Adapting the engine to the fuel: mutator populations can reduce the mutational load by reorganizing their genome structure

BMC Evolutionary Biology, 2019
Background Mutators are common in bacterial populations, both in natural isolates and in the lab. The fate of these lineages, which mutation rate is increased up to 100 ×, has long been studied using population genetics models, showing that they can ...

Lamin B1 safeguards the B cell genome and shapes lymphoma outcome

HemaSphere, Volume 10, Issue 6, June 2026.
Abstract Lamin B1 is a structural component of the nuclear lamina that participates in genome organization and transcriptional control. During adaptive immune responses, B lymphocytes in germinal centers (GCs) undergo clonal expansion and programmed DNA damage at immunoglobulin loci, while simultaneously downregulating Lamin B1.

The cyclin‐dependent kinase inhibitor KIP‐RELATED PROTEIN 6 promotes stem cell death upon DNA damage in Arabidopsis roots

The Plant Journal, Volume 126, Issue 5, June 2026.
SUMMARY Maintenance of genome integrity is essential for plant growth and survival. Plants have evolved specialised DNA damage responses that coordinate DNA repair, cell cycle arrest and stem cell‐specific cell death. However, the mechanism through which damaged stem cells are selectively eliminated remains unclear.

PINK1 regulated mitophagy is evident in skeletal muscles

Autophagy Reports
PINK1, mutated in familial forms of Parkinson’s disease, initiates mitophagy following mitochondrial depolarization. However, it is difficult to monitor this pathway physiologically in mice as loss of PINK1 does not alter basal mitophagy levels in most ...

Genomic clustering of fitness‐affecting mutations favors the evolution of chromosomal instability

Evolutionary Applications, 2019
Most solid cancers are characterized by chromosomal instability (CIN)—an elevated rate of large‐scale chromosomal aberrations and ploidy changes. Chromosomal instability may arise through mutations in a range of genomic integrity loci and is commonly ...

Rare Natural SNP Activates SHOOT APICAL MERISTEM ENLARGER1 to Increase Branch Number and Silique Number on the Main Inflorescence in Brassica napus

Plant Biotechnology Journal, Volume 24, Issue 5, Page 2768-2786, May 2026.
ABSTRACT Brassica napus is the second most important oil crop worldwide. Number of primary branches (Branch number, BN) and silique number on the main inflorescence (SMI) are key yield‐related quantitative traits. Here, we cloned a major QTL, qDB.A09, which simultaneously influences BN and SMI.

Mutating OWLs: Semantic Mutation Testing for Ontologies [PDF]

Proceedings of the International Workshop on domAin specific Model-based AppRoaches to vErificaTion and validaTiOn, 2016
Ontologies are an essential component of semantic knowledge bases and applications, and nowadays they are used in a plethora of domains. Despite the maturity of ontology languages, support tools and engineering techniques, the testing and validation of ontologies is a field which still lacks consolidated approaches and tools.

Strictly Dominated Strategies in the Replicator-Mutator Dynamics

Games, 2011
The replicator-mutator dynamics is a set of differential equations frequently used in biological and socioeconomic contexts to model evolutionary processes subject to mutation, error or experimentation.

Inference of Candidate Germline Mutator Loci in Humans from Genome-Wide Haplotype Data. [PDF]

PLoS Genetics, 2017
The rate of germline mutation varies widely between species but little is known about the extent of variation in the germline mutation rate between individuals of the same species.

A Super‐Pangenome for Cultivated Citrus Reveals Evolutive Features During the Allopatric Phase of Their Reticulate Evolution

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3345-3367, May 2026.
Structure of the cultivated citrus super‐pangenome. ABSTRACT The main genetic diversity observed in cultivated citrus results from a reticulate evolution involving four ancestral taxa whose radiation occurred in allopatry. In such context, GWAS analysis, genome diversity and transcriptomic studies will be significantly enhanced through pangenome ...
