Abstract
Transposons are genomic parasites, which constitute a major component of eukaryotic genome. RNA silencing machinery is a defense system against them, which suppresses transposons to stabilize host genome. It is a nature of transposons as a selfish DNA element to increase their copies, despite the presence of this defense system. This implies the existence of a pathway, which enables transposons to escape defense of host. In this presentation, we will introduce a strategy of a transposon to escape from its defense of host, in which transposon derived small RNA targets silencing machinery of host. Similar to this situation, some RNA viruses utilize RNA silencing pathway to overcome the defense of host. In this presentation, I will discuss a possible mechanism of transposons escaping from silencing of host and its contribution to genome evolution in rice.
