The rainbow trout genome provides novel insights into evolution after whole-genome duplication in vertebrates
Vertebrate evolution has been shaped by several rounds of whole-genome duplications (WGDs) that are often suggested to be associated with adaptive radiations and evolutionary innovations. Due to an additional round of WGD, the rainbow trout genome offers a unique opportunity to investigate the early evolutionary fate of a duplicated vertebrate genome. Here we show that after 100 million years o...
متن کاملEvolution of gene function and regulatory control after whole-genome duplication: comparative analyses in vertebrates.
The significance of whole-genome duplications (WGD) for vertebrate evolution remains controversial, in part because the mechanisms by which WGD contributed to functional evolution or speciation are still incompletely characterized. Fish genomes provide an ideal context in which to examine the consequences of WGD, because the teleost lineage experienced an additional WGD soon after divergence fr...
متن کاملOrigin of the Yeast Whole-Genome Duplication
Whole-genome duplications (WGDs) are rare evolutionary events with profound consequences. They double an organism's genetic content, immediately creating a reproductive barrier between it and its ancestors and providing raw material for the divergence of gene functions between paralogs. Almost all eukaryotic genome sequences bear evidence of ancient WGDs, but the causes of these events and the ...
متن کاملMetabolic adaptation after whole genome duplication.
Whole genome duplications (WGDs) have been hypothesized to be responsible for major transitions in evolution. However, the effects of WGD and subsequent gene loss on cellular behavior and metabolism are still poorly understood. Here we develop a genome scale evolutionary model to study the dynamics of gene loss and metabolic adaptation after WGD. Using the metabolic network of Saccharomyces cer...
متن کاملA review of artificial gynogenesis in the Caspian Sea sturgeons
In sturgeon, female-sex rearing is economical and gynogenesis induction is one of the ways to achieve it. In gynogenesis, an egg develops without the genetic influence of the male, or on the other words, it is a method of reproduction in which the offspring are formed exclusively from the genetic information of the mother. In this technique, the sperm used must be genetically inactivated. Rays ...
