| Outline of Final Research Achievements |
Outermost cell layer of endosperm, aleurone, works for mobilization of storage materials in cereal grains. In contrast, aleurone works mainly as a barrier of germination in dicot seeds. In this study, we found TRG2A gene as an important factor for aleurone layer development and/or maintenance by using Arabiodpsis mutant that lost all the endosperm cells during seed development. TRG2A protein was found to be localized in cytoplasm and interact with adaptin subunits. We found that CHMP1 is also involved in aleurone development in Arabidopsis. Our findings indicate that vesicle transport system has critical role on aleurone development.
