Abstract
Evolutionary and ecological genomics, in conjunction with molecular genetics and ecology, has opened the way for a comprehensive understanding of biological adaptations. The basic data are genomic information on multiple individuals, which is being accumulated using model species such as Arabidopsis thaliana and Oryza sativa. Evolutionary genomic analyses provide tools for identifying ecologically relevant genes, which I will illustrate through the study of reproductive isolation using recombinant inbred lines and linkage disequilibrium analysis. Moreover, it provides tools for detecting natural selection. As an example, I will talk about positive natural selection on a selfing locus, pseudoSCR1, in Arabidopsis thaliana. These results supports Darwin's hypothesis in 1876 that selfing can be advantageous when pollinators or mates are scarce in spite of inbreeding depression. I will briefly mention future perspectives including advantages of using plants.
