Wolbachia enhances ovarian development in the rice planthopper Laodelphax striatellus through elevated energy production
2025
Overview
The endosymbiont
Wolbachia
can both benefit host nutrition and manipulate host reproduction to its own advantage. However, the mechanisms of its nutritional benefits remain unclear. We show that
Wolbachia
enhances ovarian development in the small brown planthopper
Laodelphax striatellus
by boosting energy production.
Wolbachia
-infected females have increased fecundity, accelerated ovarian development, and prolonged oviposition. Enhanced activity of mitochondrial complex I is linked to increased ATP production and the expression of energy metabolism-related genes. We further identify that
Wolbachia
-synthesized riboflavin is crucial for ATP production and ovarian development. A riboflavin transporter,
slc52a3a
, positively correlates with
Wolbachia
density and is required for normal ovarian maturation. Our findings demonstrate that
Wolbachia
-produced riboflavin drives energy production and accelerates ovarian maturation, thus improving host fecundity. This research reveals insights into symbiont-host metabolic interactions and underscores the role of nutrient delivery in symbiosis.
Wolbachia
affects host reproduction and nutrition, but the underlying mechanisms are unclear. This study suggests
Wolbachia
enhances ovarian development in
Laodelphax striatellus
via riboflavin synthesis, driving ATP production and ovarian maturation.
