Research Abstract |
We identified QTL region located on the long arm of chr.1. The locus causes hybridization barrier of rice endosperm in the cross of female O. sativa cv. Nipponbare and male O. longistaminata. In addition, we investigated and compared detailed endosperm development in interploidy and interspecific crosses. As a result, both cases show very similar endosperm phenotypes and patterns of developmental transitions, but in the nuclear division rate of endosperm.
