Mutation bias reflects natural selection in Arabidopsis thaliana

Nature, 2022
Since the first half of the twentieth century, evolutionary theory has been dominated by the idea that mutations occur randomly with respect to their consequences1.

Effects of γ-ray irradiation and particle size on enzymatic hydrolysis and fermentation of reed straws

Fushe yanjiu yu fushe gongyi xuebao, 2023
To explore the effects of absorbed dose and particle size on enzymatic hydrolysis and fermentation of reed straws (Phragmites australias), the straws were irradiated with γ-ray irradiation at different doses (0-500 kGy) and then passed through different ...

The genetic equidistance result of molecular evolution is independent of mutation rates [PDF]

, 2008
The well-established genetic equidistance result shows that sister species are approximately equidistant to a simpler outgroup as measured by DNA or protein dissimilarity.

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 ...

VarScan 2: somatic mutation and copy number alteration discovery in cancer by exome sequencing.

Genome Research, 2012
Cancer is a disease driven by genetic variation and mutation. Exome sequencing can be utilized for discovering these variants and mutations across hundreds of tumors. Here we present an analysis tool, VarScan 2, for the detection of somatic mutations and

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
