Background: Goat populations that are characterized within the AdaptMap project cover a large part of the worldwide distribution of this species and provide the opportunity to assess their diversity at a global scale. We analysed genome-wide 50K single nuc ...

BMC2018

Several lineages of symbiotic bacteria in insects selfishly manipulate host reproduction to spread in a population 1 , often by distorting host sex ratios. Spiroplasma poulsonii2,3 is a helical and motile, Gram-positive symbiotic bacterium that resides in ...

Common and unique strategies of male killing evolved in two distinct Drosophila symbionts

Bruno Lemaitre, Toshiyuki Harumoto

Male killing is a selfish reproductive manipulation caused by symbiotic bacteria, where male offspring of infected hosts are selectively killed. The underlying mechanisms and the process of their evolution are of great interest not only in terms of fundame ...

Understanding both the role of selection in driving phenotypic change and its underlying genetic basis remain major challenges in evolutionary biology. Here, we use modern tools to revisit a classic system of local adaptation in the North American deer mou ...

Fusing Individual-based Models with Genome-scale Metabolic Networks - a Novel Approach for Quantifying Emergent Microbial Community Spatiotemporal Dynamics

Vassily Hatzimanikatis, Meriç Ataman, Dani Or

Metabolic capabilities of organisms govern their growth characteristics and their capability to adapt to changing environmental conditions. In natural systems, substrates can change dynamically and spatially with multiple species competing for resources. G ...

Cellular heterogeneity is ubiquitous in any cell population. Understanding these variations is key to answering fundamental questions in immunology, developmental biology, cancer or stem cell biology. For instance, single-cell in vitro and in vivo assays h ...

The Drosophila gut response to infection

Maroun Bou Sleiman

Genetic, physiological, and biochemical studies have successfully ascribed functions to genes in diverse processes. However, the majority of our knowledge in biology is qualitative in nature and is usually based on classical screens, where large effects on ...

The Genomic Signature of Population Reconnection Following Isolation: From Theory to HIV

Amalio Telenti, Jeffrey David Jensen, Séverine Vuilleumier Varisco

Ease of worldwide travel provides increased opportunities for organisms not only to colonize new environments but also to encounter related but diverged populations. Such events of reconnection and secondary contact of previously isolated populations are w ...

Remarkably Divergent Regions Punctuate the Genome Assembly of the Caenorhabditis elegans Hawaiian Strain CB4856

Tobias Johannes Schmid, Roel Paulus Josephus Bevers

The Hawaiian strain (CB4856) of Caenorhabditis elegans is one of the most divergent from the canonical laboratory strain N2 and has been widely used in developmental, population, and evolutionary studies. To enhance the utility of the strain, we have gener ...

A Systematic Survey of an Intragenic Epistatic Landscape

Jeffrey David Jensen, Claudia Bank

Mutations are the source of evolutionary variation. The interactions of multiple mutations can have important effects on fitness and evolutionary trajectories. We have recently described the distribution of fitness effects of all single mutations for a nin ...
