  1. 1. Cis-regulatory variation and divergence in Capsella

    Author : Kim A. Steige; Tanja Slotte; Jeff J. Doyle; Uppsala universitet; []
    Keywords : Capsella; Shepherd s Purse; cis-regulatory changes; allele-specific expression; mating system shift; floral evolution; polyploidy; positive selection; purifying selection; transposable elements; small RNA; methylation; transposable element silencing; distribution of fitness effects;

    Abstract : Cis-regulatory changes in e.g. promoters or enhancers that affect the expression of a linked focal gene have long been thought to be important for adaptation. In this thesis, I investigate the selective importance and genomic correlates of cis-regulatory variation and divergence in the genus Capsella, using massively parallel sequencing data. READ MORE

    Abstract : The impact of selection on regulatory variation and the contribution of regulatory changes to phenotypic variation has long been debated in evolutionary genetics. Because cis-regulatory elements such as promoters and enhancers can be difficult to identify, it has been more challenging to quantify the impact of selection on variation in cis-regulatory regions than in protein-coding regions.
