| Research Abstract |
In angiosperms, a zygote generally divides into an asymmetric two-celled embryo consisting of an apical and a basal cell with different cell fates, and this unequal division is a putative first step for formation of the apical?basal axis of plants. In the project, apical and basal call specific genes were identified using rice in vitro fertilization system and single cell transcriptome analyses. In addition, preparation of transformed rice plants for visualizing actin filament made it possible to observe dynamics of actin filament during zygote development.
