| the link between independent acquisition of intracellular gamma-endosymbionts and concerted evolution in tremblaya princeps. | many insect species establish mutualistic symbiosis with intracellular bacteria that complement their unbalanced diets. the betaproteobacterium "candidatus tremblaya" maintains an ancient symbiosis with mealybugs (hemiptera: pseudococcidae), which are classified in subfamilies phenacoccinae and pseudococcinae. most phenacoccinae mealybugs have "candidatus tremblaya phenacola" as their unique endosymbiont, while most pseudococcinae mealybugs show a nested symbiosis (a bacterial symbiont placed in ... | 2015 | 26161080 |
| molecular evidence for ongoing complementarity and horizontal gene transfer in endosymbiotic systems of mealybugs. | intracellular bacterial supply of essential amino acids is common among sap-feeding insects, thus complementing the scarcity of nitrogenous compounds in plant phloem. this is also the role of the two mealybug endosymbiotic systems whose genomes have been sequenced. in the nested endosymbiotic system from planococcus citri (pseudococcinae), "candidatus tremblaya princeps" and "candidatus moranella endobia" cooperate to synthesize essential amino acids, while in phenacoccus avenae (phenacoccinae) ... | 2014 | 25206351 |
