In silico knock-out experiments with iBSCc showed that the consortium metabolism is a highly integrated yet fragile network. ...
Here we present a genome-scale metabolic network (GEM) for the bacterial consortium from the cedar aphid iBSCc. ...
Altogether, the two metabolic networks involved in the C. cedri consortium are highly constrained and fragile. ...

If we take gene essentiality as a proxy of network fragility, small metabolic networks are more fragile against gene FIGURE 1 | Network fragility increases with metabolic minimization. ...
In other words, the number of alternative pathways able to rescue for a specific deleted enzymatic step is drastically reduced and the consequent fragility of the network could limit its usefulness as ...

We found that the evolution of free-living to host-restricted lifestyle rendered a fragile metabolic network where >80% of genes in the chromatophore are essential for metabolic functionality. ...
In addition, our in silico simulations of the evolutionary process leading to the reduced metabolic network of the chromatophore showed that the predicted rate of released reduced-carbon is obtained in ...

Aphids engage in a nutritional symbiosis with a so-called primary symbiont, Buchnera aphidicola, but also harbor a secondary bacterial symbiont, Hamiltonella defensa, which confers protection against parasitoid ...
