Different sorts of variants exist in genomes, among them we can distinguish nucleotides variants such as SNPs, or more large scale variants, such as structural variants, genome duplication, etc. Such large scale variants are less studied, mainly because they are more difficult to detect and analyze.
My project aims to understand how these variants can impact genome evolution in Atlantic salmon (Salmo salar). Atlantic salmon is known to have a very dynamic genome, which makes it very interesting to study large scale variants. I am thus studying how these variants, particularly structural variants and transposable elements, impact genome evolution in different populations of salmon, and in closely related species.

Moreover, Atlantic salmon has undergone a relatively recent Whole Genome Duplication (WGD) event ~80 ma ago. I am thus also studying how this event impacts the evolution of this species.
These variants can also drastically modify gene expression. This can lead to important changes in phenotype that can potentially be adaptive. Thus, another aim of my project is to investigate how these large scale variants contribute to variation in gene expression and identify affected genes under selection. These results could contribute to the sustainable maintenance of both wild and farmed Atlantic salmon.
