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 ...

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).

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.

An Evolutionary Reduction Principle for Mutation Rates at Multiple Loci [PDF]

, 2010
A model of mutation rate evolution for multiple loci under arbitrary selection is analyzed. Results are obtained using techniques from Karlin (1982) that overcome the weak selection constraints needed for tractability in prior studies of multilocus event
