gcodeml: A Grid-enabled Tool for Detecting Positive Selection in Biological Evolution [PDF]
, 2012 One of the important questions in biological evolution is to know if certain changes along protein coding genes have contributed to the adaptation of species. This problem is known to be biologically complex and computationally very expensive.

The draft genome of the blood pheasant (Ithaginis cruentus): Phylogeny and high‐altitude adaptation
Ecology and Evolution, 2020 The blood pheasant (Ithaginis cruentus), the only species in the genus Ithaginis, lives in an extremely inhospitable high‐altitude environment, coping with hypoxia and ultraviolet (UV) radiation.

Genomic basis of ecological niche divergence among cryptic sister species of non-biting midges [PDF]
, 2013 Background: There is a lack of understanding the evolutionary forces driving niche segregation of closely related organisms. In addition, pinpointing the genes driving ecological divergence is a key goal in molecular ecology.

Hitchhiking Under Positive Darwinian Selection [PDF]
Genetics, 2000 Abstract Positive selection can be inferred from its effect on linked neutral variation. In the restrictive case when there is no recombination, all linked variation is removed. If recombination is present but rare, both deterministic and stochastic models of positive selection show that linked variation hitchhikes to either low or high ...

Frontiers in Ecology and Evolution, 2015 In moths, mate finding strongly rely on the detection of sex pheromones by pheromone receptors. Any modification in the functional properties of these receptors can have a drastic impact on reproduction.

T cell self-reactivity during thymic development dictates the timing of positive selection
eLife, 2021 Functional tuning of T cells based on their degree of self-reactivity is established during positive selection in the thymus, although how positive selection differs for thymocytes with relatively low versus high self-reactivity is unclear.

Evolution and Structural Analyses of Glossina morsitans (Diptera; Glossinidae) Tetraspanins
Insects, 2014 Tetraspanins are important conserved integral membrane proteins expressed in many organisms. Although there is limited knowledge about the full repertoire, evolution and structural characteristics of individual members in various organisms, data obtained

Prediction of Genes Related to Positive Selection Using Whole-Genome Resequencing in Three Commercial Pig Breeds [PDF]
Genomics & Informatics, 2015 Selective sweep can cause genetic differentiation across populations, which allows for the identification of possible causative regions/genes underlying important traits.

Viral Interference with Functions of the Cellular Receptor Tyrosine Phosphatase CD45
Viruses, 2015 The receptor tyrosine phosphatase CD45 is expressed on the surface of almost all cells of hematopoietic origin. CD45 functions are central to the development of T cells and determine the threshold at which T and B lymphocytes can become activated.
