 to 16 vitellogenin-like genes. Both sets of genes are expressed in liver, those coding for albumin constitutively, but vitellogenin only when induced by estrogen in both male and female frogs.

FOXL2 down-regulates vitellogenin expression at mature stage in Eriocheir sinensis

Bioscience Reports, 2015
The present study highlights that forkhead transcription factor (FOXL)2 down-regulates vitellogenin (VTG) synthesis not only through the regulation of follicular cell apoptosis with DEAD-box RNA helicase 20 (DDX20), but also may through the steroidogenic

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

Integrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Supplementation of Pangasianodon hypophthalmus broodstock feed with katuk extract, turmeric powder, and vitamin C before mating resulted in higher fecundity and produced larvae and juveniles with better growth performance

Journal of the World Aquaculture Society
Increased vitellogenin availability for deposition in oocytes can improve the success of embryonal growth and development and the quality of catfish larvae and juveniles produced. This study aimed to evaluate the effects of katuk extract, turmeric powder,

Transovarial Transmission of a Plant Virus Is Mediated by Vitellogenin of Its Insect Vector

PLoS Pathogens, 2014
Most plant viruses are transmitted by hemipteroid insects. Some viruses can be transmitted from female parent to offspring usually through eggs, but the mechanism of this transovarial transmission remains unclear.

A lipid‐sensitive food choice behavior influences aging outcomes from a longevity‐promoting diet

The FEBS Journal, EarlyView.
C. elegans are exposed to a variety of bacteria in their natural environment and must be able to distinguish between beneficial and detrimental food sources. We show that C. elegans exposed to the bacterium from their natural habitat, Methylobacterium, disrupts lipid homeostasis, causing worms to avoid this bacterial species and choose the laboratory ...

Syntaxin-1A Silencing by RNAi Disrupts Growth and Reproduction in the Asian Citrus Psyllid, Diaphorina citri

Insects
Diaphorina citri is the primary global vector of “Candidatus Liberibacter asiaticus”, the bacterium responsible for Huanglongbing. Syntaxin-1A (Syx1A), a member of the Qa-SNARE family, is essential for vesicle fusion and signal transduction, though its ...

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Exploring the role of juvenile hormone and vitellogenin in reproduction and social behavior in bumble bees

BMC Evolutionary Biology, 2014
BackgroundThe genetic and physiological pathways regulating behavior in solitary species are hypothesized to have been co-opted to regulate social behavior in social species.
