    Alternate mutation modalities in models of population dynamics by Jonathan Bartlett

    Published 2024-12-01
    “… Most comprehensive simulations of population dynamics use origin-fixation approaches to modeling mutations, specifically modeling mutation using the framework of the modern synthesis. …”

    Predicting the evolution of bacterial populations with an epistatic selection-mutation model by Raul Donangelo, Hugo Fort

    Published 2024-06-01
    “…It incorporates two recently noticed phenomena related to mutations: (i) the fact that the marginal improvement from a beneficial mutation declines with increasing fitness or diminishing returns epistasis and (ii) for some hypermutator variants, the mutation rate for the bacterial DNA undergoes a sudden increase by at least one order of magnitude. …”

    The landscape of nucleotide diversity in Drosophila melanogaster is shaped by mutation rate variation by Barroso, Gustavo V, Dutheil, Julien Y

    Published 2023-04-01
    “…Here we present a new statistical method that jointly infers the genomic landscapes of genealogies, recombination rates and mutation rates. In doing so, our model captures the effects of genetic drift, linked selection and local mutation rates on patterns of genomic variation. …”

    Combined Parental Thrombophilia Gene Mutation Defects in Couples with Repeated Pregnancy Loss by Mehdi Kashifard, Zahra Basirat, Fatemeh Ramezani, Faeze Ghofrani, Masoumeh Golsorkhtabaramiri

    Published 2023-10-01
    “…Background: Several genetic mutations in female thrombotic defects have recently been shown to affect recurrent pregnancy loss (RPL); however, it is unclear which common parental mutations are involved in thrombosis-associated repeated pregnancy loss RPL. …”

    Exploring the potential role of EPSPS mutations for enhanced glyphosate resistance in Nicotiana tabacum by Bingjie Li, Bingjie Li, Chen Chen, Chen Chen, Mengmeng Cui, Yuhe Sun, Jing Lv, Changbo Dai

    Published 2025-02-01
    “…In this study, we engineered two mutant variants of the tobacco EPSPS gene through amino acid substitution (TIPS-NtEPSPS and P180S-NtEPSPS). These mutated EPSPS genes were overexpressed in tobacco under the control of CaMV35S promoters. …”

    D-stem mutation in an essential tRNA increases translation speed at the cost of fidelity. by Madison N Schrock, Krishna Parsawar, Kelly T Hughes, Fabienne F V Chevance

    Published 2025-02-01
    “…This work, taken in context with the Hirsh UGA nonsense suppressor G24A mutation in TrpT tRNA, provides genetic evidence that the post-GTP hydrolysis proofreading step by elongation factor Tu may be controlled by structural interactions in the hinge region of tRNA species. …”

    The fate of recessive deleterious or overdominant mutations near mating-type loci under partial selfing by Tezenas, Emilie, Giraud, Tatiana, Véber, Amandine, Billiard, Sylvain

    Published 2023-01-01
    “…In particular, under what conditions deleterious mutations are likely to be maintained for long enough near mating-compatibility genes remains to be evaluated, especially under selfing, which generally increases the purging rate of deleterious mutations. …”
