| genetic diversity and differentiation processes in the ploidy series of olea europaea l.: a multiscale approach from subspecies to insular populations. | geographical isolation and polyploidization are central concepts in plant evolution. the hierarchical organization of archipelagos in this study provides a framework for testing the evolutionary consequences for polyploid taxa and populations occurring in isolation. using amplified fragment length polymorphism and simple sequence repeat markers, we determined the genetic diversity and differentiation patterns at three levels of geographical isolation in olea europaea: mainland-archipelagos, isla ... | 2009 | 19143937 |
