Individual and combined benefits of different nonequilibrium proofreading mechanisms

Paolo De Los Rios, Daniel Maria Busiello, Stefano Zamuner, Adélaïde Alice Mohr

Genome duplication, transcription, and translation are among many crucial cellular processes that need to be performed with high fidelity. However, those extremely low error rates cannot be explained with simple equilibrium thermodynamic considerations. Th ...

Homoeolog Inference Methods Requiring Bidirectional Best Hits or Synteny Miss Many Pairs

Shaoline Sheppard

Homoeologs are pairs of genes or chromosomes in the same species that originated by speciation and were brought back together in the same genome by allopolyploidization. Bioinformatic methods for accurate homoeology inference are crucial for studying the e ...

Single-cell studies of Mycobacterium smegmatis cell cycle using time-lapse fluorescence microscopy

Joëlle Xiao Yuan Ven

Cell division is one of the most primordial cellular processes and is essential for life propagation. It is composed of crucial events, namely genome duplication, chromosomes segregation and membrane separation. Failure of these processes will have dramati ...

Diet modulates cecum bacterial diversity and physiological phenotypes across the BXD mouse genetic reference population

Johan Auwerx, Evan Graehl Williams

The BXD family has become one of the preeminent genetic reference populations to understand the genetic and environmental control of phenotypic variation. Here we evaluate the responses to different levels of fat in the diet using both chow diet (CD, 13-18 ...

Detecting and Quantifying Changing Selection Intensities from Time-Sampled Polymorphism Data

Jeffrey David Jensen, Matthieu Foll, Sebastian Matuszewski, Hyunjin Shim, Stefan Jean Laurent

During his well-known debate with Fisher regarding the phenotypic dataset of Panaxia dominula, Wright suggested fluctuating selection as a potential explanation for the observed change in allele frequencies. This model has since been invoked in a number of ...

Topological Domains, Metagenes, and the Emergence of Pleiotropic Regulations at Hox Loci

Denis Duboule, Fabrice Daniel Darbellay

Hox gene clusters of jaw vertebrates display a tight genomic organization, which has no equivalent in any other bilateria genomes sequenced thus far. It was previously argued that such a topological consolidation toward a condensed, metagenic structure was ...

Comparing genomes with rearrangements and segmental duplications

Bernard Moret, Mingfu Shao

Motivation: Large-scale evolutionary events such as genomic rearrange. ments and segmental duplications form an important part of the evolution of genomes and are widely studied from both biological and computational perspectives. A basic computational pro ...

Effects of ploidy and sex-locus genotype on gene expression patterns in the fire ant Solenopsis invicta

Chitsanu Khurewathanakul, Oksana Riba Grognuz, Laurent Keller

Males in many animal species differ greatly from females in morphology, physiology and behaviour. Ants, bees and wasps have a haplodiploid mechanism of sex determination whereby unfertilized eggs become males while fertilized eggs become females. However, ...

Genomic context analysis reveals dense interaction network between vertebrate ultraconserved non-coding elements

Philipp Bucher, Slavica Dimitrieva Janeva

Motivation: Genomic context analysis, also known as phylogenetic profiling, is widely used to infer functional interactions between proteins but rarely applied to non-coding cis-regulatory DNA elements. We were wondering whether this approach could provide ...

Polyploidy and invasion success: trait trade-offs in native and introduced cytotypes of two Asteraceae species

Alexandre Buttler, François Gillet, Aurélie Thébault

Invasion success is favoured by the introduction of pre-adapted genotypes. In addition, novel pressures in the introduced range may lead to phenotypic changes related to fitness or competitive ability of introduced plants. Polyploidy appears to be over-rep ...
