Comparative biochemistry demonstrates that the metabolites, complex biochemical networks, enzymes and regulatory mechanisms essential to all living cells are conserved in amazing detail throughout evolution. Thus, in order to evolve, an organism must overcome new adverse conditions without creating different but equally dangerous alterations in its ongoing successful metabolic relationship with its environment. Evidence suggests that stable long‐term acquisitive evolution results from minor… 

Mutation as a Stress Response and the Regulation of Evolvability

The emerging commonalities in stress-induced-mutation mechanisms provide hope for new therapeutic interventions for all of these processes, including microbial pathogenesis and antibiotic-resistance, and tumor progression and chemotherapy resistance, all of which occur under stress, driven by mutations.

Genetic instability in budding and fission yeast—sources and mechanisms

Various factors that may influence genome stability, such as cellular ploidy, the phase of the cell cycle, transcriptional activity of a particular region of DNA, the proficiency of DNA quality control systems, and finally potential exposure to endogenous or environmental stress are discussed.

Stationary Phase Mutagenesis in B. subtilis: A Paradigm to Study Genetic Diversity Programs in Cells Under Stress

Concepts pertaining to genetic programs that increase diversity in B. subtilis cells under nutritional stress that are influenced by cell differentiation and transcriptional derepression are revised and discussed.

Bacteria spend their lives buffeted by changing environmental conditions and under a variety of stressful conditions, bacteria are induced for genetic change and this transient mutator state may be important for adaptive evolution.

Hypermutation and stress adaptation in bacteria

The adaptive benefits of heritable hypermutability are discussed with emphasis on host–pathogen interactions and nonheritable (transient) hypermtability conferring significant adaptive benefits also occur during stress response although its molecular basis remains controversial.

Accumulation of phenotypically neutral genetic variance by developmental systems and phenotypic accommodation of stress-induced effects, together with the inheritance of stress—induced modifications, ensure the evolutionary persistence of stress–response strategies and provide a link between individual adaptability and evolutionary adaptation.

Perceiving molecular evolution processes in Escherichia coli by comprehensive metabolite and gene expression profiling

The vital involvement of energy metabolism and membrane-associated functional categories in all of the evolutionary conditions examined in this study are reported within the context of transcript, outer membrane protein, and metabolite levels.

Transcription-Associated Mutation in Bacillus subtilis Cells under Stress

The results demonstrate that the level of Leu(+) reversions increased significantly in parallel with the induced increase in transcription levels, and this mutagenic response was not observed under conditions of exponential growth.

Maintaining a healthy SPANC balance through regulatory and mutational adaptation

A holistic approach to bacterial adaptation, involving a gamut of regulation and mutation, is likely to be the norm in broadening the capabilities of a species, and a generalized hypothesis to explain bacterial adaptation is offered.



The influence of cellular physiology on the initiation of mutational pathways in Escherichia coli populations

Predicting all the mutations fixed in adapting populations is beyond the current understanding of evolutionary processes, but the interplay between ancestor physiology and the initiation of adaptation pathways is demonstrated and definable in bacterial populations.

Molecular mechanisms of genetic adaptation to xenobiotic compounds

Evidence is presented that a range of genetic mechanisms, such as gene transfer, mutational drift, and genetic recombination and transposition, can accelerate the evolution of catabolic pathways in bacteria, but there is virtually no information concerning the rates at which these mechanisms are operating in bacteria living in nature and the response of such rates to the presence of potential (xenobiotic) substrates.

Genome-Wide Transcriptional Profiling of theEscherichia coli Responses to Superoxide Stress and Sodium Salicylate

The genetic responses to both environmental insults revealed several common themes, including the activation of genes coding for functions that replenish reducing potential; regulate iron transport and storage; and participate in sugar and amino acid transport, detoxification, protein modification, osmotic protection, and peptidoglycan synthesis.

The generation of multiple co-existing mal-regulatory mutations through polygenic evolution in glucose-limited populations of Escherichia coli.

The multiplicity of alleles found within malT within a population derived from a single clone suggest that the periodic selection events observed previously in such populations are not a major factor in reducing genetic diversity.

Adaptive mgl-regulatory mutations and genetic diversity evolving in glucose-limited Escherichia coli populations.

Increased fitness was accompanied by the generation of genetic diversity and not the evolution of a single winner clone, as predicted by the periodic selection model of bacterial populations.

The consequences of growth of a mutator strain of Escherichia coli as measured by loss of function among multiple gene targets and loss of fitness.

Growth curves and competition tests on lineages that passed through 90 cycles of single colony isolation showed that all lineages suffered reduced fitness, and the value of mutators in cellular evolution is discussed.

Hypermutation in derepressed operons of Escherichia coli K12.

Evidence is presented that starvation for leucine in an Escherichia coli auxotroph triggers metabolic activities that specifically target the leu operon for derepression, increased rates of transcription, and mutation, and that higher rates of mutation are specifically associated with the derepressed lei operon.

Redesigning metabolic routes: manipulation of TOL plasmid pathway for catabolism of alkylbenzoates.

In the experiments described here, a catabolic pathway for alkylbenzoates specified by the TOL plasmid of Pseudomonas was restructured to produce a pathway capable of processing a new substrate, 4-ethylbenzoate, and was redesigned by recruitment of genes from mutant bacteria selected for their production of either an altered pathway operon regulator or an altered C23O that is less sensitive to metabolite inactivation.
