Differential expression of DTSsa4 Tc1-like transposons in closely related populations of Baikal ciscoes

Two representatives of Baikal ciscoes—lake cisco and omul—diverged from a common ancestor as recently as 10–20 thousand years ago. We have found an increasing expression level of DTSsa4 Tc1-like DNA transposons in cisco and omul brains. The mapping of the sequences of these transposons from Salmo sa...

Description
Summary:Two representatives of Baikal ciscoes—lake cisco and omul—diverged from a common ancestor as recently as 10–20 thousand years ago. We have found an increasing expression level of DTSsa4 Tc1-like DNA transposons in cisco and omul brains. The mapping of the sequences of these transposons from Salmo salar and Danio rerio genomes has shown that in some cases, these transposons are located in the 5′ and 3′ regions, as well as in the promoter regions of various genes. Probably, Tc1-like transposons affect the activity of neighboring genes, providing the adaptive divergence of the cisco population.
