Recent and Ancient Signature of Balancing Selection around the S-Locus in Arabidopsis halleri and A. lyrata [PDF]

open access: yes, 2012
Balancing selection can maintain different alleles over long evolutionary times. Beyond this direct effect on the molecular targets of selection, balancing selection is also expected to increase neutral polymorphism in linked genome regions, in inverse ...

Structural and mechanistic basis for the regulation of the chloroplast signal recognition particle by (p)ppGpp

open access: yesFEBS Letters, EarlyView.
LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Functional analysis of a gene locus in response to non-canonical combinations of transcription factors [PDF]

open access: yesarXiv, 2023
Transcription factor combinations determine gene locus activity and thereby cell identity. However, the precise link between concentrations of such activating transcription factors and target-gene activity is ambiguous. Here we investigate this link for the gap gene dependent activation of the even-skipped (eve) locus in the Drosophila embryo.

Mating-system evolution in Euplotes, from the Mendelian to a molecular approach. [PDF]

open access: yes, 2013
Euplotes evolved multiple mating systems which have for long been assumed to be determined by "open" series of alleles at a single mat locus. Families of mating type-specific pheromones and of their mat coding genes have been extensively characterized ...

The multiple roles of the NlpC_P60 peptidase family in mycobacteria – an underexplored target for antimicrobial drug discovery

open access: yesFEBS Letters, EarlyView.
The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Dominance and multi-locus interaction [PDF]

open access: yesarXiv, 2023
Dominance is usually considered a constant value that describes the relative difference in fitness or phenotype between heterozygotes and the average of homozygotes at a focal polymorphic locus. However, the observed dominance can vary with the genetic background of the focal locus.

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

The genetic basis of resistance and matching-allele interactions of a host-parasite system: The Daphnia magna-Pasteuria ramosa model. [PDF]

open access: yesPLoS Genetics, 2017
Negative frequency-dependent selection (NFDS) is an evolutionary mechanism suggested to govern host-parasite coevolution and the maintenance of genetic diversity at host resistance loci, such as the vertebrate MHC and R-genes in plants.

Tackling the dimensions in imaging genetics with CLUB-PLS [PDF]

open access: yesarXiv, 2023
A major challenge in imaging genetics and similar fields is to link high-dimensional data in one domain, e.g., genetic data, to high dimensional data in a second domain, e.g., brain imaging data. The standard approach in the area are mass univariate analyses across genetic factors and imaging phenotypes.

Using Microsatellites to Assess Genetic Variation in a Selective Breeding Program of Chinese Bay Scallop (Argopecten irradians irradians) [PDF]

open access: yes, 2013
This study aimed to improve our understanding of the genetics of the Chinese bay scallop (Argopecten irradians irradians), one of the most important maricultured shellfish in China.
