Wolbachia infection in the small brown planthopper Laodelphax striatellus elevates ovarian 20-hydroxyecdysone (20E) and increases fecundity by stimulating tropharium germline and precursor cell proliferation.
- Why it matters: Wolbachia boosts egg production in this host, but how it uses host endocrine signaling to drive reproduction was unclear.
- What they did: The study measured ovarian ecdysone and 20E, used RNA interference to knock down CYP315A1 and CYP314A1, supplemented 20E, mapped germline stem cells and mitotic nurse cell precursors in the tropharium, and microinjected Wolbachia into uninfected females.
- The result: Infection increased ovarian ecdysone and 20E; CYP315A1/CYP314A1 knockdown reduced hormone titres and fecundity, while 20E supplementation restored egg production, and Wolbachia microinjection raised 20E, increased tropharium proliferation, lowered apoptosis, and increased fecundity.
