| Research Abstract |
Inter-specific/generic crosses in higher plants often fail to produce germinatable seeds. This means the presence of genome barriers in seed development. Thus, we explored regulatory mechanisms of seed formation in various aspects. Through these studies, we identified and characterized ENLI gene, which was found essential exceptionally to rice (or cereal) endosperm development at early stages. We also revealed the involvement of epigenetic mechanisms in both positive and negative seed-specific gene regulations.
