Three geographically separate domestications of Asian rice [PDF]
, 2015 Domesticated rice (Oryza sativa L.) accompanied the dawn of Asian civilization(1) and has become one of world's staple crops. From archaeological and genetic evidence various contradictory scenarios for the origin of different varieties of cultivated ...

Copy number variants and selective sweeps in natural populations of the house mouse (Mus musculus domesticus) [PDF]
, 2014 Copy–number variants (CNVs) may play an important role in early adaptations, potentially facilitating rapid divergence of populations. We describe an approach to study this question by investigating CNVs present in natural populations of mice in the ...

An Eco-Evolutionary approach of Adaptation and Recombination in a large population of varying size [PDF]
, 2014 We identify the genetic signature of a selective sweep in a population described by a birth-and-death process with density dependent competition. We study the limit behaviour for large K, where K scales the population size.

Frontiers in Genetics, 2020 Massive genotyping of single nucleotide polymorphisms (SNP) has opened opportunities for analyzing the way in which selection shapes genomes. Artificial or natural selection usually leaves genomic signatures associated with selective sweeps around the ...

Multiple domestications of asian rice [PDF]
, 2016 In their recent Correspondence about our study showingthat there were three origins of Asian rice2, Huang and Han suggest that the methodology that we used to infer multiple domestications was flawed as it did not take account of the strong genetic ...

Selective sweep probabilities in spatially expanding populations
, 2023 AbstractEvolution during range expansions shapes biological systems from microbial communities and tumours up to invasive species. A fundamental question is whether, when a beneficial mutation arises during a range expansion, it will evade clonal interference and sweep through the population to fixation.

The effect of recurrent mutations on genetic diversity in a large population of varying size [PDF]
, 2016 Recurrent mutations are a common phenomenon in population genetics. They may be at the origin of the fixation of a new genotype, if they give a phenotypic advantage to the carriers of the new mutation.

Genetic Variation in Human Gene Regulatory Factors Uncovers Regulatory Roles in Local Adaptation and Disease [PDF]
, 2019 Differences in gene regulation have been suggested to play essential roles in the evolution of phenotypic changes. Although DNA changes in cis-regulatory elements affect only the regulation of its corresponding gene, variations in gene regulatory factors

Does Corticothalamic Feedback Control Cortical Velocity Tuning? [PDF]
, 2001 The thalamus is the major gate to the cortex and its contribution to cortical receptive field properties is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic ...

Natural variation in abiotic stress responsive gene expression and local adaptation to climate in Arabidopsis thaliana. [PDF]
, 2014 Gene expression varies widely in natural populations, yet the proximate and ultimate causes of this variation are poorly known. Understanding how variation in gene expression affects abiotic stress tolerance, fitness, and adaptation is central to the ...
