Parasitoid wasps, one of the most diverse and species-rich animal groups on Earth, produce venoms that manipulate host development physiology to exploit resources. However, mechanisms actions these remain poorly understood. Here, we discovered endoparasitoid wasp, Asobara japonica , induces apoptosis, autophagy, mitotic arrest in adult tissue precursors its Drosophila larvae. We termed this phenomenon imaginal disc degradation (IDD). A multi-omics approach facilitated identification two...
Evolutionary dynamics of diversification brain neuronal cell types that have underlain behavioral evolution remain largely unknown. Here, we compared transcriptomes and functions Kenyon (KC) compose the mushroom bodies between honey bee sawfly, a primitive hymenopteran insect whose KCs likely ancestral properties. Transcriptome analyses show sawfly KC type shares some gene expression profile with each type, although unique profiles also been acquired in type. In addition, functional analysis...
Asobara japonica is an endoparasitic wasp that parasitizes Drosophila flies. It synthesizes various toxic components in the venom gland and injects them into host larvae during oviposition. To identify characterize these for enabling parasitism, we performed whole-genome sequencing (WGS) devised a protocol RNA interference (RNAi) with A. japonica. Because it has parthenogenetic lineage due to Wolbachia infection, generated clonal strain from single obtain highly homogenous genomic DNA. The...
Abstract Parasitoid wasps, one of the most diverse and species-rich animal taxa on Earth, produce venoms that manipulate host development physiology to exploit resources. However, mechanisms venom action remain poorly understood. Here, we show infection Drosophila by endoparasitoid wasp, Asobara japonica , triggers imaginal disc degradation (IDD) inducing apoptosis, autophagy, mitotic arrest, leading impaired metamorphosis. A multi-omics approach identified two proteins A. necessary for IDD....
