Mechanisms of Emerging RNA Virus Adaptation to Hosts
… virus (MAYV) and SARS-CoV-2. We used either selective sweep detection methods or experimental evolution to identify viral mutations with putative adaptive potential. A selective sweep region was identified in the Spike gene of human SARS-CoV-2 sequences. A residue at site 519 in this region …

Dissecting the evolutionary forces shaping sex chromosome evolution in papaya
… experiencing strong positive selection due to a selective sweep during human domestication. This is the first case where human domestication resulted in the evolution of a new Y chromosome with novel functions which subject it to unique evolutionary constraints. The whole genome resequencing data …

Genetische Untersuchungen zum Interleukin-13 Rezeptor alpha2 – einem Kandidatengen der Atopieentstehung
… auf evolutionäre Koaleszenz-Ereignisse wie „selective sweep“ und „bottlenecks“ (Populations-Engstellen) zurückzuführen ist. Auch spekulative Annahmen wie die eines geschützten chromosomalen Bereichs unterstützen diese These. <br> <br>Zusammenfassend lässt sich sagen, dass die vorliegenden …

Genetic Diversity And Evolution Of Disease Response Genes In Sorghum Bicolor L. Moench And Other Cereals
… of polymorphism found are consistent with both selective sweeps and balancing selection. The sorghum mlo homolog and SESPY, have old, divergent alleles, while a peroxidase and a gene with a RNA binding domain have significantly reduced diversity suggesting a recent selective sweep. Finally, we …

The Maintenance of Genetic Variation by Environmental Selection
… by mutation, eliminated by genetic drift or selective sweep, and maintained by balancing selection that favors different alleles in different environments or time. In my dissertation, I will address how spatially heterogeneous environmental selection maintains genetic variation in two …

Phylogeography of the Asia Ii and the Americas Major Clades of the Bemisia Tabaci Sibling Species Group
… demographic expansion following a recent selective sweep or bottleneck. This event explains the predominance of Asia II-1 in Pakistan and its spread towards the southern province of Sindh. Additionally, differences in DNA polymorphism and diversity between mtCOI fragments derived in …

POPULATION GENETIC APPROACHES FOR THE STUDY OF COMPLEX TRAITS: FOCUS ON INFECTIOUS AND AUTOIMMUNE DISEASES
… and have therefore acted as a powerful selective force. Therefore, several human genes have evolved in response to infectious agents. Indeed, it has been suggested that human populations may have adapted to pathogens to such a degree that the lower exposure to infectious agents in modern …

Dichlorodiphenyltricholorethane (DDT) resistance mechanisms in Drosophila melanogaster and applications for the cowpea pest Clavigralla tomentosicollis
… 91-C. Chapter 2 provides a whole-genome selective sweep analysis to identify loci with additive genetic effects in the highly DDT resistant 91-R. This study revealed only two previously identified genes related to DDT-resistance (NinaC and Cyp4g1), suggesting a new set of candidate genes …

Identifying mechanisms of pyrethroid resistance in the navel orangeworm and novel methods of control
… based upon previous research that identified a selective sweep in the A. transitella genome delimited by a point mutation kdr in the para gene that alters the conformation of the voltage-gated sodium channel and confers resistance to pyrethroids. This mutation was identified in three separate …
