Abstract:Sap-feeding insects often maintain multiple nutritional endosymbionts, which act in concert to produce compounds essential for insect survival. Many mealybugs have endosymbionts in a nested configuration: one or two bacterial species reside within the cytoplasm of another bacterium, and to-gether these bacteria have genomes which encode interdependent but complete sets of genes needed to produce key nutritional molecules. Here we show that the mealybugPseudococcus viburnihas three endosymbionts, one of which c… Show more
