| Outline of Final Research Achievements |
In this study, we found that (1) five novel QTLs responsible for the transposition activity of mPing (qTmP4-qTmP8) are present in the genomes of the rice cultivar Gimbozu and Nipponbare, (2) mPing is mobilized in the test lines harboring anyone of the QTLs, (3) qTmP5 with the largest effect on mPing transposition among the QTLs controls mPing transposition not related to early embryogenesis-specific expression of the autonomous element Ping, and (4) there exist many Gimbozu-related landraces exhibiting higher transposition activity than Gimbozu. These results indicate that five QTLs detected in this study were effective for the mobilization of mPing even in elite rice varieties, such as Koshihikari, without mPing transposition activity.
