Mechanisms of adaptation in Oryza and Arabidopsis
Here I present a dissertation aimed at understanding the mechanisms of adaptation in two wild rice species and locally adapted populations of Arabidopsis thaliana. First, I assess the genetic architecture of adaptation in the wild progenitors of cultivated rice, by identifying QTL for a number of putative adaptive traits. Through this work flowering time was revealed as a key adaptation for habitat preference between these species. In the next chapter I attempt to elucidate the genetic basis of a major flowering time QTL through fine mapping. I continue my examination of flowering time genetics by examining the genetic basis of flowering time differentiation between locally adapted populations of Arabidopsis thaliana. Finally, I conduct a thorough study of comparative floral biology to identify key traits that control mating system divergence between the wild rice relatives. This work sets the stage for future efforts to understand the genetic basis of mating system evolution.
