| Research Abstract |
Species differ in their population structure and life history. In order to investigate effects of these differences on gene evolution, we investigated genetic variation in three characteristics tree species belonging to Cupressaceae and Rutaceae. We found that these four species have different genetic structures shaped by their attributes concerning population structure and life history. Also we found a few examples of action of selection reflecting those attributes.
