A comparative study of adaptive mutation operators for metaheuristics [PDF]

, 2009
Genetic algorithms (GAs) are a class of stochastic optimization methods inspired by the principles of natural evolution. Adaptation of strategy parameters and genetic operators has become an important and promising research area in GAs.

Radiation mutagenesis of Bacillus velezensis and its antibacterial effect on Colletotrichum gloeosporioides

Fushe yanjiu yu fushe gongyi xuebao, 2023
We used 60Co-γ ray and electron beam irradiation to mutate Bacillus velezensis to breed genetically stable mutant strains. The mutant strains were screened and re-screened by plate confrontation and the four-point method to study their antibacterial ...

Separation of cellulose from Triarrhena lutarioriparia by irradiation-assisted formic acid and characterization of its enzymatic hydrolysis

Fushe yanjiu yu fushe gongyi xuebao, 2022
In this study, Triarrhena lutarioriparia was irradiated by a 5 MeV electron accelerator. The effects of temperature, formic acid concentration, and absorbed dose on the separation efficiency of cellulose from Triarrhena lutarioriparia were investigated ...

Efficiency of carcinogenesis with and without a mutator mutation [PDF]

Proceedings of the National Academy of Sciences, 2006
Carcinogenesis involves the acquisition of multiple genetic changes altering various cellular phenotypes. These changes occur within the fixed time period of a human lifespan, and mechanisms that accelerate this process are more likely to result in clinical cancers.

Estimating the Rate of Mutation to a Mutator Phenotype

Axioms, 2023
A mutator is a variant in a population of organisms whose mutation rate is higher than the average mutation rate in the population. For genetic and population dynamics reasons, mutators are produced and survive with much greater frequency than anti-mutators (variants with a lower-than-average mutation rate).

Mutation rate plasticity in rifampicin resistance depends on Escherichia coli cell–cell interactions [PDF]

, 2014
Variation of mutation rate at a particular site in a particular genotype, in other words mutation rate plasticity (MRP), can be caused by stress or ageing. However, mutation rate control by other factors is less well characterized.

Are Protein Shape-Encoded Lowest-Frequency Motions a Key Phenotype Selected by Evolution?

Applied Sciences, 2023
At the very deepest molecular level, the mechanisms of life depend on the operation of proteins, the so-called “workhorses” of the cell. Proteins are nanoscale machines that transform energy into useful cellular work, such as ion or nutrient transport ...
