Evolution under fluctuating environments explains observed robustness in metabolic networks. [PDF]

open access: yesPLoS Computational Biology, 2010
A high level of robustness against gene deletion is observed in many organisms. However, it is still not clear which biochemical features underline this robustness and how these are acquired during evolution.

Punctuated evolution and robustness in morphogenesis [PDF]

open access: yesBiosystems, 2014
This paper presents an analytic approach to the pattern stability and evolution problem in morphogenesis. The approach used here is based on the ideas from the gene and neural network theory. We assume that gene networks contain a number of small groups of genes (called hubs) controlling morphogenesis process.

Does mutational robustness inhibit extinction by lethal mutagenesis in viral populations? [PDF]

open access: yesPLoS Computational Biology, 2010
Lethal mutagenesis is a promising new antiviral therapy that kills a virus by raising its mutation rate. One potential shortcoming of lethal mutagenesis is that viruses may resist the treatment by evolving genomes with increased robustness to mutations ...

Revisiting robustness and evolvability: evolution in weighted genotype spaces. [PDF]

open access: yesPLoS ONE, 2014
Robustness and evolvability are highly intertwined properties of biological systems. The relationship between these properties determines how biological systems are able to withstand mutations and show variation in response to them. Computational studies

Genes confer similar robustness to environmental, stochastic, and genetic perturbations in yeast. [PDF]

open access: yesPLoS ONE, 2010
Gene inactivation often has little or no apparent consequence for the phenotype of an organism. This property-enetic (or mutational) robustness-is pervasive, and has important implications for disease and evolution, but is not well understood.

Developmental Evolution: Getting Robust About Robustness [PDF]

open access: yesCurrent Biology, 2002
In the context of development, a process is robust if it can proceed normally despite the enormous capacity for perturbation inherent in all biological systems. A new mode of theoretical modeling of genetic networks holds great promise for increasing our understanding of both the quantitative mechanisms of robustness and its evolutionary impact.

Recombination drives the evolution of mutational robustness [PDF]

open access: yesCurrent Opinion in Systems Biology, 2019
Recombination can impose fitness costs as beneficial parental combinations of alleles are broken apart, a phenomenon known as recombination load. Computational models suggest that populations may evolve a reduced recombination load by reducing either the likelihood of recombination events (bring interacting loci in physical proximity) or the strength ...

Recombination and the evolution of mutational robustness

open access: yesJournal of Theoretical Biology, 2006
Mutational robustness is the degree to which a phenotype, such as fitness, is resistant to mutational perturbations. Since most of these perturbations will tend to reduce fitness, robustness provides an immediate benefit for the mutated individual. However, robust systems decay due to the accumulation of deleterious mutations that would otherwise have ...
