| Outline of Final Research Achievements |
In this study, we found that (1) a rice active transposon mPing alters transcript structures post-transcriptionally via induction of alternative splicing that most likely depends on DNA methylation, (2) a Myb-like protein encoded by the autonomous element Ping can bind to mPing sequence independently of DNA methylation, and (3) early embryogenesis-specific expression of Ping may be regulated by a SNP in Ping-ORF1 or position- and dosage-effect of Ping. These indicate that mPing can amplify in the rice genome by escaping from the epigenetic regulation and consequently contributes to the enlargement of genetic variability of the host genome.
