I’m a PhD-student in the research group of Plant Ecology and Systematics since March 2010. I have a general interest in evolutionary questions and conservation biology. I’m working with ecotype differentiation within the hemi-parasitic plant Rhinanthus serotinus. An ecotype is a variant of a species that is genetically adapted to certain environmental conditions, but which is interfertile with other ecotypes of the same species. It is thought that morphologically similar ecotypes can arise repeatedly, given that populations are subjected to similar selective regimes. But, even if parallel evolution of ecotypes is commonly discussed in literature, few attempts have been made to test the hypothesis using molecular tools.
The focus of my PhD-project is to test the hypothesis of recurrent origin of the specialized ecotypes of R. serotinus using a combination of molecular markers and extensive common garden experiments. These will include several different host environments to make it possible to evaluate whether the morphologic variation has a genetic basis or not.
During my Master thesis’ I studied pollination of the wild rice species Oryza longistaminata, and the possible consequences of hybridization with the cultivated rice species O. sativa. The project was partly financed by SIDA, and supervised by Åsa Lankinen and Samuel Kiboi.
